Why WILLIWAW? 

reSAWN TIMBER co. offers a variety of Alaskan Yellow Cedar options that all contain the incredible benefits of this species. WILLIWAW not only has all of those benefits, but is loved for its natural variation, pre-weathered features, and low maintenance. 

From afar, WILLIWAW exhibits a light beige color with gray undertones, making it unique looking in every kind of lighting. Its color compliments every environment it’s surrounded by whether it’s mountains or beaches, sun or snow, it provides a natural look as if it has always belonged there. The natural color variations in Alaskan Yellow Cedar wood are primarily due to the wood’s interaction with minerals found in the soil of its growing environment. As the tree absorbs water and nutrients from the soil, it also absorbs trace amounts of minerals present in the surrounding environment. These minerals can include iron, copper, manganese, and others, each imparting its own color properties to the wood. The mineral composition of the soil plays a crucial role in determining the color variation.

WILLIWAW is prefinished in plant-based, zero VOC finish, allowing it to accept and hold finishes with minimal aesthetic variation throughout its installation lifecycle. reSAWN’s products arrive at job sites prefinished to avoid minor mishaps that can occur on job sites like oversprays, streaks, drips, or lap marks. Drying racks that are used to hold wet cladding on a job site are costly and take up much-needed space. Prefinished wood materials like WILLIWAW are finished and dried in a controlled environment prior to arriving on a job site. With factory-finished products, they have already undergone quality control, inspection, and back coating to ensure the material is in perfect condition before it arrives at its destination.

WILLIWAW is offered in a clear vertical grade, meaning the growth rings are parallel to each other on the face or the board, and very light skips on the non-graded face. Architects and builders often seek out select grades because it has very few imperfections or character markings, making it look smooth and clean. Additionally, WILLIWAW is utilized for both interior and exterior purposes, making it versatile and flexible for all styles of design. 

WILLIWAW is currently being installed on homes in different climatic zones across the country in South Carolina, Minnesota, California, Florida, and Canada. Below is the Red Mountain Residence in Aspen, Colorado on its way to completion.

Alaskan Yellow Cedar Benefits

At reSAWN, our Alaskan Yellow Cedar products like WILLIWAW are ideally suited for any interior and exterior project, including wall and ceiling cladding. With its versatility, comes many remarkable benefits. 

  • Durability– AYC has exceptional resistance to decay, rot, fungi, and insect damage. Due to their natural extractives such as Thujaplicans and Phenolics, they act as a defense mechanism for decay-causing organisms and pests. The natural oils also act as a natural barrier against moisture, helping to repel water. This contributes to the long lifecycle of the wood.
  • Strength– The low density and compact characteristics of the species make it more resistant to wear, impact, checks, and twists. Additionally, its straight grain pattern contributes to the strength of the wood. The fibers in AYC run parallel to the board’s length, providing structural integrity, making it less susceptible to shrink, and enabling it to withstand various environmental and structural stresses.
  • Insulation– The species’ tightly packed fibers and low density allow the wood to be thermally insulated. 
  • Fire Resistant– When exposed to fire, AYC tends to have a slower burn rate. It releases heat at a slower pace and retains its structure for a longer period. reSAWN’s AYC has a Flame Spread Index of 40 and a Smoke Developed Index of 140, giving it a Class B Rating.

Why is Wood the Most Mimicked Building Material?

By Jocelyn Mahan In Wood University /  3 No Comments

Humans have always connected deeply with nature because we evolved in natural environments. For thousands of years, we have lived in close proximity to nature, relying on it for survival. Our brains and bodies evolved to function in these natural environments, and as a result, we have an innate connection to nature that has persisted throughout human history. Even as we have become more urbanized and modernized, our connection with nature has remained strong because it is ingrained in our biology and psychology.

According to several authoritative studies (Workplaces: Wellness+Wood=Productivity), (Wood: Nature Inspired Design), and (Why Do We Feel Better With Wood?) exposure to natural products like wood creates similar health benefits to those created by spending time in nature. Incorporating natural materials such as real wood cladding and flooring into a built environment helps reduce blood pressure, heart rates, and stress levels while improving well-being, creativity, cognitive abilities, and the air we breathe. The concept of biophilia was introduced in the 1980s to highlight the importance of our connection to nature and the potential benefits that can be gained from it. 

Synthetic building materials often recreate the look of wood because wood is a popular and traditional building material that has been used for centuries. Wood’s warm, natural look and feel is difficult to achieve with non-natural materials. By mimicking wood, manufacturers can create low-cost building materials with a similar appearance and texture to wood, but lacking the warmth, intrinsic qualities, and health benefits afforded by real wood materials. 

The influence that wood has on the building materials market can be seen everywhere. reSAWN recently attended the 2023 International Builders’ Show (IBS), which is an annual trade show for the residential construction industry, hosted by the National Association of Home Builders (NAHB). The show featured exhibits and educational sessions focused on new products, innovative technologies, and industry trends related to home building and remodeling. The use of wood, wood influence, and the creation of wood-like aesthetics was prevalent throughout the show. Even companies that were not offering a wood product, utilized wood-like textures in their booths to highlight their product or service.

Vinyl Siding Made to Look Like Wood

Vinyl siding is a popular choice in the US for a wood-like look without the perceived maintenance. Vinyl can be made to look like different types of wood, including cedar, oak, and pine. It is also affordable and durable, making it a common choice for many projects. However, there are some potential downsides to using vinyl siding that need to be considered. 

  • Vinyl siding is made of polyvinyl chloride (PVC), a plastic material that is derived from petroleum – which is a non-renewable resource. The production of PVC and its disposal can result in toxic pollutants being released into the environment, including dioxins, which are known to be harmful to human health and the environment.
  • Energy-intensive manufacturing: The production of vinyl siding requires a significant amount of energy, mainly from non-renewable sources such as coal and natural gas, which contributes to greenhouse gas emissions and climate change.
  • Limited recyclability: Vinyl siding is difficult to recycle, and it may end up in landfills where it can take hundreds of years to break down. This contributes to environmental pollution and wastes resources.
  • Installation and maintenance: The installation of vinyl siding requires the use of various chemicals and solvents, which can have negative environmental impacts. In addition, vinyl siding can crack or fade over time, requiring replacement, which leads to more waste.

Fiber Cement Made to Look Like Wood

Another material that mimics the look of wood is fiber cement. It’s a widely used building material that’s made from a mixture of cement, sand, and cellulose fibers. While it has many benefits, such as durability, fire resistance, and low maintenance, there are also significant environmental issues associated with its production and use. 

  • Carbon emissions: The production of fiber cement involves high energy consumption and emits significant amounts of carbon dioxide, contributing to global warming.
  • Water use: The production of fiber cement requires a significant amount of water, which can put pressure on local water resources in areas where water is scarce.
  • Waste disposal: The production process generates a significant amount of waste, including cement dust, which can cause air pollution if not properly disposed of.
  • Toxicity: The production of fiber cement can result in the release of toxic chemicals, such as asbestos, silica, and formaldehyde, which can pose health risks to workers and nearby communities.
  • Transportation: Fiber cement is a heavy and bulky material that requires a lot of energy to transport, contributing to greenhouse gas emissions.

Composite Decking Made to Look Like Wood

Composite decking is a popular alternative to traditional wood decking because it is durable, and requires little maintenance. However, there are some environmental issues associated with composite decking that should be considered.

  • Manufacturing: The production process of composite decking involves the use of a variety of chemicals, including resins, wood fibers, and plastics. These chemicals can release harmful emissions into the air and water during production.
  • Disposal: Composite decking materials are not biodegradable and can take up valuable space in landfills if not properly recycled. Some composite decking materials contain hazardous chemicals, making them difficult to recycle or dispose of safely.
  • Non-renewable resources: Most composite decking is made from a combination of wood fibers and plastic, both of which are non-renewable resources. This means that the production of composite decking contributes to the depletion of these resources.
  • Maintenance: Although composite decking requires less maintenance than traditional wood decking, it still requires periodic cleaning with chemicals that can harm the environment. However, with the onset of modified woods like Accoya, there are now many maintenance-free options on the market.

Porcelain Tile Made to Look Like Wood

One of the newest materials to mimic wood is porcelain tile. Porcelain tile can be made to look like different types of wood, including oak, maple, and walnut. It is also very durable and water-resistant, making it a great choice for areas that experience moisture or high traffic.

Porcelain tile is generally considered an environmentally friendly flooring option, as it is made from natural materials such as clay and minerals, and can be recycled at the end of its life. However, there are some environmental issues associated with porcelain tiles that should be considered:

  • Energy consumption during production: The production of porcelain tile requires a significant amount of energy, which contributes to greenhouse gas emissions and climate change.
  • Water usage during production: The production of porcelain tile requires large amounts of water, which can contribute to water scarcity and pollution.
  • Transportation emissions: Porcelain tile is often imported from overseas, which results in transportation emissions and contributes to climate change.
  • Waste generation: The installation of porcelain tiles can generate waste, including cut-off pieces and broken tiles, which can contribute to landfill waste.
  • Chemicals used in production: The production of porcelain tile may involve the use of chemicals such as glazes and sealants, which can be harmful to the environment if not properly managed.
  • When a single design is repeated over a large area, it can create a visual monotony that may appear repetitive.

Laminate Flooring Made to Look Like Wood

Laminate flooring that looks like wood is a popular choice for many homeowners and builders because it provides the appearance of hardwood flooring at a more affordable price. Laminate flooring is made from composite wood materials and is designed to mimic the look of hardwood planks, including the texture and grain patterns.

While laminate flooring has many advantages, there are some drawbacks to consider before choosing it for your home or building project. 

  • Not as durable as hardwood: Although laminate flooring is more durable than some other types of flooring, it is not as durable as hardwood. Heavy furniture, high heels, and pet claws can all cause scratches and dents in laminate flooring.
  • Susceptible to water damage: Laminate flooring is made from a wood-based core, and as such, it can be damaged by excessive moisture or water exposure. Spills or leaks that are not cleaned up quickly can cause the planks to warp or buckle.
  • Can look artificial: While laminate flooring is designed to look like real wood, it is still an artificial product, and some people may find that it looks less authentic than hardwood flooring.
  • Difficult to repair: If a section of laminate flooring becomes damaged, it can be challenging to repair without replacing the entire plank or section of the floor. This can be costly and time-consuming.
  • Formaldehyde emissions: Formaldehyde is a chemical used in the adhesives and resins used to make laminate flooring, and it can be emitted into the air over time. Formaldehyde is a known carcinogen and can cause health problems, especially for those with respiratory issues. However, many laminate flooring manufacturers now use low-formaldehyde adhesives and resins to reduce the risk of emissions.
  • Sustainability of materials: The majority of laminate flooring is made from a core of high-density fiberboard (HDF) made from wood fibers, which can be derived from unsustainable sources such as old-growth forests. While some manufacturers use recycled or sustainably sourced wood fibers, others may not be as environmentally responsible.
  • Disposal: Laminate flooring cannot be easily recycled and may end up in landfills. When disposed of, it can release formaldehyde and other harmful chemicals into the environment. However, some companies have started recycling programs to reduce waste and environmental impact.
  • Short lifespan: Laminate flooring is generally not as durable or long-lasting as other flooring materials, such as hardwood. This means that it may need to be replaced more frequently, leading to more waste and environmental impact.

While laminate flooring is a popular and affordable option, it may not be the best choice for all situations. To mitigate the environmental issues associated with laminate flooring, consumers can look for products made from recycled or sustainably sourced materials, choose low-formaldehyde options, and properly dispose of old flooring. It is also important to select flooring that is durable and has a long lifespan to minimize waste and environmental impact.

Aluminum Made to Look Like Wood

There are some manufacturers that offer aluminum facade solutions for homeowners and commercial properties looking to achieve the look of wood. The aluminum products mimic the appearance of natural wood grains, knots, and textures.

While aluminum facades offer numerous advantages such as durability, flexibility, and low maintenance, there are also some disadvantages that should be considered, including:

  • Cost: Aluminum facades can be expensive compared to traditional wood cladding materials.
  • Corrosion: Aluminum is susceptible to corrosion if it is not properly treated or coated. Exposure to moisture and chemicals can lead to rust and discoloration, which can detract from the appearance of the building.
  • Thermal conductivity: Aluminum is a good conductor of heat, which can lead to energy loss in buildings. Additional insulation may be required to offset this problem.
  • Environmental concerns: The production of aluminum requires a significant amount of energy and generates greenhouse gas emissions. Additionally, the extraction and processing of aluminum can have negative impacts on the environment.
  • Limited design options: While aluminum is a flexible material, there may be limitations to the design options available with this cladding material. Some architects and designers may prefer other materials for their aesthetic appeal or greater design flexibility.
  • Scratches and dents: Like all aluminum cladding materials, Knotwood is susceptible to scratches and dents, which can detract from its appearance.

Technological Updates in Wood

There have been many recent technological updates in the use of wood as a building material, which have made it more versatile, efficient, durable, and dimensionally stable.

Modified Wood Options

Various environmentally friendly chemical and heat treatments can be used to modify the properties of wood. For example, acetylation can make wood more durable and resistant to decay, while thermal modification can improve its stability and strength. This type of wood requires minimal upkeep to preserve its appearance and structural integrity over time. Low-maintenance modified wood products can be a great option for homeowners who want the beauty and warmth of wood without the hassle of regular maintenance. However, it’s important to choose the right type of wood for your specific application and to follow any recommended maintenance guidelines to ensure that your wood products last as long as possible.

Structural Analysis Software

Structural analysis software can simulate the performance of wood structures under different loads and conditions, allowing engineers and architects to optimize designs for strength, durability, and efficiency. This technology has led to the development of new building systems and techniques that use wood in innovative ways.

Sustainable Forestry Practices

Technology has made it possible to manage forests more sustainably, by using satellite imagery, remote sensing, and other tools to monitor forest health, track tree growth, and identify areas of concern. This technology has helped to reduce the environmental impact of harvesting wood while ensuring a steady supply of sustainably harvested timber for building and other uses.

Overall, technology has helped to make wood a more versatile, efficient, durable, and dimensionally stable building material, opening up new possibilities for architects, engineers, and builders to create innovative and sustainable structures. Moreover, wood has a natural warmth and character that is difficult to replicate with synthetic materials. While there are synthetic materials that can mimic the appearance of wood, they often fall short in terms of sustainability, texture, color variation, and overall aesthetic appeal. 

Wood is one of the most mimicked building materials because of its adaptability, availability, and natural beauty. It can be shaped, cut, carved, and finished in a variety of ways, allowing it to be used for a wide range of applications, from furniture and flooring to building construction. In summary, while alternatives to natural wood products may have some advantages, they may not be able to fully replace the environmental and authenticity benefits that come with using natural wood. Plus due to technological updates in the use of wood as a building material, it is more versatile, efficient, durable, and sustainable than ever before.

What is Thermally Modified Wood?

By Jocelyn Mahan In Abodo Vulcan Slats, Low Maintenance Finishes, Thermally Modified Wood, Wood University /   No Comments

Thermal modification is a process that utilizes high heat to alter the dimensional composition of wood. The cellular structure is changed by applying heat without oxygen, which creates a controlled chemical reaction. The thermal modification process permanently modifies the cell walls of the wood and results in improved durability of the wood as well as increased dimensional stability.

Three Falls Residence – GRAPHITE Abodo Vulcan Cladding

The aim of modified wood is to overcome the shortcomings of standard timber. The modification process enhances the performance of the wood, resulting in improvements in the longevity of timbers – dimensional stability, decay resistance, reduced water absorption, less expansion/contraction, etc. In addition, since most advanced modification processes are environmentally friendly, the materials can still be disposed of properly at the end of the product life cycle.

Vancouver-Residence-ft-KOS-Shou-Sugi-Ban-Kebony
Vancouver Residence  – KOS Shou Sugi Ban Charred Kebony

What Are The Benefits of Using Thermally Modified Wood?

Durability: Wood becomes instantly more durable after being thermally modified. Water absorption in regular wood can cause warping, discoloration, and even the growth of bacteria or fungi. This is not an issue with thermally modified wood. Water cannot warp or deform it because the modification process naturally changes the cellular structure of the wood.

Aesthetics: Thermally modified wood has a beautiful, consistent chocolate-brown color from surface to core.

Sustainability: Solid wood building materials have a net-negative CO2 profile – better than any conventional building material. It requires less energy to create the finished product than other building materials such as concrete, metal, or plastic.

Environmentally Friendly: Many exterior wood products are treated with wood preservatives – some more toxic than others. The thermal modification process uses heat and steam to cure the wood. There are no harmful toxins or chemicals that are used in the process.

Abodo Thermal Modification Process:

Phase 1 – The kiln is slowly elevated in temperature until the moisture content of the wood is essentially zero %. The wood in the kiln is then heated further until it reaches the desired modification temperature – in most cases 230 degrees Celsius for outdoor end-use applications.

Phase 2 – The kiln is held at the modification temperature for a prescribed time to achieve full modification. This time is the critical point in the process.

Phase 3 – The kiln is allowed to cool, and the wood is reconditioned with steam (we bring the moisture content back to around 7%). Once cool enough the wood can be extracted from the kiln.

reSAWN TIMBER co. is proud to be the exclusive manufacturer and distributor of Abodo® thermally modified Vulcan cladding and decking products in the USA.

Kebony Modified Wood

Kebony is considered a dually-modified wood, which means it’s both chemically and thermally modified. That happens through their proprietary process called furfurylation. The Kebony technology modifies wood by forming stable, locked-in furan polymers in the wood cell walls. These increase the dimensional stability, as well as durability and hardness, of the wood. This process is based on impregnation with furfuryl alcohol produced from agricultural crop waste. Kebony thus uses a plant-derived waste product to give enhanced strength and durability to another plant product – namely wood.

Kebony Decking
Kebony Clear Decking

Kebony wood is safe since the wood does not splinter and doesn’t contain toxins or chemicals, nor does the wood get too hot in the summer. Furthermore, Kebony wood is resistant to rot and fungi, and other wood-destroying microorganisms in an above-ground context. Kebony is a low-maintenance material that does not require additional treatment beyond normal cleaning, thus, no oils or other impregnation solutions are needed. 

Thermally Modified Red Oak

Thermally modified red oak is a popular option for locally sourced timber from the United States. In North America, red oak trees are prevalent and grow to a height of around 70 feet and a trunk diameter of 36″. Being the largest species group, it is highly sustainable.

While there are copious amounts of international building material manufacturers, local suppliers can offer benefits that overseas vendors cannot.

Carbon Footprint Reduction – Our relationship with our environment truly matters. Building materials that are locally sourced means shorter trips to haul, less greenhouse gas emissions, and less diesel fuel consumption.

Support Products Made in the USA – By specifying local materials, a product’s sustainability profile extends to extraction, manufacturing, and transportation practices.

What Are Rain Screen Cladding Systems?

By reSAWN TIMBER co. In Featured In The News, Wood University /  1 No Comments

The building enclosure (envelope, skin, facade, etc.) represents one of the greatest risk elements of construction. It is subjected to various weather conditions and must be constructed to endure long-term deterioration and weathering. There are numerous options for installing exterior cladding. In order to combat water penetration, air leakage, and increased energy consumption, hygroscopic materials such as wood are best suited for rainscreen applications. 

Building Enclosure

Rain and snow, the two most common types of water that fall on an exterior wall, are either pushed downward by gravity or pushed sideways by the wind. A rainscreen deploys an outside surface – a rainscreen cladding layer – to break the power of sideways, wind-driven water movement, allowing any water that passes through the microscopic gaps in the surface to lose speed. The majority of water merely bounces off the surface or runs down the side of the building.

Rainscreen Sub-Structure
Rainscreen Sub-Structure

Moisture-Control Functions Within a Rainscreen:

Drainage: Lapped or interlocked exterior wood cladding resists most moisture from the elements, but it is not watertight. An air gap behind the cladding combined with a means of egress provides a path for moisture to escape the wall assembly. Open-joint rain screens that maintain physical openings between the boards also have a gap and a drainage path behind the boards. In a wood cladding installation, the drainage gap is created by installing furring strips or girts over the water-resistive barrier. 

There are also drainage matrix products that are designed to create drainage stand-off within their own thickness, eliminating the need for furring strips. These are commonly known as building wraps that combine the functions of a drainage plane, water-resistive barrier, and an air barrier into one product. reSAWN conventionally views assemblies that employ a matrix as less desirable for overall drying when compared to fully gapped assemblies that include furring strips. Though, drainage matrix products can be better suited for retrofit projects where a true rainscreen application isn’t feasible.

Break: The presence of an air gap limits the wicking transfer of absorbed moisture from material to material into the wall assembly.

Vent: Adding a ventilation path at the top of a rainscreen allows the vented opening –  with the drainage opening at the bottom of the wall assembly – to enable convection in the air gap behind the cladding. The airflow promotes additional drying within the assembly. 

Successful rainscreen designs consist of numerous chosen components that allow for a range of options to fit any project’s needs. A thorough understanding of a project site’s climatic dynamics should inform rain screen design.

SIOOX Abodo Vulcan Cladding

There are numerous high-quality components on the market that aid in the design of a successful rainscreen. Making high-quality detail choices throughout the design process and taking into account the whole wall assembly – from the exterior to the interior – can assist in the long-term utility and durability of a given rainscreen. 

Membranes: Wall assemblies need to dry after wet weather conditions. Based on their design, wall assemblies dry inward, outward, or in both directions. 

Water-resistive barriers block moisture and are often code-mandated in residential applications.  In simplest form, these barriers are building wrap products attached to a building’s sheathing with mechanical fasteners or adhesives. In most cases, they are continuous or layered shingle-style across an entire facade.

Air barriers block air movement.  Many building components in a wall assembly have air-blocking characteristics. To create fully effective air barriers, these materials should be combined with a system to ensure an envelope effect. Special attention must be given to openings such as windows and doors, transitions from wall to roof planes, and penetrations for mechanical and electrical intakes and outlets. An air barrier system is composed of a membrane supported by sheathing, seam tape, and specialized gaskets and seals at penetrations. Air can carry high amounts of moisture, so limiting the amount of air that can move through a wall assembly can help the likelihood of the enclosed portions of a wall staying dry. 

Vapor barriers limit vapor diffusion. How much vapor movement a material experiences is known as its permeance value. Virtually all sheet, bat, or board building products have specific permeance determined by their composition and thickness. Vapor membrane products are specifically designed to limit vapor diffusion. Other products such as insulation have permeance as well. While their primary purpose is not vapor diffusion, as a component of the wall assembly, they have an impact. Efforts should be made to thoroughly research materials that make sense for the climate zone and project specifications. Negative impacts can occur within a wall assembly by the incorrect placement of a barrier with high vapor-blocking characteristics such as a polyethylene sheet. One of the greatest challenges occurs when a vapor barrier intended to keep a wall assembly from getting wet actually prohibits it from drying1.

The primary functions of water, air, and vapor barriers can be combined. While the needs of every application are project-specific, reSAWN sees repeat success in wood-clad rainscreen assemblies with the application of combined water and air barrier membranes that are also breathable, to allow any moisture present in the wall assembly to escape outwards.

Details:

A wall assembly’s success starts with attention to detail – including the project site conditions and material selection. The list below includes a limited sampling of some high-impact items.

  • Material Movement: When specifying wood cladding, an understanding of wood and its movement is imperative. Intentional allowances for the expansion and contraction of all wood components should be considered. Adequate interlocking (i.e. tongue and groove)or lap conditions should be planned to inhibit separation between boards for material contraction. Depending on the cut of the wood cladding (specific to grain orientation), the primary axis of movement in relation to the board’s orientation as installed may vary.
  • Material Stability and Sizing: The stability of wood, meaning how the wood maintains its original shape and dimension, is important within a rainscreen. Properties such as wood grade and wood modification can increase stability. Stability should play a central role in the cladding selection process, and this same process should be applied to the selection of the furring strips to which the cladding is fastened. The width and thickness of furring strips should allow for the intended depth of the drainage gap and also ensure a durable target for both the fasteners that tie the furring strips back into the wall’s structure as well as the fasteners that attach the wood cladding to the strips. 
  • Fastener Choice: A stainless steel wood-to-wood fastener is an important component of a wood-clad rainscreen assembly. A project site’s geography can influence the grade of steel fastener used, as some may be more appropriate in coastal or other specialized climates. Nails should be ring shank siding nails. Screws should be appropriately sized to limit the potential of breaking and splitting when driven into the cladding.  Head shape, size, color/coating, and the appropriateness of piloting fastener holes as well as fastener length in light of the self-synching/sealing properties of the water-resistive and air barriers should all be considered.
  • Penetrations:  All penetrations through a rainscreen from windows to exhaust ducts should be thoroughly flashed and air sealed. 
  • Continuity of Detailing: Detailing at corners, facade transitions, trims, sills caps, and like conditions can be challenging. Taking into account allowance for expansion, rear drainage, mitigation of pest infiltration, or vented channels are all important details to keep in mind during all project stages.
  • Durability During Construction: Components of a project will likely be exposed to the elements during the construction phase. Care should be taken to review how these components weather and react to UV exposure, as they will likely have exposure to the elements before the full assembly is complete. Many products sold specifically for applications in rainscreens are designed to be durable throughout the more rugged challenge of a project’s construction timeline.
  • Adherence to Product Guidelines:  All application-specific information provided by component manufacturers should be reviewed during the design, pre-construction, and construction phases of a project.

VIDEO: Accoya Exterior Wood Cladding in 1 Coat & 2 Coat Options

By Jocelyn Mahan In CHARRED WOOD, In the Field, Low Maintenance Finishes, Maintenance /   No Comments

In this video & article, we discuss reSAWN’s Accoya modified wood offering which is prefinished with a waterborne exterior oil. Our one-coat (1C) and two-coat (2C) product offerings provide specifiers with the choice of a more saturated color if desired.

1C Option – Finished with 1 Coat

‘1C’ denotes Accoya wood that is prefinished with one coat of our proprietary exterior oil in the factory. There is no need to apply a second coat of finish post-install.

2C Option – Finished with 2 Coats

‘2C’ denotes Accoya wood that is prefinished with one coat of our proprietary exterior oil in the factory AND will require the installer to apply a second coat of finish post-install. This finish will be included on the sales order and shipped with the materials.  Applying a second coat of finish post-install will further saturate the initial color of the cladding and extend the duration of the deeper color.  

The video focuses on RAILAY 1C and RAILAY 2C, two of reSAWN’s Accoya wood products with a waterborne exterior oil.

Video Transcript:

Hi, I’m Diane with reSAWN TIMBER, and I’m here today to talk to you about several of our Accoya products that are available with 1C or 2C exterior finish. 1C indicates Accoya is prefinished with one of our exterior oils in the factory, and this does not require a second coat. 2C indicates Accoya is prefinished with one of our exterior oils in the factory, which will require a second coat onsite by the installer.

The big difference between 1C and 2C is the color saturation on day one and as it weathers over time. Applying a second coat of Accoya does enhance the initial color of the exterior cladding and it extends the life of that deeper color over time. However, if you choose not to apply that second coat of finish, that can be a cost savings for your project.

I’m here at the factory in Pennsylvania and we do testing of our own products outside on our weathering rigs. We test for aesthetics and performance. So here are two examples. This is RAILAY 1C and RAILAY 2C – these have been outside on our weathering rigs since September 2021. That is 10 months of accelerated weathering. It’s considered accelerated weathering because it’s on our rigs on a 45 degree angle facing due South.

reSAWN TIMBER co. Accelerated Weathering Rigs

So 10 months of accelerated weathering represents approximately 30 months on the job site. So you can see they are weathering a little bit differently, but yet they’re weathering beautifully. So as you have your project needs or requirements for exterior cladding and Accoya modified products, give us a call at reSAWN TIMBER and we’d be happy to help you out. Thanks!

How is Accoya wood modified?

Accoya wood is modified through a process known as acetylation. Accoya takes radiata pine, a softwood, and subjects it to a vinegar known as acetic anhydride. Acetyls are naturally present in wood, and acetic anhydride enhances the hydroxyl groups, providing water-repelling characteristics. This process turns the softwood into a hardwood by preventing the cells in the wood from being able to absorb water. This vinegar is verified as non-toxic with Cradle to Cradle Certified Gold, scoring ‘Platinum’ for Material Health. This modification process gives Accoya its durability and rot and decay resistance.

Accoya wood accetylation process

Does Accoya wood require a lot of maintenance?

Not only is Accoya’s durability proven, but it has also been shown to retain its appearance, requiring much less frequent maintenance than other wood species. Since Accoya wood undergoes the acetylation modification process, it requires little to no maintenance. The modification process enhances the performance of Accoya wood, providing outstanding dimensional stability that results in lower maintenance frequency and therefore less coating over the lifetime of the product.

Accoya wood doesn’t require recoat maintenance. However, if the desire is to get back to that day one color, we do recommend a recoat for aesthetic purposes. Maintenance and recoating guidelines vary by product. Contact reSAWN TIMBER co. for product-specific information.

Introducing Grey Through Body Color Accoya® : For Interior, Exterior Cladding & Decking

By Jocelyn Mahan In New Products, Product Updates /  4

reSAWN TIMBER co.’s offering of Accoya® wood is expanding to include Accoya that has been impregnated with a non-toxic grey pigment for a through body color that is intended to be a living finish that will weather naturally in place and requires no maintenance – OXFORD, MARENGO, and GREY MATTER.

The advantage of these materials is that they are grey from day 1 and can be used to achieve consistent color on all exterior surfaces regardless of facing (north, south, east, west) or application orientation (cladding, roofing, soffits, underside of canopy). This grey color can also be seamlessly carried into the interior walls or ceilings.

OXFORD Through Body Color on Accoya Cladding

WHY SPECIFY ACCOYA?

Accoya is wood, but not as you know it. It is modified timber in which a process called acetylation, a cutting-edge patented technology, enables it to resist rot, defy the elements and stay strong for decades. With warranties starting at 10 years and going up to 50 years, its performance and properties are remarkable. From joinery for the home to bridges submerged in water, Accoya wood is a leading material that stands up to every application challenge – decking, cladding, and more.

OXFORD Through Body Color on Accoya Decking

WHAT ARE THE BENEFITS OF THROUGH BODY COLOR ACCOYA?

  • Guaranteed durability backed by warranties:
    • Commercial Warranty: 10 year warranty on Decking; 50 year warranty on cladding, trim, and millwork
    • Residential Warranty: 25 year warranty on Decking; 50 year warranty on cladding, trim, and millwork (except in Florida – for Florida commercial warranty length applies)
  • Beautiful grey color: The day one grey color means no wait time for a naturally grey product. The through body color grey ensures a consistently beautiful appearance from day one.
  • No maintenance: Due to the through body grey color, OXFORD, MARENGO, and GREY MATTER do not have to be re-oiled regularly or re-colored after scratches.
  • Barefoot friendly: In addition to Accoya’s durability and dimensional stability, Accoya wood rarely warps and hardly cracks or splinters. OXFORD, when used as decking, will feel soft underfoot in the long term.
OXFORD Through Body Color on Accoya Decking & Pool Deck Surround

WILL OXFORD, MARENGO, AND GREY MATTER STAY GREY?

Through body color Accoya products are colored grey from the surface to the core, requiring less maintenance. These products are grey from day one, so there is no need to wait for the wood to weather or naturally patina. The coloring will stay grey without oiling or re-dying. Since the grey color is all the way through the board, it also means scratches and scrapes are not visible.

WHY SPECIFY reSAWN’s THROUGH BODY COLOR ACCOYA?

We work with woods’ natural tendency to grey, not against it. Our products look beautiful on day one and continue to as nature takes over – with little to no aesthetic maintenance needed. Each board works cohesively together yet each board has its own visual story. The result is modern originality & inherent textural beauty with each and every project.

Designing with Wood For a Sustainable Future

By Jocelyn Mahan In In the Field, Wood University /  4 No Comments

Using sustainable building materials in the built environment is a top priority now, more than ever. Building and designing a structure in the modern era should include consideration for the long-lasting impact of all facets of the design and build process. Due to this shift in focus on sustainable building materials, wood flooring and exterior wood cladding are frequently sought out as sustainable building materials to specify. In addition to its environmental and sustainability attributes, wood has multiple benefits, including its aesthetic qualities, versatility, structural stability, and availability.

Environmental & Structural Benefits of Using Wood Cladding as an Exterior Building Material

According to the Environmental and Energy Study Institute, residential and commercial buildings are responsible for almost 40 % of U.S. carbon dioxide emissions1. Fortunately, utilizing exterior wood cladding helps to offset the emissions.

  • Wood is a carbon sink: Trees absorb carbon from the environment and hold onto the carbon through their life cycle – from a tree to building material. They use the energy from carbon dioxide in the air, sunlight, and water from the roots to create nutrients that fuel the rest of the tree. This means that solid wood building materials have a net-negative C02 profile, which helps reduce carbon emissions.

  • Wood has low embodied energy: Embodied energy is the total energy needed for extraction, processing, manufacturing, and delivery of building materials to a building site. Wood requires minimal energy to produce and install when compared to other building materials such as steel and concrete.
  • Wood has low thermal conductivity: Structures built with real wood cladding require less energy to heat and cool since wood is a natural insulator.
  • Renewable resource: Real wood is renewable, recyclable, and biodegradable meaning it will have less of an impact on the environment throughout its lifecycle.
  • Durability: When properly maintained, exterior wood cladding can stand the test of time. This makes wood an eco-friendly choice compared to other materials that require more maintenance or replacement. Different finishing processes can also help extend the life of the cladding.
  • Dimensional stability: Wood’s superior dimensional stability helps it perform well when exposed to the elements such as the sun, snow, and rain.

Benefits of Wood Based Designs in Interior Applications

Americans spend a whopping 93 percent of their lives indoors breathing in recycled air. What most don’t realize is the air we breathe indoors is on average 2X to 5X more toxic than what we breathe outdoors due to insufficient ventilation, synthetic building materials, and volatile organic compounds (VOC) from a variety of products and materials. Thus, for many people, the health risks related to indoor air pollution may be greater than that of outdoor exposure.

The Enclave featuring BRIZA Weathered Atlantic White Cedar Interior Cladding

Incorporating natural materials such as real wood flooring into a built environment helps to reduce blood pressure, heart rates, and stress levels, whilst improving well-being, creativity, cognitive abilities, and the air we breathe. Wood flooring is a timeless option, as it has been a favored building material for years. With multiple species, finish options, color variations, widths, and grade options, it can easily match any design aesthetic. When properly installed and maintained, wood floors can outlast many other flooring materials. reSAWN offers solid and engineered construction wood flooring that not only looks great but is sustainable as well.

  • Long-Lasting and Durable: Whether solid or engineered construction, wood flooring is durable and can withstand the wear and tear of everyday life. This durability means a longer lifecycle for the product, especially when refinishing is considered instead of replacing. A recent report from Bona found a 78% carbon footprint reduction when refinishing rather than replacing wood floors2.
  • Better Air Quality: The EPA found that wood flooring improves overall air quality3. Wood flooring minimizes the acclimation of dust, dander, and other pollutants due to its solid surface. Choosing a finish that has a low to zero VOC content is also attributed to the air quality. reSAWN’s Hardwax-Oil finish is non-pollutant and completely non-toxic. It does not contain biocides, preservatives, or lead-benzene and is 100% VOC-free.
  • Biophilic Design: Numerous studies have found incorporating aspects of nature into the built environment, such as real wood flooring, can help the mental health and wellbeing of the building’s occupants.

Certifications for Green Building Initiatives

There are many certification programs that are often used by architects, designers, homeowners, and builders as guidelines and a solid framework for sustainable building initiatives. Although different programs have varying levels of standards, they all focus on building a healthier, more sustainable future in both the commercial and residential building sectors. At reSAWN TIMBER co. we focus on LEED®, Forest Stewardship Council (FSC®), and The Living Building Challenge.

LEED

LEED, also known as Leadership in Energy and Environmental Design, is the most widely used green building certification system in the world. LEED-certified buildings save money, improve efficiency, lower carbon emissions, and create healthier places for people. Most projects, whether it’s new construction, a renovation, or an interior fit-out can apply for LEED credits.

A project earns LEED points/credits by following guidelines relating to carbon, energy, water, waste, transportation, materials, health, and indoor environmental quality. Points can be earned for each recognized green building feature. The more points obtained, the higher level of certification a project can achieve. The different levels of certification include LEED Certified, LEED Silver, LEED Gold, or LEED Platinum. A 2014 UC Berkeley study4 found that by building to LEED standards, buildings contributed 50% fewer greenhouse gasses than conventionally constructed buildings due to water consumption, 48% fewer greenhouse gasses due to solid waste, and 5% fewer greenhouse gases due to transportation.

According to LEED:

  • 35% of credits are related to climate change
  • 20% of credits directly impact human health
  • 15% of credits impact water resources
  • 10% of credits affect biodiversity
  • 10% of credits related to the green economy
  • 5% of credits impact the community
  • 5% of credits impact natural resources

A factor of LEED certification is material selection. Material selection can affect many aspects of a project, including comfort, air quality, and human health. reSAWN TIMBER co. lists earnable credits on all our products, so you can know firsthand what credits your project qualifies for. Some of the common credits reSAWN products qualify for include certified wood, rapidly renewable materials, and low-emitting materials.

FSC®

FSC®, also known as the Forest Stewardship Council, focuses on responsibly managed forests as a way to extend trees’ natural carbon sequestration throughout their lifecycle. FSC’s mission is to promote environmentally appropriate, socially beneficial, and economically viable management of the world’s forests. Two types of certification are offered, Chain of Custody and Forest Management. The certifications provide an honest, transparent look into the path the products take from the forest to a finished FSC® certified product.

FSC® chain of custody certification assures that products sold with an FSC® claim originate from well-managed forests, controlled sources, or reclaimed materials. It includes the multiple stages of the product, including sourcing, processing, trading, and distribution. Certificate holders are also required to implement the FSC® core labor requirements in their operations, ensuring the organization does not partake in forced labor or discrimination in employment. reSAWN holds a Chain of Custody certificate, allowing most reSAWN products to be certified in 1 of 3 categories: FSC® 100%, FSC® Mix, and FSC® Recycled.

Living Building Challenge

The International Living Future Institute is leading the transformation toward a civilization that is socially just, culturally rich, and ecologically restorative. They understand that humanity needs to reconcile its relationship with the natural world and leave it better than it was found. ILFI offers many certifications and challenges to better the built environment, including the Living Building Challenge, Living Product Challenge, Living Community Challenge, and Zero Energy and Zero Carbon certification.

The Living Building Challenge is a philosophy, advocacy tool, and certification program for sustainable buildings. The challenge’s goals focus on resource conservation and sustainable practices in the architecture, design, and construction of all buildings while connecting the communities and their inhabitants to the world surrounding them. These goals can apply to new construction, existing buildings, landscape or infrastructure, and internal projects in the residential and commercial sectors. The program is constantly evolving – the current standard is The Living Building Challenge 4.0. They use a flower with seven petals, or Imperatives, of actionable standards to build and design for a Living Future.

The 7 Petals of The Living Building Challenge
Source: Williams » Class of 1966 Environmental Center » The Living Building Challenge
  • Place: The Place petal focuses on understanding and honoring the place where the built environment stands while honoring, protecting, and enhancing the ecology surrounding the project.
  • Water: The Water petal focuses on an inherent understanding of the value of water – minimizing waste, avoiding pollution, using less, and not using potable water for irrigation to ensure responsible water use.
  • Energy: The Energy petal focuses on renewable energy that helps the building operate in an energy-efficient and pollution-free manner, minimizing carbon emissions related to energy.
  • Health & Happiness: The Health & Happiness petal focuses on creating healthy spaces that allow natural light, healthy air, and a healthy interior environment that benefits the project’s occupants and the nature surrounding it.
  • Materials: The Materials petal focuses on building materials that are non-toxic and ecologically restorative while being transparent about their ingredients. 50% of wood products must be FSC®, salvaged, or harvested on-site either for the purpose of clearing the area for construction or to restore or maintain the continued ecological function of the site. The remainder must be from low-risk sources5. The project must also contain one Declare label product per approximately 2,153 square feet of gross building area.
  • Equity: The Equity petal focuses on creating and nurturing communities that are just and inclusive, enabling all people to prosper and reach their full potential. This includes making the building accessible to all while ensuring that the building is mutually beneficial for its inhabitants and the community it supports.
  • Beauty: The Beauty petal focuses on connecting to nature through biophilic design. A beautiful building starts with people and nature and their symbiotic relationships to place, climate, culture, and community.

As of April 2019, ILFI reported 563 registered Living Building projects in 29 countries. Abodo Vulcan Cladding received the Declare label from the International Living Future Institute, affirming their products are Red List Free, making it an excellent building material choice. reSAWN TIMBER co. is proud to be the exclusive manufacturer and distributor of Abodo thermally modified Vulcan cladding, slats, and decking products in the USA.

VIDEO: Cleaning & Recoating Charred Accoya Exterior Cladding 

By Jocelyn Mahan In CHARRED WOOD, In the Field, Low Maintenance Finishes, Maintenance /   No Comments

In this video & article, reSAWN shows you how to clean & recoat charred exterior siding. The video focuses on IKIGAI which is one of our charred Accoya materials. IKIGAI is first burnt in the Japanese style of shou sugi ban which accentuates the natural grain pattern. It is then brushed to remove most of the charcoal layer and finished with an exterior oil top coat.

Video Transcript: Hi, this is Ryan with reSAWN TIMBER co. ‘s R+D Department. 

Today we’re going to be showing you how to clean an exterior cladding product in preparation for a recoat.

Keep in mind, that Accoya is a modified wood and doesn’t require recoat maintenance. However, if the desire is to get back to that day one color, we do recommend a recoat for aesthetic purposes.

So the first step in this process is knowing when your cladding was installed. So we know – our test board for IKIGAI has been out on our testing rigs. We know this was put outside 3 years ago (1 year of weathering = 3 years of accelerated weathering). So, that falls in the 3-4 year window of when we recommend recoats.

Accelerated Weathering Correlation

Accelerated weathering means exposure of our products facing South on a 45-degree angle. One year of accelerated weathering equals approximately three years of natural weathering.

Visual Inspection of Cladding

The next step would be to visually inspect the product for any kind of damage, fading, mold – things like that. And after taking a look at this, and knowing how long it’s been outside, we’ve decided to do a recoat on this product.

This product here is IKIGAI. This is a shou sugi ban product or a charred Accoya product.

And I think after we clean it and prep it and we get the finish on there, it’ll look just as good as the day it got installed*. So, let’s do that.

NOTE*: Maintenance and recoating guidelines vary by product. Contact reSAWN TIMBER co. for product-specific information.

IKIGAI Accoya – Before Cleaning & Recoat
Ryan Examining IKIGAI
Visual Inspection of Exterior Cladding

Part 1 – Cleaning IKIGAI Accoya Exterior Wood Cladding

  • Step One – dampen the surface with water, using a garden hose if possible.
  • Step Two – apply reSAWN’s ready-to-use exterior wood cleaner using a soft-bristled brush.
    • NOTE: For lighter cleaning, the product can be diluted with water at a ratio of 1:2.
  • Step Three –  scrub the treated area with a soft-bristled brush. That’s a nice soft-bristled brush. Working lengthwise along the wood until it is clean. For stubborn stains, repeating the treatment may be necessary. 
  • Step Four –  rinse thoroughly with water until all of the foam has been washed away.

Let the wood dry for a minimum of 24 hours before starting the recoat process.

Part 2 (Optional) – Recoating IKIGAI Accoya Exterior Wood Cladding

  • Step One –  stir the oil finish provided by reSAWN thoroughly before use.
  • Step Two – once the clean surface is dry, apply a layer of oil finish supplied by reSAWN with a foam pad. Work length-wise across the boards. Maintain a wet edge to prevent any lap marks. 
  • Step Three – wait for 1 to 3 minutes, allowing oil to penetrate. Then buff off traces of excess product with a piece of cloth.
  • Step Four – Let the surface dry for about 24 hours.

NOTE: Complete curing takes place after 7 days.

Cloths that are soaked in oil may spontaneously combust, and must therefore be submerged in water after use.

Accelerated Weather Testing at reSAWN TIMBER co.

At reSAWN, our Research & Development department ensures the quality assurance necessary to specify our exterior cladding products with confidence. Testing begins at the conception of a new product by placing the product on our accelerated weathering rigs. Our R & D team studies the finish performance and quality and structural performance of each product.

Accelerated Weathering is done at our facility in Telford, PA. Telford is located in the southeastern part of Pennsylvania in the Northeastern United States in the humid continental climate zone, with some characteristics of the humid subtropical climate that lies in Delaware and Maryland to the south. A humid continental climate is a climatic region typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold in the northern areas) winters. Precipitation is usually distributed throughout the year. Telford experiences average temperatures of 25 °F to 45 °F in the winter and 65 °F to 85 °F in the summer. The average precipitation per month is around 3.5 inches with an average yearly precipitation of 41 inches. The average relative humidity for the year is 65%. The average UV index ranges from low-moderate in the winter (2-5) to high-very high in the summer (8-9).

Materials are installed facing due South with approx. 8 hours of direct sunlight per day at a 45-degree angle to accelerate weathering. The actual weathering appearance and time frame at your site will be different depending on several factors including climate, altitude, and facing. In general, the acceleration factor is roughly 3:1 and so for example, 1 year of accelerated weather testing can be correlated to roughly 3 years of natural weathering. However, taking into consideration the usual high variation of test results obtained with wood samples and the variations in climate zones, facings, and weather — it is impossible to make an exact correlation to the time associated with weathering at your site.

[3:1 has to be qualified as it relates to the material being installed as vertical cladding in a Southern exposure in the Northern Hemisphere. 3-5 Years for Northern exposure. In both conditions, this assumes full UV Exposure. Cladding blocked by UV exposure will alter these estimated time frames. If reSAWN material is used as roof cladding (specifically 12:12 pitch) it’s a 1:1 correlation.]

At reSAWN TIMBER co. we celebrate and visually leverage wood’s inherent tendency to weather over time by designing modern, high-performance products that are meant to age in place with grace.

Incorporating High-Performance Wooden Slats In Architectural Designs

By Jocelyn Mahan In In the Field, Wooden Slats /  4 No Comments

While vertical and horizontal wood siding and cladding have been used as a building material for more than 10,000 years, a little rotation in woods orientation dramatically transforms how we understand building envelopes. When used as an architectural means of expression, unexpected wood slat assemblies can turn an ordinary project into something refined and special.

Timber screening, which consists of multiple pieces of wooden slats is typically used for exterior & interior walls, ceilings, or as a second layer of a facade and constructed from long, narrow sections of high-performing real wood. Moving beyond timber’s traditional role as cladding or framing material, slats offer various design arrangements. Whether vertically or horizontally placed, they exude an element of style, warmth, and sophistication.

Wooden Slats as a Green Building Material

Concern for the climate and environmental impact is propelling architects and designers to turn to an age-old building material with a new perspective. Since sustainably harvested wooden slats are durable, versatile, easy to work with, and beautiful they are increasingly utilized over traditional, unsustainable building materials. Wood grows naturally using energy from the sun, it’s renewable and recyclable. It is an effective insulator and uses far less energy to produce than concrete or steel. Additionally, technological advancements have introduced high-performance modified woods that perform well in diverse project applications and geographical locations.

What are Modified Timber Slats?

The aim of modified wood is to overcome the shortcomings of standard wood [timber]. The modification process enhances the performance of the wood, resulting in improvements in the longevity of timbers – dimensional stability, decay resistance, reduced water absorption, and less expansion/contraction. In addition, since most advanced modification processes are environmentally friendly, the materials can still be disposed of properly at the end of the product life cycle. 

reSAWN’s modified wood offering for slats includes Accoya, Kebony, and Abodo. Our non-modified offering includes Alaskan Yellow Cedar and Western Red Cedar. The designs used vary greatly in color and aesthetics – from black to light, subtle grays and browns. 

  • 6 Square House – Bridgehampton, NY – reSAWN TIMBER co. IKIGAI Charred Accoya Wood Slats

What is Accoya Wood®?

An example of a chemical modification method in use is Accoya wood. It’s manufactured through the acetylation of plantation-grown Radiata pine. Accoya wood has been thoroughly tested for dimensional stability, durability, paint retention, and in-ground conditions to ensure optimal performance.

All of our Accoya products are FSC® certified and come with a 50-year warranty on the wood when used above ground; a 25-year warranty when used at/below ground level.

  • NOMA – Washington, DC – reSAWN TIMBER co. Custom Charred Accoya Wood Slats

What is Kebony Wood®?

An example of the thermal modification method is Kebony wood. The Kebony technology modifies wood by forming stable, locked-in furan polymers in the wood cell walls. These increase the dimensional stability, as well as durability and hardness, of the wood. This process is based on impregnation with furfuryl alcohol, which is produced from upcycled agricultural crop waste. Kebony offers a 30-year warranty against rot for above-ground use.

      The Importance of Field Mockups for Exterior Wall Cladding Assemblies

      By Jocelyn Mahan In In the Field, Mockup Program /  2 No Comments

      Given rising labor & material costs and ever-expanding lead times, even the smallest element executed incorrectly can have detrimental implications to a project’s budget and schedule. Solid execution is particularly critical for exterior features that safeguard a structure from the elements. That is why field mockups for exterior wall assemblies have become such an essential part of planning during residential and commercial projects.

      Mockups provide architects, designers, contractors, and owners the opportunity to assess an in-person, three-dimensional representation of a design so that functionality, aesthetics, and quality can be evaluated down to the smallest detail.

      The building enclosure (envelope, skin, facade, etc.) represents one of the greatest risk elements of construction. Water penetration, air leakage, and increased energy consumption are common consequences of poorly designed and constructed building enclosure assemblies.

      Exterior wall cladding is the visible and exposed surface of a wall assembly and the primary water-shedding layer. It is subjected to the elements and must be constructed to endure long-term deterioration and weathering.

      Fortunately, a wall surface does not have to be completely waterproof in order to resist rain and snow. It simply needs to be able to prevent water from getting past the surface material and into the rest of the wall assembly. This concept is what led to the development of rainscreen layered wall assemblies – one of the most reliable ways of keeping exterior walls dry or allowing them to dry out when they do get wet. It’s reSAWN’s preferred method.

      Rainscreen assemblies are built on the assumption that water does not move on its own. Rain and snow, the two most common types of water that fall on an exterior wall, are either pushed downward by gravity or pushed sideways by the wind. The airspace behind a building’s cladding or exterior finish has a significant impact on the physical consequences of rain on built environments and their ability to dry after getting wet.

      A rainscreen deploys an outside surface – a rainscreen cladding layer – to break the power of sideways, wind-driven water movement, allowing any water that passes through the microscopic gaps in the surface to lose speed. The majority of water merely bounces off the surface or runs down the side of the building.

      Why Do a Field Mockup for Exterior Wall Assemblies?

      When specifying wood cladding materials for exterior applications, weathering is something that architects, interior designers, and building owners should keep in mind. Since wood is a natural material, when it’s continually exposed to environmental elements such as moisture, sunlight, and wind, the physical attributes of the material change and weather over time. With an exterior wood cladding assembly mockup, specifiers can choose products confidently, knowing that the cladding suits the exact exterior conditions where the structure is being built, by observing how it weathers and moves over time in a project-specific climate.

      Mockups create an opportunity to refine a design approach before the actual fabrication of components begins and before any unresolved or unknown issues are constructed into the building. Once completed, exterior wall assembly mockups serve to establish the technical, quality, and aesthetic standards for the wall cladding and the project. 

      The integrity of an exterior wall assembly depends on the performance of its individual components & systems and the transitions between said systems. By taking the time to construct and test a mockup, architects, designers, and contractors can be sure they have the proper materials, a working assembly, and quality execution.

      Even with today’s photorealistic rendered images through building information modeling (BIM), full-scale mockups do more than a drawing or rendering can.

      Exterior wall system mockups allow project teams to touch, see and interact with the finished product while it’s still early enough to make changes without cost impact. Furthermore, since every structure and location is unique, and there are innumerable building material possibilities available, BIM or computer-aided design (CAD) detailing cannot resolve field-dependent variables the way a full-scale field mockup for exterior wall systems can.

      When done correctly, the construction of a mockup allows a project team to collaboratively work out detailing and compatibility issues that arise during the course of construction, verify the proper function of the intended construction, and apply the results from the process to the project, thereby avoiding costly repeated defects in the completed residential or commercial building.

      Benefits of Field Mockups for Exterior Wall Cladding Assemblies

      • Specify material confidently, knowing that the product suits the exact exterior conditions where the structure is being built.
      • Observe some amount of wood weathering in a project-specific climate.
      • Observe tolerance for wood movement in a project-specific climate. Most wood movement occurs in the first 6-8 months after installation.
      • Understand wood cladding appearance over a larger field of material.
      • Monitor effectiveness in rear ventilation & drainage through assembly details (i.e. rainscreens).
      • Mockups are useful for obtaining approval from stakeholders who may find it difficult to understand drawings and specifications.
      • With a mockup, project teams have the chance to see how the material will perform at the project site prior to full-scale construction.
      • Performance mockups provide assurance that the specified materials will function as required under a variety of extreme climatic conditions.
      • The most seasoned trade partners can benefit from using a exterior wall cladding assembly as a teaching tool to show teams how the work should be done. This reduces the risk of quality issues while improving the speed of construction. 
      • In the interest of sustainability, creating a mockup to to help ensure materials will only have to be installed once, can proactively reduce waste on a construction project.
      • Creating and testing a building enclosure mockup on a small scale, ensures it is done right on a grand scale. It saves project time, money, aggravation, and waste.
