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.

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.

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.

SiOO:X Wood Protection System – Where Technology and Nature Converge

By Jocelyn Mahan In ABODO Wood, Featured In The News, In the Field, Inspiring Designs, Low Maintenance Finishes /  5 No Comments

The natural beauty, durability, and availability of wood have made it one of the world’s oldest and most sustainable building materials. Today, architects and designers use real wood not only in a traditional sense but also in highly imaginative ways – both visually and technically. From an end-user perspective, a common issue with choosing real wood cladding for exterior facades is the perceived ongoing maintenance and uneven weathering on different structure parts.

Uneven Weathering on Uncoated Exterior Wood Cladding

In the last decade, wood finish manufacturers such as SiOO:X Wood Protection have improved the category’s overall design and performance capabilities to solve common building envelope issues. Now there’s a wood cladding finish option that combats weathering and ongoing maintenance issues by taking advantage of several technological advancements.

SiOO:X Wood Protection Logo

The SiOO:X Wood Protection System is a reactive coating system that creates a unique protective barrier to timber. It is designed to minimize the frequency of maintenance when compared to other semi-transparent coatings by creating a surface that becomes more attractive as it ages. SiOO:X mirrors the natural aging process of wood by accelerating the creation of a weathered, silver-grey appearance while giving long-life protection in a completely environmentally friendly way.

This also solves the issue of uneven weathering where some areas fade due to UV exposure, and others don’t. SiOO:X creates a consistent grey tone that mimics the look of weathered wood subjected to years of exposure from exterior elements. With SiOO:X, the wood will resemble a weathered look starting around 10-16 weeks after exterior installation, depending on the area’s climatic conditions.

How Does SiOO:X Work?

SiOO:X is a patented, two-part application silicon technology system. Part one protects and strengthens the wood’s structure, and part two seals and protects the application of part one until the curing process is complete. Once applied SiOOX cures by reacting with carbon dioxide and moisture in the atmosphere to form an insoluble and flexible silica network within the timber surface. The silicon molecules then grow and expand in the cells and around the wood fibers, deep into the wood, creating the network. The formation of the silica network toughens the surface of the timber and forms an effective barrier against moisture, insect attack, and rot. The network fuses the silicon to the wood, strengthening it while creating a unique silicon shield that protects and gives the surface a natural grey finish. SiOO:X wood protection can last up to 15 years.

Abodo Vulcan Cladding in SiOO:X Finish

SiOO:X Wood Protector is applied first – it opens up and penetrates surface fibers in the wood cells where it forms a network of silica crystals, creating a barrier bonded to the surface. An application of SiOO:X Surface Protector is then applied which binds with the Wood Protector and prevents water penetration.

  • Step 1 – The first component, SiOO:X Wood Protector, has tiny silicon molecules that penetrate deep into the wood, where they react and form a solid protective layer over time.
SiOO:X Wood Protector
  • Step 2 – The second component, SiOO:X Surface Protector, acts to seal and protect the first component until it is fully cured, and at the same time forms an inert water-resistant envelope. SiOO:X Surface Protector allows the right amount of moisture to enter, ensuring optimum conditions for the continued process of hardening and mineralization. The result is timber with a beautiful and uniform grey-driftwood appearance, long life protection, and less maintenance overall.
SiOO:X Surface Protector

Is SiOO:X An Environmentally Sound Wood Surface Protector?

Yes. SiOO:X is a water-based and environmentally friendly wood surface protector inspired by how nature protects itself using silicon. Silicon is a naturally occurring mineral found in the natural world. It is in trees, other plants, and humans. Trees and plants absorb silicic acid from the soil which dissolves in water and is then transported in trunks and stalks, precipitating out in the organisms and making them stronger. The same natural process strengthens both teak wood in the rain forests and aspen trees in Swedish forests.

Silicon also preserves wood. This can be seen in trees with petrified wood, which can be found in many locations worldwide. The cellulose in petrified trees is replaced with silicon, protecting them from the weather for millions of years.

What Are The Benefits of Using SiOO:X Wood Protection?

SiOO:X works with wood to protect against:

  • Sunshine and UV rays
  • Rain, frost, and snow
  • Rot
  • Algae and mold
  • Termites other unwanted insects

Advantages of SiOO:X Wood Protection:

  • Low Maintenance – Timber finished with SiOO:X can be regarded as low maintenance and can be left for 5-7 years before considering re-application. The wood will have cured to a naturally weathered appearance when a recoat is suggested in most circumstances. If a weathered appearance is desired, reapplication is not needed nor required.
  • Aesthetics – SiOO:X provides a long-term weathered look in a short period of time while keeping wood protected for years.
  • Penetrating – Non-film-forming coating penetrates into the timber surface and forms a natural protective barrier.
  • Natural – Plant-based ingredients that are safe for people and the environment.
  • Red List Free – Free from Red List chemicals as required by the Living Building Challenge.
  • Water-borne – Only water is needed for clean-up. No solvents are required.
  • Product Performance from Patented technology – SiOO:X carried out extensive tests at their sawmill and production site. In addition to this, they have an independent piece of research underway in conjunction with Napier University’s Centre of Wood Science and Technology. See test results here.

How Long Does It Take For Exterior Wall Cladding To Become Silver-Gray?

Treated wood is initially yellowish-brown and a bit mottled. The curing and bleaching process starts in contact with water, and after 6–12 months, the cladding will begin to have a lovely, even silver-grey tone. The curing and bleaching process then continues for up to 2 years by which time the timber will be a pale, grey driftwood color.

Will all exterior areas cure to the same tone, regardless of exposure to rain and other climatic elements?

Yes, however extremely sheltered areas (for example, under large overhangs) may take longer to turn entirely grey. Sheltered areas can be doused with water periodically to speed up the curing/weathering process. This process can be repeated several times as required.

This color variation evens out quickly and, over a period of 10-16 weeks once exposed to moisture and humidity in the atmosphere, the timber will lighten and develop a uniform appearance as the SiOO:X cures. 

If I order exterior cladding pre-coated in SiOO:X, what color will it be when delivered to a job site?

Immediately after the application of SiOO:X, the color can range from the wood’s original color to a dark brown. The color of the boards may also vary depending on the tannin content.

Advantages of Prefinished Exterior Wood Siding Materials

By Jocelyn Mahan In Wood University /  62 No Comments

Whether you’re an architect, builder, or designer at some point decisions need to be made about the exterior envelope of a built environment.  There are many exterior siding options on the market, such as fiber cement, metal panels, brick, stucco, and stone to name just a few. However, from a durability and sustainability standpoint, there is nothing quite like genuine wood siding. Besides bringing warmth and beauty to the exterior of a home or structure, sustainably harvested timber cladding is renewable, dimensionally stable, and solid. When finished with care and expertise, exterior wood cladding can handle harsh weather conditions with grace while maintaining beauty for years to come.

Why Finish Real Exterior Wood Cladding?

Wood is a natural, sustainable material. As such, when unprotected wood is exposed to outdoor elements like moisture, sunlight, and wind it begins to weather. Without a protective coating or treatment, exposed wood such as siding and trim will change in appearance in a few months or years when compared to the look of day 1 installation. Protecting and maintaining timber cladding is key to keeping it looking at its best for years to come. Finishes protect wood from the elements by preventing UV deterioration, moisture absorption, and staining from mildew and extractives. Finishes also improve the service life of topcoats and are often used to achieve a certain visual aesthetic.

What is Prefinished Exterior Wood Cladding?

Prefinished wood cladding, also known as machine-finished or factory-finished is pre-coated or finished to a certain specification by a manufacturer prior to it being installed at a job site. 

Even for the most experienced painter, it can be difficult to avoid minor on-site mishaps like oversprays, streaks, drips, job site dirt pick-up, or lap marks. Utilizing prefinished wood products provides several advantages over site finishing. When factory finished exterior wood cladding products are specified, it expedites field time and provides a consistent, fully vetted, quality-controlled product that can be installed year-round.

For example, SiOO:X is a premium wood protector that provides a long-term weathered look while providing protection – and can last up to 10+ years. This protection lasts a long time, so maintenance cycles are lessened considerably. In addition to the protective benefits gained, as the mineral silicate cures over time, it will start to turn the timber a beautiful, even silver/greyish tone starting from 10-16 weeks (depending on the timber species the weathering period may vary).

Charred Designs

reSAWN’s CHARRED offering includes modified woods like Accoya and Kebony, Abodo, cypress, cedar, black walnut, reclaimed hemlock, and newly harvested western hemlock. The designs and species used vary greatly in color and aesthetics from a fully charred black to light, subtle gray.

We apply our own interpretation to the ancient Japanese shou sugi ban process and take great pride in designing shou sugi ban products on high-performance modified woods. Modified wood aims 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.

Using modified wood as a base for charring increases the durability of the wood, which makes it an excellent choice for a dimensionally stable option that will perform well when exposed to harsh exterior conditions like snow, sun, and rain. Plus, charcoal stays on the surface of modified wood much better than standard softwood species that will chip over time. Our modern manufacturing techniques allow for a higher production yield and many design variations. 

reSAWN TIMBER co. Philosophy

The reSAWN team works with wood’s natural tendency to grey, not against it. Our prefinished products look beautiful on day one and continue to as nature takes over – with little to no aesthetic maintenance needed depending on aesthetic expectations.

reSAWN TIMBER co.’s Abodo® Vulcan Cladding Compliant for Wildland Urban Interface (WUI) Zones

By Jocelyn Mahan In ABODO Wood, Featured In The News, In the Field, Inspiring Designs, Wood University /  67 No Comments

In an unprecedented reversal of American history the US population is becoming less concentrated in urban areas. Many Americans are moving out of big cities and metropolitan areas en route to the suburbs, exurbs, and rural areas.

As more and more people live in and around forests, grasslands, shrub lands, and other natural areas—places referred to as wildland-urban interface, or WUI zones—problems related to wildfires are exacerbated. There are more wildfires due to human ignition. Wildfires that do occur pose a greater risk to lives and homes, they are hard to fight, and it becomes impossible to let natural fires burn.1National Academy of Sciences Furthermore, the expenses to reduce fire hazards, battle rapidly spreading fires, and protect homes and human lives have risen pointedly in recent decades. 

What is the Wildland Urban Interface (WUI)?

The wildland urban interface consists of geographical areas where human development and infrastructure (e.g., cell towers, schools, water supply facilities, etc.) meet or intermingle with undeveloped wildlands.

They are locations where wildfires have their greatest impacts on people and property. WUI zones are of concern for the public, federal, state, and local governments, so wildfire mitigation and preparedness are necessary when living within WUI zones.

Where is the Wildland Urban Interface Within the US?

Across the United States, wildland-urban interface zones in areas within California, Utah, Arizona and Oregon are experiencing wildfires. California has the most densely packed WUI in the United States.2Rethinking the Wildland-Urban Interface. Currently, they have just over 11.2 million people living in about 4.46 million homes across 6.7 million acres. Six of the twenty largest wildfires in California history were part of the 2020 wildfire season. Five of the new wildfires ranking in the top 10 were all a part of the August 2020 lightning fires. 3California Department of Forestry and Fire Protection (CAL FIRE)

Wildland Urban Interface Zones in the United States

In the Pacific northwest and the lake states, forests are the predominant wildland fuel. In southern California, chaparral brush predominates. The plains states have grass and oak woodlands, New Jersey has Pine Barrens, and the southeast has pine and hardwood forests.4FEMA

Given that wildfires can occur in any wildland area; and the number of acres burned has been increasing; and the number of houses in the WUI is increasing, federal, state, and local government agencies are focusing more on promoting the concept of “fire-adapted” communities. 5USDA A fire adapted community is defined by the United States Forest Service as “a knowledgeable and engaged community in which the awareness and actions of residents regarding infrastructure, buildings, landscaping, and the surrounding ecosystem lessens the need for extensive protection actions and enables the community to safely accept fire as a part of the surrounding landscape.”  6The Fire Adapted Communities Learning Network

Introduction of Wildland Urban Interface Construction Codes

As of January 2008, the 2007 California Building Code (CBC) went into effect along with the inclusion of Wildland Urban Interface building standards. For building products to be used in the (WUI) or State Responsibility Area (SRA), regulations require that building products comply with specific directives. In terms of fire resistance and ignition resistance the primary goal of the WUI code is to hold construction practices to higher standards in the built environment. When a home or structure is designed and built with attention to detail and careful consideration of complaint building materials, it increases the chances of a structure’s survival in a wildfire.

wildland urban interface compliant exterior siding

California Fire Standards for WUI Compliant Exterior Wood Products

According to California Building Code (CBC), the minimum requirement for building envelope components such as siding/cladding is that an exterior wall covering or wall assembly shall comply with one of the following requirements:

  1. Noncombustible material
  2. Ignition-resistant material
  3. Heavy timber exterior wall assembly
  4. Log wall construction assembly
  5. Wall assemblies that have been tested in accordance with the test procedures for a 10-minute direct flame contact exposure test set forth in ASTM E2707 with the conditions of acceptance shown in Section 707A.3.1
  6. Wall assemblies that meet the performance criteria in accordance with the test procedures for a 10-minute direct flame contact exposure test set forth in SFM Standard 12-7A-1.

The benefits of using real wood cladding with wall assemblies that meet the performance criteria set forth in SFM Standard 12-7A-1 are tremendous:

  1. When compared to noncombustible building materials such as steel and masonry, using WUI compliant exterior wood cladding and wall assemblies offer a sustainable, environmentally friendly, carbon neutral solution.
  2. Ignition resistant fire-retardant-treated wood is impregnated with chemicals, so the use of paints, coating, stains or other visually pleasing surface treatments are not an option.
  3. From an architectural and design perspective, WUI compliant exterior wood cladding has many aesthetically pleasing options to suite any project, with a bevy of species and finish options to choose from.
  4. Exterior timber cladding is a versatile, timeless building material that works well in traditional or contemporary architecture.
  5. Not only is real wood recyclable and biodegradable, but it also has strength, toughness, and durability that rivals many other exterior facade options on the market today.

reSAWN TIMBER co.’s Abodo® Vulcan Cladding was recently tested on an exterior wall assembly in accordance with the California Standards Code, Chapter 12-7A, SFM 12-7A-1 (Siding Materials for Exterior Wall Siding and Sheathing). The test simulated wildfire conditions using full size 4′ x 8′ panels that were exposed to a flame of 150 Kw for ten minutes. After, the panels were then observed for 60 minutes to check for further flaming. In order to gather accurate results, the process was repeated three times.

Combustible Components: 5/8 in. thick FlamePro Plywood sheathing, Wrapsheild RS™ Rainscreen 3 mm, Tongue & Groove Abodo Vulcan Exterior Wood Cladding 

A SFM Standard 12-7A-1 pass is achieved if:

  • There is an absence of flame penetration through the wall assembly.
  • There is an absence of glowing combustion on the interior of the assembly after 70 minutes.
  • A test for siding in both a horizontal and vertical orientation is required to be sure of performance.

Utilizing Wood Cladding for Modern, Sustainable Roofing Applications

By Jocelyn Mahan In Product Updates, Wood University /  65 No Comments

For specifiers and building owners who are considering roofing options for a new or existing structure, weighing the pros and cons of building material options is part of a typical build process. Roofing material is highly visible and takes a beating from climatic elements, so choosing a high performing, durable, energy-efficient material is a must on the priority list. 

In the United States and throughout the world, the former and current concerns about climate change and the environmental health of our planet are propelling a large number of homeowners, architects, interior designers, and building owners to search for sustainable, eco-friendly building materials. Due to this much-needed shift in focus, timber cladding products have seen a resurgence and are steadily becoming the material of choice for many buildings and structures that we see in our cities and suburbs today. 

To be clear, cladding is the application of one material over another to provide a skin or layer. In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings. Cladding can be made of a wide range of materials including timber (real wood), metal, brick, vinyl, and composite materials that can include aluminum, blends of cement and recycled polystyrene, wheat/rice straw fibers.[1] When we refer to timber cladding (as it’s commonly referred to in Europe), we’re referring to real wood cladding or as it’s typically known in the United States, exterior siding.

According to Statista: The green building market will be among the fastest-growing industries worldwide. The number of LEED-certified projects in the United States rose from 296 certifications in 2006 up to over 67,200 in 2018.

When it comes to roofing materials, wood cladding that is sustainably harvested is arguably one of the few environmentally-sound roofing options. It’s well-positioned as an eco-friendly alternative to Zinc roofs which have been popularized in recent years.

Real wood is a renewable and recyclable resource. It’s energy-efficient to produce, it performs well over its lifetime, and at the end of the product life cycle, can be disposed of or up-cycled in an environmentally sound, and friendly manner. Plus, timber stores carbon, which plays an important role in reducing carbon emissions outdoors.

The application of exterior wood cladding protects structures from outdoor elements like sun, wind, rain, and snow and helps to maintain the structural integrity of the built environment as well.

The Revival of Real Wood Siding in the Built Environment 

Evidence of the timber cladding revival becomes increasingly obvious when we look to current day exterior and interior designs in the architecture, design, and high-end construction industries. Timber is regarded as the ‘natural’ building material of choice and its use denotes an industry shift to choosing building products that are a good fit for the built environment and our planet.

Examples of timber-clad roofs can be found in areas within northern Europe, like Norway, Sweden, Finland, and beyond. Scandinavian style, vertically laid timber-clad structures have been an eco-friendly, highly-stylized choice for many architectural designs throughout history and in modern applications as well.

The United States has seen an uptick in interest for timber roof cladding and timber clad structures within recent years – especially in progressive areas like the Hudson Valley region of New York state, Los Angeles, California, and the Hamptons on the southeastern end of Long Island. The design typically utilizes the same timber cladding species and finishes on the exterior walls and the roof which creates a bespoke, avant-garde, seamless timber-clad structure. Exterior cladding can be installed in many different configurations and patterns, though timber-clad roofs are typically installed vertically. This style is ideal in modern architectural designs where the slope of the roof is highly considered and regarded as a key focal point.

Weathering Characteristics of Real Wood Roof Cladding

When real wood cladding is exposed to environmental elements such as moisture, sunlight, and wind, the physical attributes of the material will change in appearance in a few months or years, aesthetically evolving over time. Weathering should not be confused with rotted or decayed wood. Wood rot is a form of decay that results from a combination of fungi (microscopic organisms) and moisture. Wood must be consistently damp to foster fungi growth since fungi will not grow on dry wood. On the other hand, weathering is a surface phenomenon that typically only affects a small portion of the surface area. The material will stay almost unaltered for a long time. If modified wood is used for the application, maintenance is not needed to keep a warranty valid with certain manufacturers, like Accoya. The weathering characteristics of real wood cladding create a unique, timeless, and durable roofing material. The benefits and style cannot be recreated or mimicked with any other roofing option on the market today.

Timber Roof Cladding Benefits

  1. Timber cladding is a versatile, timeless building material that works well in traditional or contemporary architecture.
  2. Real wood cladding offers a range of aesthetically pleasing, environmentally friendly species & finish options. 
  3. In most cases, a timber-clad roof does not need to be replaced in its entirety. If damage is found on a wood plank roof, only the damaged boards need to be replaced.
  4. Aside from bringing warmth and beauty to the exterior of a home/structure, timber cladding is dimensionally stable, water-tight, and high performing. It handles harsh weather conditions with grace. 
  5. When it comes to weathering of wood plank roofing, the shift from day-one color to soft greys & light brown tones is an aesthetic by-product to be savored and celebrated. 
  6. When you choose wood cladding for your clients you can guarantee a modern, one-of-a-kind aesthetic that cannot be replicated. Each board works cohesively together, yet each board has its own visual story. 
  7. Wood has the lowest carbon footprint of any conventional building material. It requires less energy to create the finished product than other manufacturing materials such as concrete, metal, or plastic. Plus, most of the energy used comes from renewable biomass like sawdust which is a natural byproduct when timber is sawn and milled.
  8. Due to air pockets in its cellular structure, wood is a natural insulator. Therefore, it is 15 times better than masonry, 400 times better than steel, and 1,770 times better than aluminum, according to Planet Arch.
  9. Not only is wood cladding as a roofing material renewable, recyclable and biodegradable, but it also has strength, toughness, and durability that far exceeds many other roofing options on the market today.

Timber Roof Cladding Product Options

Modified wood brands like Accoya, Kebony & Abodo are great options for timber roof cladding. State-of-the-art wood modification processes enhance the performance of real wood, resulting in improvements in the longevity of timbers – 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.

Selecting clear vertical grain timbers is also an option since straight-grained timber is more dimensionally stable in challenging environmental conditions. WILLIWAW by reSAWN TIMBER co. features Alaskan yellow cedar that is sourced from Alaska to Oregon and intended to provide a high performing, natural material with a weathered aesthetic. In addition to modified wood and Alaskan yellow cedar, reSAWN offers a multitude of high-performing exterior species that include western red cedar and Atlantic white cedar. We also offer charred designs, which are inspired by the Japanese tradition “shou sugi ban.”

Health Benefits of Wood Based Designs in Interior Applications

By Jocelyn Mahan In Featured In The News, Interior Cladding /  1 No Comments

The stay-at-home orders and quarantines in place across the world have many homeowners taking advantage of the additional time at home by jumping into neglected renovations and improvements. According to LikeFolio, consumers mentioning home renovation ideas on social media doubled from normal levels in just two weeks during the start of the pandemic in March 2020.

According to LikeFolio, consumers mentioning home renovation ideas on social media doubled from normal levels in just two weeks during the start of the pandemic in March 2020.

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.

It’s not always feasible or practical to spend more time outdoors, especially in facilities like schools, hospitals, daycare facilities, and workplaces. Fortunately, we can take steps to minimize exposure to indoor toxins by choosing healthier, more sustainable products and building materials. Not only are they better for the environment, but some natural materials and products are proven to have physiological and psychological benefits for humans when brought indoors.

According to many authoritative studies, exposure to wood products indoors 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 to reduce blood pressure, heart rates, and stress levels, whilst improving well being, creativity, cognitive abilities, and the air we breathe.

Planet Ark’s Report; Wood – Housing, Health, Humanity

This report examines the growing body of research showing the range of health and wellbeing benefits of living, working, and learning in environments rich in wooden furnishings and fixtures. “An increasing body of research is beginning to show that being surrounded by wood at home, work or school has positive effects on the body, the brain, and the environment and can even shorten hospital stays through reduced recovery times,” said Chris Philpot, Make it Wood Campaign Manager at Planet Ark.

The report also found:

  • Wood products within a room have been shown to improve indoor air quality by moderating humidity. This effect occurs due to wood absorbing and releasing moisture in order to maintain equilibrium with the surrounding air, known as the equilibrium moisture content. Wood, therefore, absorbs moisture from the air in humid conditions and releases moisture in dry conditions.
  • Residents in aged care facilities interact more with each other when surrounded by wood.
  • Students in classrooms that feature more wood have lower heart rates and stress responses than students in classrooms featuring plastic and metal.
  • Two out of three workers prefer offices with wooden chairs, desks, and blinds over the same office with those items made from plastic.
Students in classrooms that feature more wood have lower heart rates and stress responses than students in classrooms featuring plastic and metal.

According to Planet Ark, the studies show that although many consumers aren’t aware of the health and wellbeing benefits of wood indoors, designers, architects, and contractors are getting on board with sustainable building practices. Sustainable building practices in homes and commercial settings integrate design and development techniques that improve energy, water, and resource efficiency, indoor environmental quality, reduce environmental impacts on the job site; and/or are accredited by a third party to the National Green Building Code, LEED for homes or some other green rating program.

Major Trends in the Use of Wood for Interior and Exterior Use

A convergence of five major trends enhances the case of wood buildings and wood interiors for economic, organizational, and human benefits:

  • Changes in construction codes allow for bigger and larger wooden buildings.
  • The public and big investors are urging the government to take action to combat climate change; while the spreading of green building certifications promotes sustainable development and building upgrades.
  • Employers who are concerned with enhancing the well-being of their employees are incorporating strategies to enhance indoor environmental quality.
  • A growing body of research documents the benefits of green buildings to health and productivity, particularly those using wood construction or finishing.
  • Corporate sustainability approaches tie environmental and human resource priorities more closely together.

A recent 2020 study conducted by Dodge Data & Analytics and the National Association of Home Builders (NAHB) says the percentage of dedicated green single-family home builders has steadily grown from 18% in 2014 to 21% in 2019.

What is Biophilia?

The best proof of the human and organizational benefits of wood is based upon the biophilic properties of wood. Biophilia is the term coined by the Harvard naturalist Dr. Edward O. Wilson to describe what he saw as humanity’s “innate tendency to focus on life and lifelike processes,” and to be drawn toward nature, to feel an affinity for it, a love, a craving. When people come into contact with nature, their neural, physiological, and psychological responses contribute to lower tension, lower blood pressure, more relaxation, positive moods, and increased focus.

toddler-in-white-hoodie-during-daytime

Biophilic design incorporates natural elements into the construction of buildings and their interiors. Wood is one of the few natural resources that can accomplish four important goals simultaneously: reduced carbon emissions; enhanced resilience in the life cycle of a building; improved well-being for the occupants; and increased organizational benefits from having safer, happier, and more efficient workers.

Selecting wood as a construction and interior finishing material is easier than one might think. With many different species to choose from, there are plenty of options that’ll suit one’s construction needs and/or aesthetic desires. Some wood is optimal for insulation, others for acoustics, grain pattern, color, appearance, and others for structural frames, walls, floors, ceilings, and furniture.

  • Abodo Protector Oil: Nine reSAWN TIMBER co. designs (GRAPHITE, PATINA, NERO, STRAW, PEARL, WALNUT, MANUKA, TEAK) are pre-finished with Abodo Protector Oil. Abodo’s Waterborne Protector Oil will nourish and protect external timbers. It uses the latest in waterborne oil technology combining refined plant oils, UV protection, advanced water barrier composition, and an enhanced fungicidal package for superior exterior performance. 
  • SiOO:X One reSAWN TIMBER co. design (SiOO:X) is pre-finished in Sioo:x natural wood coating. SiOO:X is a patented Silicon technology, which silvers off to a beautiful, low maintenance finish. Following application on timbers, Sioo:x cures by reacting with atmospheric carbon dioxide and moisture to form an insoluble and flexible silica network within the timber surface. The formation of this silica network toughens the surface of the timber and forms an effective barrier against insect attack and rot. In addition to the protective benefits gained, as the mineral silicate cures over time it will start to turn the timber a beautifully even silver/greyish tone starting from around 10-16 weeks (depending on the climatic elements). From reSAWN’s experience, boards will initially go darker and then lighten over time. The end result is timber with a consistently weathered, light grey driftwood appearance. 
  • reSAWN’s Exterior Oil Finish: One reSAWN TIMBER co. design (STERLING) is pre-finished with a non-toxic odor-free one-coat oil-based sealer for all types of exterior wood. Most oil-based wood sealers have petroleum solvents that are hazardous. This is the first zero VOC oil-based finish to raise the bar and offer long-lasting wood protection without the off-gassing of toxic chemicals. 

Vulcan cladding’s fine sawn face allows a depth of grain, optimal coating performance, superior beauty, durability, and weathering characteristics. 

ABODO Vulcan Decking

ABODO for reSAWN decking is created from thermally modified New Zealand plantation timber. It’s treated with an organic preservative system that includes water repellent for superior durability.

The thermal modification process gives the material enhanced stability, reduced resin content, and is a beautiful homogeneous brown color. The premium-grade, reeded face has little to no corrosiveness to most metals and can be coated on site.

Benefits of Specifying Vulcan decking

  • Natural Stability – Vulcan Decking is manufactured with a vertical grain orientation, which means the timber has great stability, even in harsh conditions.
  • Easy Fix – Abodo products do not require pre-drilling. That means you can install faster.
  • Forest Stewardship Council (FSC®) Certified – A guarantee that forest products come from responsibly managed sources, including forest management and chain of custody.
  • Red List Free – Free from Red List chemicals as required by the Living Building Challenge.
  • Built to Last Warranty – Vulcan Decking is covered by a 25-year warranty.

 ABODO Decking uses a patented glue lamination for a modern, clean vertical grain orientation. It provides superior weathering characteristics, greater stability, and less surface cracking – this means the wood ages with grace as its left to weather outdoors.

Samples of our ABODO products are available for architects and designers at no cost and shipped via UPS Ground. Click on the button below to explore reSAWN’s complete product offering – sort by species, color, or application.

Benefits of Specifying Pre-Weathered Exterior Wood Cladding

By Jocelyn Mahan In Wood University /  2 No Comments

Wood is a natural, sustainable material. As such, when it’s continually exposed to environmental elements such as moisture, sunlight, and wind the physical attributes of the material changes and aesthetically evolves over time. 

WHAT IS WEATHERING?

Weathering is defined as the chemical and physical changes that take place when timber is exposed to weather. Weathering factors that are responsible for the changes are: moisture (rain, snow, dew, and humidity), oxygen, solar radiation (ultra-violet (UV), visible, and infrared light), and temperature.1William C. Feist: Weathering and the Protection of Wood

It’s important to note that weathering should not be confused with rotted or decayed wood. Wood rot is a form of decay that results from a combination of fungi (microscopic organisms) and moisture. Wood must be consistently damp to foster fungi growth since fungi will not grow on dry wood. On the other hand, weathering is a surface phenomenon that typically only effects a small portion of the surface area. In the absence of decay, wood exposed to the weather can last many years since the performance and durability of the materials are not affected. As such, weathering should not be regarded as a problem, but rather a natural process that needs to be taken into account when planning for the preservation and protection of outdoor wood.

What is Modified Wood?

By Jocelyn Mahan In Wood University /  6

Modified wood is a generic term that describes the application of chemical, physical, or biological methods that are used to alter the cellular structure of the wood. The U.S.D.A. ‘s National Forest Service Library defines modified wood as “wood that is processed by chemical treatment, compression, or other means, with or without heat, to impart permanent properties quite different from those of the original wood.”

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.
