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.

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).

Accelerated Weather Testing at reSAWN TIMBER co.

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.

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, 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

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.

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.

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.

Wall System: Exterior Wall Assembly
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.

reSAWN TIMBER co.’s Abodo Vulcan Cladding is WUI Compliant

reSAWN TIMBER co.’s Abodo Vulcan cladding passed the test for both horizontal and vertical orientations for upcoming inclusion in the WUI Products Listing. A copy of the test results can be found here. The result? Abodo Vulcan cladding is now a compliant wildland urban interface building material.
