Natural wood possesses inherent beauty and is frequently incorporated into construction designs for its aesthetic appeal. However, wood is a natural material susceptible to degradation due to climatic elements, moisture, and UV rays. To preserve natural wood’s integrity and longevity, the application of a protective topcoat is a standard practice for all timber building materials.
In the realm of wood protection, SiOO:X stands out as a revolutionary solution that provides timber with a long-lasting shield against the outside elements and delivers a captivating aesthetic transformation over time. Unlike conventional wood treatments that create a protective seal on the surface, SiOO:X penetrates deep into the wood fibers, forming a shield that enhances the durability and longevity from within.
SiOO:X leverages the natural environment and wood’s characteristics to gradually cure wood over one to three years. This unique curing process results in a protection system that imitates wood’s natural protective layer. The curing process also triggers a gradual color transformation within a short timeframe, mimicking the authentic weathering effect seen in natural wood.

Curing with Nature SiOO:X is crafted to work with nature. The curing process is intricately tied to the specific climatic environment where the wood cladding resides. The rate of change is often attributed environmental factors. Sunlight, rain, wind, and humidity are all factors that could affect the curing process*. Surfaces shielded from direct sunlight and harsh weather conditions, such as soffits or non-exposed walls, may undergo a slower rate of curing and color evolution. In contrast, the cladding that is fully exposed experiences more significant fluctuations.
Understanding the Curing Process SiOO:X Wood Protector holds a unique silicon and potassium formulation that reacts with moisture and carbon dioxide. This chemical reaction forms a protective barrier within the timber. SiOO:X’s chemical reaction can occur independently of sunlight, ensuring consistent and reliable performance regardless of weather conditions over time. It creates a long-lasting shield against moisture, and UV rays.
The Evolution of Color As the curing process progresses, the timber undergoes a remarkable transformation of color. The wood starts out in its natural coloration before gradually transitioning to a light whitewash tone, typically within six – twelve months of application. This initial phase represents the activation of SiOO:X’s protective properties that penetrate deep into the wood fibers. The timber gradually darkens to mid-gray ‘weathered’ tones, acquiring a timeless patina that adds depth and character to the wood surface. Exposed surfaces may undergo a more rapid color evolution than non-exposed walls. However, despite the differences in the rate of color evolution, the aesthetic outcome will be consistent across all surfaces over time.
Advantages Over Traditional Coatings SiOO:X’s natural curing process offers several advantages over traditional coatings, particularly when it comes to durability, aesthetics, and environmental sustainability. Conventional wood protector coatings’ efficiency diminishes over time with exposure to the sun, leading to fade in color and less protection against wear and tear. On the contrary, SiOO:X works with the environment and delivers a natural color evolution. Wood treated with SiOO:X offers long-lasting protection and reduces the need for frequent reapplications, conserving resources and reducing maintenance costs in the long run.
An Eco-Conscious Formula With a clear focus on sustainability and eco-friendliness, SiOO:X is engineered with a low VOC (volatile organic compound) formulation. It minimizes environmental impact while ensuring safety for users and our planet. By enhancing the longevity of wood, the lifespan of wooden structures is extended, contributing to waste reduction in the long run. Unlike other wood treatments that may leach harmful chemicals into the soil or waterways, SiOO:X is biodegradable and poses no risk to ecosystems.

*In case of problems with black spores the SiOO:X system creates a barrier that prevents algae and spores from penetrating the wood. Because SiOO:X does not contain any strong toxins it cannot prevent black spores from settling on the surface. Periods of rain or damp weather are especially favorable for these airborne spores, which can often be found on wood surfaces that are in the shade or exposed to the weather. Black spores need nutrients to grow and they get these from natural sugars in the wood. These substances are leached out of the wood in the first 1–4 years. The presence of black spores also decreases as the SiOO:X silicon shield matures and gets stronger. For a full Care & Maintenance Guide, click here.
Earth Day 2024 spotlights the theme “Planet vs. Plastics,” drawing attention to the pervasive use of plastic and its detrimental effects on the environment. While plastic remains a staple material in numerous industries, its profound negative impacts on Mother Earth are undeniable.

In the world of architectural design and construction, the choice of building materials plays a pivotal role, influencing the aesthetic appeal and a structure’s sustainable commitment and functional aspects. With the growing emphasis on sustainability and reducing carbon emissions, staying well-informed and possessing the knowledge to design and build with sustainable materials has become more crucial by the day.
According to The Institution of Structural Engineers, the building and construction industry is responsible for 40% of annual carbon dioxide emissions. Choosing appropriate building materials represents the first step in decarbonizing the building and construction sectors. The global popularity of using renewable, biogenic building materials is rising due to high sustainability awareness. A building product’s embodied carbon accounts for all the carbon emissions released throughout the product’s entire supply chain and life cycle. When opting for a building material, consideration should be given to all factors influencing carbon emissions throughout its entire life span.
Beginning as raw material, wood functions as a carbon sink, actively storing carbon dioxide from the environment. Contrary to the prevailing belief that harvesting trees disrupts the ecosystem and diminishes the photosynthesis process, wood remains a carbon sink even after being harvested. The regrowth of trees following harvest plays a crucial role in sustaining and balancing the ecosystem. Throughout the regrowth process, trees absorb carbon from the atmosphere. In addition, when forestry is managed sustainably with a focus on biodiversity, the diversity of the ecosystem provides an environment for microorganisms to thrive. These microorganisms actively contribute to soil restoration and enhance the productivity of emerging forests. Consequently, the soil gains capacity as a carbon store, effectively mitigating carbon dioxide emissions into the atmosphere.
A significant factor influencing the embodied carbon of a building product is transportation. Arup’s Embodied Carbon report highlights that the logistics involved in transporting raw materials to the factory contribute to 8-10% of the embodied carbon while transporting the finished product to the construction site accounts for 50-55%. The sourcing of materials holds paramount importance in determining the embodied carbon of building materials, impacting manufacturers and the decisions of architects and builders.
Timber stands out as one of the most natural construction materials, boasting lower carbon intensity in manufacturing, transportation, and construction than synthetic or man-made alternatives.

For centuries wood has been a popular and traditional material for various applications and its timeless appeal continues to endure in modern times. Its versatility, sustainability, and aesthetic qualities make it a preferred choice for a wide range of building uses, from commercial to residential applications.
As the popularity of wood continues to grow in the construction and design industry, manufacturers are actively developing new technologies to expand the product offerings. This effort caters to the increasing demand and aims to elevate the performance and sustainability of wood in construction and design applications. Among these methods, thermal modification stands out as a process that transforms wood into a material with improved durability, stability, and aesthetic qualities. This article delves into the various aspects of thermally modified wood, exploring the process and the remarkable benefits it brings.
Thermal modification is an eco-friendly process that involves altering wood using heat energy, omitting the use of additional chemicals. The heart of the process lies in the thermal modification itself. Wood undergoes controlled heating in an oxygen-deprived environment, while gradually raising the heat to the desired temperature. Precise control is exercised to ensure uniform heating throughout the material. This process induces structural changes within the wood, enhancing its properties without risking combustion.
The wood is maintained at an elevated temperature for a specified duration, allowing the thermal modification to permeate its cellular structure. This cooking phase is pivotal for achieving the desired physical and chemical transformations. The controlled application of elevated temperatures in the absence of oxygen leads to several changes in the cellular components of wood, including hemicellulose, cellulose, and lignin—which are three major components that contribute to the overall mechanical properties of wood.
Hemicellulose Decomposition Hemicellulose, a polymer comprised of sugars found in timber, constitutes a significant portion of wood, accounting for 20-35% of its dry weight. It plays a crucial role in moisture absorption and facilitates cross-linking among cellular components. During thermal modification, hemicellulose undergoes decomposition, leading to a decrease in its content. This process releases water vapor and other volatile compounds from the timber. The reduced hemicellulose content decreases the timber’s capacity to absorb and release moisture, thereby improving its overall stability.
Cellulose Crystallinity Cellulose, a fibrous structure serving as the primary constituent of wood fiber, plays a pivotal role in enhancing the strength and rigidity of wood. The crystalline regions of cellulose are well-organized and tightly packed. The degree of cellulose crystallinity in wood influences the wood’s physical properties, such as strength and stiffness. The heat treatment causes the cellulose chains to become more ordered and crystalline, increasing its stiffness. This alteration contributes to improved dimensional stability and reduced susceptibility to swelling and shrinking when exposed to changes in moisture levels.
Lignin Modification Lignin is a complex polymer that holds cellulose fibers together. It acts as a binding substance and provides structural support and rigidity to wood. At higher temperatures during thermal modification, lignin depolymerizes and breaks down into smaller fragments. The heat energy then redistributes and recondenses these broken lignin fragments. The reorganization of these fragments can contribute to an increase in lignin content, resulting in altered characteristics such as improved dimensional stability.
Lignin is the primary contributor to the natural brown color of wood. Various wood processing methods can modify or eliminate lignin content, thereby influencing the wood’s color. Thermal modification tends to contribute to the enhanced coloration of the wood, often resulting in a darker and more uniform appearance.
Cooling Phase Following the thermal modification, a carefully managed cooling phase follows to prevent abrupt temperature changes that could compromise the integrity of the modified wood. By managing the cooling phase correctly, the risk of structural damage to the wood is minimized. Slow cooling helps prevent surface irregularities, such as warping or cupping, which might occur if the wood experiences sudden temperature fluctuations.
In summary, thermal modification process changes the cellular characteristics and interaction among hemicellulose, cellulose, and lignin. These alterations enhance the mechanical properties of the wood, resulting in improved dimensional stability, reduced susceptibility to moisture absorption, and increased resistance to decay.
Thermally Modified Wood Cladding Thermally modified wood has gained significant attention in recent years as an excellent option for wood cladding. The result is a material with enhanced durability, stability, and resistance to decay, making it particularly well-suited for exterior applications.
SylvaTM and Abodo® are two examples of wood species that undergo thermal modification to enhance their performance as cladding materials.
Sylva is created from North American Red Oak, known for its attractive grain patterns and warm, reddish-brown hues. When thermally modified, it not only retains these aesthetic qualities but also gains increased resistance to decay, insects, and other environmental factors. This makes it an excellent choice for exterior cladding, where it can provide both visual appeal and long-term durability.
Abodo Vulcan thermally modified wood cladding is created from New Zealand plantation timber. The thermal modification process gives Vulcan cladding superior stability and reduced resin content. It’s naturally durable so the timber doesn’t require any chemical preservatives, and has a beautiful, consistent brown tone.
The versatility of thermally modified wood and its eco-friendly attributes establish it as a compelling choice for building materials across various applications, spanning from interior to exterior and encompassing both residential and commercial settings. As the building industry seeks sustainable and high-performance materials, the journey into the world of thermally modified wood opens doors to innovation and a more resilient future for wood-based products.

Hey guys, Scott Stevens here with reSAWN TIMBER co. We’re here in Bridgehampton, NY, looking at the Six Square House designed by Young Projects. This home is 3,500 sq.ft. and sits on about two acres of land. Construction was finished in 2020, and we’re visiting three years later to observe how the wood siding and wood roof cladding have performed and weathered over time.
This project utilizes our IKIGAI product, which is produced on Accoya®. Accoya is an exceptionally high-performing modified wood, backed by a 50-year warranty against rot and decay when used above ground (25 years in ground or freshwater). It also offers remarkable dimensional stability, making it a low-maintenance material for your home and this specific finish. IKIGAI is designed to naturally and consistently weather over time.
For this particular application, the architect designed a two and half inch slat in your more traditional open joint rainscreen. What this rainscreen does is that it separates the siding from the sheathing to promote 360 airflow and rear water drainage. The benefit of that is to allow for the wood to fully breathe and dry out. Which adds to the longevity of the material.
Another interesting detail is that they panelized the installation so they were able to blind fasten from behind and hang the panels on the building to ensure a secure fastening so the wood isn’t moving or going anywhere. If you take a closer look at the wood roof cladding down to the siding, there’s a really nice waterfall edge that allows for actual water to sheath down, but also just a really clean detail well executed by the installer as well to keep those crisp, clean lines that the architect intended.
After three years of weathering, it’s evident that IKIGAI is evolving and weathering as it’s intended to do. Lightening up and fading over time to that really quintessential coastal gray color. Due to Accoya’s modification process, there’s no need to reapply the finish. Although, it is always good to do so. Freshen it up and you can get back to that original day one color over time.
We want to shout out Young Projects for not only specifying our material, but designing such a beautiful project that showcases it along with all the other materials on the project.
If you’re very interested in receiving samples of IKIGAI or any of reSAWN’s other product offerings, feel free to reach out and we’ll connect you with the Specification Consultant in your area to help you select the right product for your project.

The high-performing product aged gracefully after three years of installation and will continue to do so due to Accoya® wood’s extreme durability. We appreciate Spire Builders for specifying our product for this project and look forward to continuing our partnership in the future.
NIGIRI – FSC-Certified, Shou Sugi Ban Accoya® wood can be used for interior or exterior wall cladding. NIGIRI is finished with a grey topcoat designed to protect the wall cladding as it naturally weathers over time. reSAWN’s award-winning charring technique adds depth and dimension to Accoya’s natural grain pattern.
Architects and designers can request complimentary Accoya samples to assist in your project decisions.
Hey, I’m John Marley from Spire Builders. I’m here to give you a tour of one of our custom home projects in Delaware County, PA.
This is a large, modern house with about 18,000 sq.ft. of residential space. It’s built with a commercial-grade steel structure, which weighs about 40 tons. The steel structure is a major component of the house, as you can see in the catwalk area. It was important to get the foundation and steel structure as precise as possible, so we used shop drawings to plan everything out in advance.
Once the steel structure was in place, the framers took over. With modern houses, you have to think about every single detail from the framing stage all the way down to the finishing stage, because it could affect things later on.
This house has a lot of challenges that actually make it really unique. For example, we’re building some of the components out of order. We’re installing some of the drywall before we finish other installations. Then, once the drywall is in place, we’re starting on the flooring and trim. This is a bit of a backward way to build, but it’s necessary for this particular house.
All projects start with good drawings and the architect for this project had a very detailed set. We worked out a lot of the details in the mock-up process, but the architect was able to start specifying where he wanted the start corner and other things like that.
We have incorporated a unique and interesting design feature for the window structure. We have cross-section views that provide a detailed look at the construction. In these views, you can see the siding, concealed gutter system, and the Knight Wall system, which plays a vital role in supporting and securing all the elements of the window structure.
Even better, the cross-section views show that the stone and the siding are all in the same plane. This is because the Knight Wall system impacts everything.
We are working with the TBD architects in New York City. You (reSAWN TIMBER co.) introduced them to some of your materials. We narrowed down our choices to the NIGIRI Accoya® Shou Sugi Ban product which presents a dark grey tone and will keep that consistent color throughout its lifetime.
Accoya® wood is a radiata pine that is chemically modified. It is a modified timber in which a process is called acetylation, a cutting-edge patented technology that enables it to resist rot and stays strong for decades. It has a 50-year rot warranty above grade and a 25-year rot warranty at or below grade.

That was a major deciding factor for the client. The client wanted a material that was both low-maintenance and long-lasting. They wanted something that would not require a lot of upkeep, but that would also age and weather gracefully.
The NIGIRI cladding material used is a 1 x 4 board, measuring three and one-half inches in width and three-quarters of an inch in thickness. It features an open-joint design with square corners.
The window jambs run all the way out to the face of the siding material. They are finished on three sides, with the back sides pre-sealed. That extends all the way out to the face, so that way everything is flush.
The window sill has a separate profile that looks very similar. It has a slight pitch and even has a routed groove on the bottom to drain water and moisture away from the sill instead of letting it run back around to the other side of the sill.
We also included an open joint that continues all the way around the window units and in between all the siding.
During the mid-construction phase, you can see where the Knight Wall and window trim have been installed. This process starts at the framing stage, where we used a variety of products, including Green Zip and Benjamin Updike InvisiWrap.
Green Zip is typically used for roof applications, but it can also be used as an exterior weather barrier. However, because the open joint siding cannot rely on this as its facade, we use InvisiWrap, a black wrap that can withstand open joint cladding. InvisiWrap has a 365-day exposure rating and can handle up to two-inch open joint gaps, which is perfectly in line with their warranty. The backside of this product is like a diaper in that it allows moisture to pass through it, but not through the face of it. This means that it acts as an extra raincoat, keeping moisture out while still allowing it to escape.
The next component of this project was the Knight Wall system. I specified this system because I had concerns about the architect’s original plan to use a wood frame structure that would be painted black to hide everything. I was worried about water and rot causing the substructure to fall apart before the siding, which would void the 50-year warranty.
I was able to find a commercial system that is typically used for exterior insulation. This system uses wall clips and long screws to attach the siding system to the frame, which raises the siding off the wall by six inches. This is done for a few reasons, but it is primarily used for exterior insulation.
The rails that we use can be coated with black paint, so we made sure to get them with that coating. This ensures that the silver siding will be visible, and it even has a soft coating to protect projects in coastal environments.
The architect wanted a deeper window jamb, which is why the Knight Wall system was used. This system creates a more visually appealing exterior, and it also allows for a hidden gutter detail and a flush installation with the stonework. The Knight Wall system also helps hide structural components, which makes for a more seamless and aesthetically pleasing finish. It is really unique and it worked out really well for this project.
With the open joint design, a significant amount of flashing is required. Traditionally, regular head flashing is used, but for this project, we opted for a zinc-coated copper flashing instead of the traditional lead-coated copper. We employed a double-head flashing profile, which effectively directs water and any debris away from the house.
To ensure a watertight envelope penetration system, we utilized Quick Flash Units. There are various penetrations, such as outlets, hose bibs, electrical boxes, and even camera wires. The open joint system demands thorough attention to detail; nothing can be overlooked.
The siding material is pre-finished on all sides, but all cuts must be glued and sealed. We use a PPG stain that reSAWN TIMBER recommended, and we apply it with little roller applicators. The cuts are not visible here because they are all butt jointed. However, even butt joints need to be pre-sealed to prevent any issues. I actually tested not sealing the cuts, and it didn’t affect the finish at all. However, we sealed every cut to be on the safe side.
The hidden gutter design was originally introduced to the architect, who drafted the siding and spaced out the gutter detail. It was up to us to make it a reality. The Knight Wall system actually came after the fact, because they had originally drawn a wood framing system that would actually hold the siding. This would have to be black, and there were concerns that it would rot out. We were even going to have to notch out some of the pipes to get them back into the structure. By using the Knight Wall system, we were able to hide a lot of those pipes behind the structure.
Behind this siding piece is the hidden gutter. There is a drop point, and the pipe runs behind the siding system and stubs out to a drain point. We would not be able to do this with a normal system. It is pretty cool that we are able to run the piping behind the rails and hide everything.
The siding material alone is very custom, but one thing that was even more custom was the window jambs. We had everything drawn up and signed off on, and I was even able to provide a profile for the sill. They were able to completely custom-make all of the profiles for us, which was awesome. We would not have been able to achieve the same look without having everything pre-finished to that profile.
We also had very custom exterior doors made at a later date. We milled the raw material to our specifications and then sent it back to reSAWN TIMBER to be finished. This ensured that the doors would match the siding exactly.
The window jamb material had to be specified exactly. The siding system is six inches, and we know that the flanges tend to feather things out a little bit. So I specified the jamb material at five and three-quarters of an inch. This gave us a little bit of flexibility.
So far, we haven’t had to rip any jamb material down. We did order a few extra wide siding boards. In tight little areas, we had to rip it a little bit on site. The edge was then pre-sealed. In certain areas, we might need three and three-quarters or close to four inches. Having those wider boards will actually help resolve those issues.
There are a few different corner details that were done for this project. The architect wanted a simple lap joint, but each corner is being handled a little bit differently.
We measure from ten feet away to ensure that the board lap looks consistent from all angles. For example, we might have to face a board lap forwards or place it on its side, depending on the view. We had to consider the porch area, for instance. They will want to see more of a full board on that side, as opposed to this side, where you can’t see it from here unless you’re 30 feet down below. Even though it’s a simple corner detail, every single corner on the house is thoroughly thought out.
This house has a mixture of cedar and flat roofs structure. The cladding is able to touch grade, but we left a small reveal of about a quarter of an inch along the E-vent’s.
On the side of the house, we’re able to have a drip cap with the gable window. This will allow the siding to tuck up and hide, and be protected.
In areas where we have a flat roof, we’re able to run the siding down. Our deck system ended up butting into that structure and hiding the edge of those boards.
With a 50-year rot warranty, the cladding can touch grade even if it is touching the roof structure. Some materials, like fiber cement siding, require an inch and a half to two inches of exposure to prevent moisture from breaking down the material. However, this material does not require that.
With the 4 x 1 boards, we were able to use a fastener every 24 inches because that is a specification for the Knight Wall. A system like this would typically hold 22 pounds per square foot, and the rails would be spaced 12 inches apart. This is similar to what is required for a stone veneer. However, this system worked better for this project.
We are using a single fine-trim stainless, self-tapping screw for the metal rail system. Even though it is a self-tapper, we are still pre-drilling to prevent the boards from pushing out.
We considered using a Simpson stainless self-drilling trim screw that matches the siding, but the architect was concerned that it would stand out over time. Stainless steel is tried and true, and it looks the same pretty much all year and it has a high resistance to rust.
We use two different sizes of screws for the jambs and the siding. The shorter screw is one inch and a quarter long, and the longer screw is two and a half inches long. The jamb material is one and a half inches thick, and the siding material is three-quarters of an inch thick.
The project started with a mockup. I built the mockup for a couple of reasons. First, I wanted the client to make an informed decision about the products we would use based on their performance and appearance. Second, I wanted to create an instruction booklet for the installation. I took step-by-step pictures of the installation and put them together in a bid packet. This way, all of the subs who were bidding on the project would have the same information. It also helped me to select the right contractor. Some subs turned down the project because it was too much or too involved.
The mockup included reSAWN TIMBER co.’s WABI SABI and NIGIRI exterior siding. We also tried out 1 x 6 and 1 x 4 boards. The client ultimately went with the 1 x 4 boards. The mockup also allowed us to see two different types of stone and the hidden gutter detail.
The mockup has been up for over a year and NIGIRI looks almost exactly the same as it did on day one. The WABI SABI cladding has faded out a bit, which is how it naturally weathers. However, the client preferred the darker tone of NIGIRI and how it stays consistent over time.
The stainless steel fasteners will eventually match the color of the siding, as the siding darkens over time. We used two screws per board in some areas, but with Accoya’s specifications, we can actually use one screw per board. This material has very little expansion or contraction.
The siding was installed with a three-sixteenths of an inch open joint, and remarkably, there has been no movement whatsoever. This speaks to the impressive stability of the material. Even the boards that were left unsealed on the underside remain undamaged, showcasing the remarkable durability of this natural wood material.
Three Years Later
After three years, we revisited this residence with NIGIRI siding, an Accoya® material that’s been charred and stained. The siding has impressively weathered without any signs of wear, and it has demanded no maintenance or cleaning. The most demanding aspect of the project was constructing the garage doors and exterior door. We had to mill the material according to the door specifications before relying on reSAWN TIMBER to finish it flawlessly.

HISTORY OF MUSHROOM WOOD
Otherwise known as hemlock reclaimed wood, mushroom wood has an inspiring and historical sustainability story attached to its derivation. This name is a bit misleading since the wood is not actually made from mushrooms. This wood is used to line the boxes of mushroom crops at mushroom growing facilities today and as far back in history as 1896.
WHAT IS MUSHROOM WOOD?
The wood’s unique character is crafted by nature through a process called fungiculture. During the mushroom growth cycle, the bin wood is exposed to years of acid laden sustainable compost, moisture, and abrasion. Those enzymes digest and gradually wear away the fibers in the top layer of softwood. Once the mushrooms are harvested and the wood is sorted and cleaned, the hardy, durable wood left behind displays a deep, hyper-textured, weathered, one of a kind earthy-caramel patina. Light and shadows dance throughout its rough-grained surface.
