reSAWN TIMBER co.’s offering of Accoya® wood is expanding to include Accoya that has been impregnated with a non-toxic grey pigment for a through body color that is intended to be a living finish that will weather naturally in place and requires no maintenance – OXFORD, MARENGO, and GREY MATTER.
The advantage of these materials is that they are grey from day 1 and can be used to achieve consistent color on all exterior surfaces regardless of facing (north, south, east, west) or application orientation (cladding, roofing, soffits, underside of canopy). This grey color can also be seamlessly carried into the interior walls or ceilings.
WHY SPECIFY ACCOYA?
Accoya is wood, but not as you know it. It is modified timber in which a process called acetylation, a cutting-edge patented technology, enables it to resist rot, defy the elements and stay strong for decades. With warranties starting at 10 years and going up to 50 years, its performance and properties are remarkable. From joinery for the home to bridges submerged in water, Accoya wood is a leading material that stands up to every application challenge – decking, cladding, and more.
WHAT ARE THE BENEFITS OF THROUGH BODY COLOR ACCOYA?
Guaranteed durability backed by warranties:
Commercial Warranty: 10 year warranty on Decking; 50 year warranty on cladding, trim, and millwork
Residential Warranty: 25 year warranty on Decking; 50 year warranty on cladding, trim, and millwork (except in Florida – for Florida commercial warranty length applies)
Beautiful grey color: The day one grey color means no wait time for a naturally grey product. The through body color grey ensures a consistently beautiful appearance from day one.
No maintenance: Due to the through body grey color, OXFORD, MARENGO, and GREY MATTER do not have to be re-oiled regularly or re-colored after scratches.
Barefoot friendly: In addition to Accoya’s durability and dimensional stability, Accoya wood rarely warps and hardly cracks or splinters. OXFORD, when used as decking, will feel soft underfoot in the long term.
WILL OXFORD, MARENGO, AND GREY MATTER STAY GREY?
Through body color Accoya products are colored grey from the surface to the core, requiring less maintenance. These products are grey from day one, so there is no need to wait for the wood to weather or naturally patina. The coloring will stay grey without oiling or re-dying. Since the grey color is all the way through the board, it also means scratches and scrapes are not visible.
WHY SPECIFY reSAWN’s THROUGH BODY COLOR ACCOYA?
We work with woods’ natural tendency to grey, not against it. Our products look beautiful on day one and continue to as nature takes over – with little to no aesthetic maintenance needed. Each board works cohesively together yet each board has its own visual story. The result is modern originality & inherent textural beauty with each and every project.
Samples of our Through Body Color Accoya products are available for architects and designers at no cost and shipped via UPS Ground. Click on the button below to order samples.
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. 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
Timber cladding is a versatile, timeless building material that works well in traditional or contemporary architecture.
Real wood cladding offers a range of aesthetically pleasing, environmentally friendly species & finish options.
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.
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.
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.
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.
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.
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.
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.”

Pre-Finished Vulcan Cladding Options
Vulcan Cladding is available prefinished with Abodo Protector Oil, SiOO:X surface treatment, or reSAWN’s exterior oil finish.
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.

reSAWN TIMBER co. is pleased to announce the addition of 4 rough-sawn weathered ATLANTIC WHITE CEDAR designs to our sought after cedar offering – for exterior cladding and interior wall/ceiling cladding. The new rough-sawn offering includes 4 designs: CHINOOK, FOEHN, OSTRO and SIROCCO.
WHY SPECIFY ATLANTIC WHITE CEDAR
We offer ATLANTIC WHITE CEDAR because of its propensity for resiliency, beauty, and versatility. Its lightweight, straight grain, ease of machining, ease of finishing, low shrinkage, and extreme resistance to decay make it a trusted and elegant option for both interior and exterior applications.
ATLANTIC WHITE CEDAR that is uncoated and exposed to weather over time will develop an attractive silver/gray patina.The rate of that color change depends on climate zones, the orientation of the home/structure and exposure to weather. reSAWN’s finishing process on our pre-weathered ATLANTIC WHITE CEDAR designs solve for wood’s natural propensity to grey out by resembling a weathered look at the time of installation, with little change as it ages in place.
An additional benefit to our pre-weathered designs is the ability to achieve consistent color on all differing exterior exposures and to attain a seamless interior/exterior aesthetic from day one when exterior cladding is brought to the interior (see the BRIZA image below for an example). From the start expect a soft, consistent weathered color and texture that looks natural, appealing and interesting. For interior applications, expect little to no change from the day of installation.
New York City Mayor Bill de Blasio plans to introduce a bill banning new construction of glass skyscrapers as part of his efforts to reduce citywide greenhouse emissions by 30 percent.
In announcing his Green New Deal on Monday, the democratic mayor says all-glass facade skyscrapers are “incredibly inefficient” because so much energy escapes through the glass. He says buildings are the No. 1 cause of greenhouse emissions in New York.
While we prefer to steer clear of the politics of this announcement, it does raise an interesting question of what the future of New York will look like as new building materials are continually being explored.
reSAWN has the pleasure of working with SHoP architects on a conceptual structure using reSAWN’s shou sugi ban charring technique on mass timbers.
Called 475 West 18th, this was a unique research & development project exploring the use of mass-timber construction on a proposed 10-story building in New York City. Ultimately the project did not go through, but the invaluable lessons learned by SHoP and reSAWN are being applied to other innovative wood projects.
Mass-timber also acts to actively sequester carbon (approximately one ton per cubic meter), offering an exciting new path for designers everywhere who seek to meet ambitious sustainability goals.

The partnership comes at an advantageous time when exterior wood siding is continuing to gain popularity for its sustainability, beauty, and performance standards. reSAWN’s five current Kebony® designs take full advantage of the chemically modified wood’s durability, and incorporate the aesthetic value provided by the company’s CHARRED and weathered finishing techniques…
DURABILITY–Western red cedar is a naturally durable softwood that creates extractives (Thujaplicans and Phenolics) that ward off decay caused by insects, water infiltration, and fungi. The extractives increase with age leading to a longer lasting product life cycle–especially in exterior applications.
DIMENSIONAL STABILITY–WRC has a very low shrinkage factor and is largely superior to all other coniferous softwoods in its resistance to warping, checking, and twisting.
THERMAL CONDUCTIVITY–WRC’s low density gives it a high thermal insulating value because it contains a high proportion of cell cavities. In dry wood, these cavities are filled with air which is one of the best known thermal insulators. The R value is 1.35 per inch of thickness.
FIRE RESISTANCE–reSAWN’s CHARRED CEDAR has a Flame Spread Index of 40 and a Smoke Developed Index of 140 to give it a Class B Rating. CHARRED CEDAR can be fire treated to Class A for interior projects.
