In this video & article, we discuss reSAWN’s Accoya modified wood offering which is prefinished with a waterborne exterior oil. Our one-coat (1C) and two-coat (2C) product offerings provide specifiers with the choice of a more saturated color if desired.
1C Option – Finished with 1 Coat
‘1C’ denotes Accoya wood that is prefinished with one coat of our proprietary exterior oil in the factory. There is no need to apply a second coat of finish post-install.
2C Option – Finished with 2 Coats
‘2C’ denotes Accoya wood that is prefinished with one coat of our proprietary exterior oil in the factory AND will require the installer to apply a second coat of finish post-install. This finish will be included on the sales order and shipped with the materials. Applying a second coat of finish post-install will further saturate the initial color of the cladding and extend the duration of the deeper color.
The video focuses on RAILAY 1C and RAILAY 2C, two of reSAWN’s Accoya wood products with a waterborne exterior oil.
Video Transcript:
Hi, I’m Diane with reSAWN TIMBER, and I’m here today to talk to you about several of our Accoya products that are available with 1C or 2C exterior finish. 1C indicates Accoya is prefinished with one of our exterior oils in the factory, and this does not require a second coat. 2C indicates Accoya is prefinished with one of our exterior oils in the factory, which will require a second coat onsite by the installer.
The big difference between 1C and 2C is the color saturation on day one and as it weathers over time. Applying a second coat of Accoya does enhance the initial color of the exterior cladding and it extends the life of that deeper color over time. However, if you choose not to apply that second coat of finish, that can be a cost savings for your project.
I’m here at the factory in Pennsylvania and we do testing of our own products outside on our weathering rigs. We test for aesthetics and performance. So here are two examples. This is RAILAY 1C and RAILAY 2C – these have been outside on our weathering rigs since September 2021. That is 10 months of accelerated weathering. It’s considered accelerated weathering because it’s on our rigs on a 45 degree angle facing due South.

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

What are the benefits of Accoya wood?
Performance: Tried and tested in the USA. Accoya wood is stable, water and rot-resistant, and comes with a warranty. Accoya wood is thoroughly tested and designed to perform with minimal movement (swell/shrink/distort). Accoya is indigestible by various insects, including termites, resulting in an effective barrier. With a 50-year above-ground and 25-year below-ground and freshwater warranty, Accoya wood can be specified with confidence and enjoyed for decades.
Finish: reSAWN’s carefully crafted Accoya products are thoroughly vetted and tested via reSAWN’s research and development processes to test the aesthetics and performance of the wood in addition to how it weathers. Materials will arrive on-site prefinished, with the option to apply a second coat if desired. Our proprietary finishing process combined with Accoya wood provides a beautiful, low-maintenance exterior siding option.
Sustainability: Sustainability is at the core of Accoya’s business and is part of the entire life cycle of the material, including sourcing, production, and recycling at the end of life. Accoya wood products are FSC® certified, have a low carbon footprint, and are non-toxic to people, pets, and the environment. Accoya wood is the only construction material to achieve Cradle to Cradle Platinum Certification™ for Material Health. Accoya wood siding specifications have a minimal environmental impact.

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

Does Accoya wood require a lot of maintenance?
Not only is Accoya’s durability proven, but it has also been shown to retain its appearance, requiring much less frequent maintenance than other wood species. Since Accoya wood undergoes the acetylation modification process, it requires little to no maintenance. The modification process enhances the performance of Accoya wood, providing outstanding dimensional stability that results in lower maintenance frequency and therefore less coating over the lifetime of the product.
Accoya wood doesn’t require recoat maintenance. However, if the desire is to get back to that day one color, we do recommend a recoat for aesthetic purposes. Maintenance and recoating guidelines vary by product. Contact reSAWN TIMBER co. for product-specific information.
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.
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.
OXFORD Through Body Color on Accoya Decking
WHAT ARE THE BENEFITS OF THROUGH BODY COLOR ACCOYA?
Guaranteed durability backed by warranties:
Commercial Warranty: 10 year warranty on Decking; 50 year warranty on cladding, trim, and millwork
Residential Warranty: 25 year warranty on Decking; 50 year warranty on cladding, trim, and millwork (except in Florida – for Florida commercial warranty length applies)
Beautiful grey color: The day one grey color means no wait time for a naturally grey product. The through body color grey ensures a consistently beautiful appearance from day one.
No maintenance: Due to the through body grey color, OXFORD, MARENGO, and GREY MATTER do not have to be re-oiled regularly or re-colored after scratches.
Barefoot friendly: In addition to Accoya’s durability and dimensional stability, Accoya wood rarely warps and hardly cracks or splinters. OXFORD, when used as decking, will feel soft underfoot in the long term.
OXFORD Through Body Color on Accoya Decking & Pool Deck Surround
WILL OXFORD, MARENGO, AND GREY MATTER STAY GREY?
Through body color Accoya products are colored grey from the surface to the core, requiring less maintenance. These products are grey from day one, so there is no need to wait for the wood to weather or naturally patina. The coloring will stay grey without oiling or re-dying. Since the grey color is all the way through the board, it also means scratches and scrapes are not visible.
WHY SPECIFY reSAWN’s THROUGH BODY COLOR ACCOYA?
We work with woods’ natural tendency to grey, not against it. Our products look beautiful on day one and continue to as nature takes over – with little to no aesthetic maintenance needed. Each board works cohesively together yet each board has its own visual story. The result is modern originality & inherent textural beauty with each and every project.

Using sustainable building materials in the built environment is a top priority now, more than ever. Building and designing a structure in the modern era should include consideration for the long-lasting impact of all facets of the design and build process. Due to this shift in focus on sustainable building materials, wood flooring and exterior wood cladding are frequently sought out as sustainable building materials to specify. In addition to its environmental and sustainability attributes, wood has multiple benefits, including its aesthetic qualities, versatility, structural stability, and availability.
Environmental & Structural Benefits of Using Wood Cladding as an Exterior Building Material
According to the Environmental and Energy Study Institute, residential and commercial buildings are responsible for almost 40 % of U.S. carbon dioxide emissions1. Fortunately, utilizing exterior wood cladding helps to offset the emissions.
Wood is a carbon sink: Trees absorb carbon from the environment and hold onto the carbon through their life cycle – from a tree to building material. They use the energy from carbon dioxide in the air, sunlight, and water from the roots to create nutrients that fuel the rest of the tree. This means that solid wood building materials have a net-negative C02 profile, which helps reduce carbon emissions.

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

Benefits of Wood Based Designs in Interior Applications
Americans spend a whopping 93 percent of their lives indoors breathing in recycled air. What most don’t realize is the air we breathe indoors is on average 2X to 5X more toxic than what we breathe outdoors due to insufficient ventilation, synthetic building materials, and volatile organic compounds (VOC) from a variety of products and materials. Thus, for many people, the health risks related to indoor air pollution may be greater than that of outdoor exposure.
Incorporating natural materials such as real wood flooring into a built environment helps to reduce blood pressure, heart rates, and stress levels, whilst improving well-being, creativity, cognitive abilities, and the air we breathe. Wood flooring is a timeless option, as it has been a favored building material for years. With multiple species, finish options, color variations, widths, and grade options, it can easily match any design aesthetic. When properly installed and maintained, wood floors can outlast many other flooring materials. reSAWN offers solid and engineered construction wood flooring that not only looks great but is sustainable as well.
Long-Lastingand Durable: Whether solid or engineered construction, wood flooring is durable and can withstand the wear and tear of everyday life. This durability means a longer lifecycle for the product, especially when refinishing is considered instead of replacing. A recent report from Bona found a 78% carbon footprint reduction when refinishing rather than replacing wood floors2.
Better Air Quality: The EPA found that wood flooring improves overall air quality3. Wood flooring minimizes the acclimation of dust, dander, and other pollutants due to its solid surface. Choosing a finish that has a low to zero VOC content is also attributed to the air quality. reSAWN’s Hardwax-Oil finish is non-pollutant and completely non-toxic. It does not contain biocides, preservatives, or lead-benzene and is 100% VOC-free.
Biophilic Design: Numerous studies have found incorporating aspects of nature into the built environment, such as real wood flooring, can help the mental health and wellbeing of the building’s occupants.

Certifications for Green Building Initiatives
There are many certification programs that are often used by architects, designers, homeowners, and builders as guidelines and a solid framework for sustainable building initiatives. Although different programs have varying levels of standards, they all focus on building a healthier, more sustainable future in both the commercial and residential building sectors. At reSAWN TIMBER co. we focus on LEED®, Forest Stewardship Council (FSC®), and The Living Building Challenge.
LEED
LEED, also known as Leadership in Energy and Environmental Design, is the most widely used green building certification system in the world. LEED-certified buildings save money, improve efficiency, lower carbon emissions, and create healthier places for people. Most projects, whether it’s new construction, a renovation, or an interior fit-out can apply for LEED credits.
A project earns LEED points/credits by following guidelines relating to carbon, energy, water, waste, transportation, materials, health, and indoor environmental quality. Points can be earned for each recognized green building feature. The more points obtained, the higher level of certification a project can achieve. The different levels of certification include LEED Certified, LEED Silver, LEED Gold, or LEED Platinum. A 2014 UC Berkeley study4 found that by building to LEED standards, buildings contributed 50% fewer greenhouse gasses than conventionally constructed buildings due to water consumption, 48% fewer greenhouse gasses due to solid waste, and 5% fewer greenhouse gases due to transportation.

15% of credits impact water resources
10% of credits affect biodiversity
10% of credits related to the green economy
5% of credits impact the community
5% of credits impact natural resources
A factor of LEED certification is material selection. Material selection can affect many aspects of a project, including comfort, air quality, and human health. reSAWN TIMBER co. lists earnable credits on all our products, so you can know firsthand what credits your project qualifies for. Some of the common credits reSAWN products qualify for include certified wood, rapidly renewable materials, and low-emitting materials.
FSC®
FSC®, also known as the Forest Stewardship Council, focuses on responsibly managed forests as a way to extend trees’ natural carbon sequestration throughout their lifecycle. FSC’s mission is to promote environmentally appropriate, socially beneficial, and economically viable management of the world’s forests. Two types of certification are offered, Chain of Custody and Forest Management. The certifications provide an honest, transparent look into the path the products take from the forest to a finished FSC® certified product.

FSC® chain of custody certification assures that products sold with an FSC® claim originate from well-managed forests, controlled sources, or reclaimed materials. It includes the multiple stages of the product, including sourcing, processing, trading, and distribution. Certificate holders are also required to implement the FSC® core labor requirements in their operations, ensuring the organization does not partake in forced labor or discrimination in employment. reSAWN holds a Chain of Custody certificate, allowing most reSAWN products to be certified in 1 of 3 categories: FSC® 100%, FSC® Mix, and FSC® Recycled.
Living Building Challenge
The International Living Future Institute is leading the transformation toward a civilization that is socially just, culturally rich, and ecologically restorative. They understand that humanity needs to reconcile its relationship with the natural world and leave it better than it was found. ILFI offers many certifications and challenges to better the built environment, including the Living Building Challenge, Living Product Challenge, Living Community Challenge, and Zero Energy and Zero Carbon certification.
The Living Building Challenge is a philosophy, advocacy tool, and certification program for sustainable buildings. The challenge’s goals focus on resource conservation and sustainable practices in the architecture, design, and construction of all buildings while connecting the communities and their inhabitants to the world surrounding them. These goals can apply to new construction, existing buildings, landscape or infrastructure, and internal projects in the residential and commercial sectors. The program is constantly evolving – the current standard is The Living Building Challenge 4.0. They use a flower with seven petals, or Imperatives, of actionable standards to build and design for a Living Future.
Place: The Place petal focuses on understanding and honoring the place where the built environment stands while honoring, protecting, and enhancing the ecology surrounding the project.
Water: The Water petal focuses on an inherent understanding of the value of water – minimizing waste, avoiding pollution, using less, and not using potable water for irrigation to ensure responsible water use.
Energy: The Energy petal focuses on renewable energy that helps the building operate in an energy-efficient and pollution-free manner, minimizing carbon emissions related to energy.
Health & Happiness: The Health & Happiness petal focuses on creating healthy spaces that allow natural light, healthy air, and a healthy interior environment that benefits the project’s occupants and the nature surrounding it.
Materials: The Materials petal focuses on building materials that are non-toxic and ecologically restorative while being transparent about their ingredients. 50% of wood products must be FSC®, salvaged, or harvested on-site either for the purpose of clearing the area for construction or to restore or maintain the continued ecological function of the site. The remainder must be from low-risk sources5. The project must also contain one Declare label product per approximately 2,153 square feet of gross building area.
Equity: The Equity petal focuses on creating and nurturing communities that are just and inclusive, enabling all people to prosper and reach their full potential. This includes making the building accessible to all while ensuring that the building is mutually beneficial for its inhabitants and the community it supports.
Beauty: The Beauty petal focuses on connecting to nature through biophilic design. A beautiful building starts with people and nature and their symbiotic relationships to place, climate, culture, and community.
As of April 2019, ILFI reported 563 registered Living Building projects in 29 countries. Abodo Vulcan Cladding received the Declare label from the International Living Future Institute, affirming their products are Red List Free, making it an excellent building material choice. reSAWN TIMBER co. is proud to be the exclusive manufacturer and distributor of Abodo thermally modified Vulcan cladding, slats, and decking products in the USA.
