Select Cut® ThermalGuard by PureWood® begins as natural, renewable lumber. Using state-of-the-art thermal modification technology, each ThermalGuard board is dried to reduce moisture content. This process has been proven to preserve the material for up to twenty-five years without the need for chemical additives. Our unique engineered profile accommodates a hidden fastener system that is simple to use and easy to install. ThermalGuard is further enhanced with a factory-applied, premium sealant specifically designed for ThermalGuard. This rich looking, real wood product offers remarkable resiliency to rot, decay, and other elements. ThermalGuard by Purewood® is an impressive alternative to cedar and more cost effective than most composite decking products. It is the ideal choice for your next decking project.
ThermalGuard has a 100% acrylic, factory-applied sealant (PWS by
PureWood®) specifically made for ThermalGuard. In order to
protect ThermalGuard from the natural weathering process or silvering
of product due to sunlight, a dark acrylic sealant should be used
prior to or immediately following installation. Visit

FAQs
Q: Is ThermalGuard by PureWood® a composite?
A: No, composites are made from wood flour and plastics mixed together. ThermalGuard is 100% natural wood fiber that comes from renewable mature trees.
Q: What is the TMW process?
A: TMW means Thermally Modified Wood. The TMW process provides the correct combination of temperature, time, and conditioning to modify the wood to protect itself, due to physical, chemical, and biological changes. Most wood sugars are removed during the TMW process, leaving a product that is highly resistant to rot and decay. At the same time, the TMW process evenly distributes wood's other naturally occurring protective agents throughout the boards, providing additional protection from attack of outdoor elements.
Q: How is ThermalGuard any different than treated wood products?
A: Treated wood is injected with chemicals for longer life. No chemicals are added to ThermalGuard.
Q: What makes this wood "pure"?
A: The Thermally Modified Wood (TMW) process contains no additives. The process of using high heat and steam, which thermally modifies the wood, only removes the parts that encourage rot and decay. No pesticides, no plastics, no chemicals or metals are added as part of the process. After the TMW process is complete, ThermalGuard is processed and protected with a factory-applied, premium sealant, specifically made for thermally modified wood. Once applied, the sealant is safe and non-toxic, helping to further enhance ThermalGuard's performance against warping and checking.
Q: What's ThermalGuard's life-expectancy versus normal wood?
A: All wood requires a little TLC, and ThermalGuard is no different. Normal outdoor exposure with minimal cleaning is all that is necessary for our warranty against rot, decay, and excessive checking and warping.
Q: How long has TMW been around?
A: Thermally Modified Wood (TMW) has been in production since the early 90's in Scandinavia and Europe.
Q: Do I have to reseal ThermalGuard?
A: No, it is not necessary to protect the wood from decay. It has been partially protected at the factory with a sealant to help protect against warping and checking. You need to end coat all cut and exposed ends after installation. However, to protect the wood from the natural weathering process or silvering of product due to direct sunlight, you should apply a finish coat of PWS by PureWood prior to or immediately following installation. This will give you the best results and performance.
Q: Can I use another brand of sealant with ThermalGuard?
A: PWS by Purewood® is recommended by the manufacturer, however, any acrylic-base stain can be used.
Q: If I don't reapply the sealant, will ThermalGuard's color change over time?
A: Yes, just as with raw wood, it will age by turning gray or silver in color. ThermalGuard will lose its brown color and UV protection over time due to wear and UV radiation from the sun if PWS is not applied.
Q: How often do I have to seal ThermalGuard in order to maintain the rich color?
A: Frequency is based on specific weather conditions and exposure to sunlight. Manufacturer's recommends PWS be reapplied every 2-3 years. Deck preparation is easy, simply brush the surfaces with detergent & water, rinse, and reapply PWS. Remember, thin coats are better than thick coats.
Q: What distance between deck joists can PureWood handle when building a deck?
A: ThermalGuard deck boards are a full 1-1/4" thick, and can span 16" on center, 12" on center for stairs, stick with the conventional 16" on center for the best and most solid floor. Deck boards are actually an integral part of the structural system; increasing the integrity of a deck with a few additional joists is worth the end result. Due to ThermalGuard's high dimensional stability and low shrink rate, a 3/16" -1/4" gap between boards is recommended.
Q: Do I have to use the hidden fastener system?
A: No, ThermalGuard can be fastened just like normal decking. We do, however, suggest pre-drilling when near the end or edge of each board. ThermalGuard is also available in a non-grooved profile. Face screwing within the body of the deck board is best when using a self-drilling screw (#9 x 2-1/2") with head being flush with surface.
Q: The grooved board is great, but I need a solid board for stairs and trim?
A: ThermalGuard is available in a flat board for top-rail, stairs, and trim boards.
