Thermally Modified Wood Products

Landmark Lumber is the regional distributor of ThermaPro Wood thermally modified wood products in the Mid-Atlantic region. Thermal modification uses a heat/steam process to remove organic compounds from the wood cells so they can not hold water, expand, contract, or provide nourishment for insects or fungi. This produces a naturally durable wood that is resistant to water, insects, and decay without the use of chemicals. Thermally modified wood, while new to the U.S., has been the exterior wood standard in Europe since 1990 due to its longevity, sustainability and chemical-free properties.


Prefinished Cladding

ThermaPro Wood Prefinished Thermally Modified Nickel Gap Wood Cladding can be hung vertically or horizontally as exterior siding, soffit or rainscreen and makes a stunning indoor/outdoor ceiling or accent wall. ThermaPro Cladding is a fully sustainable, eco-friendly, long-lasting natural wood building material. 


Thermally modified pine is profiled to 1”x6” Nickel Gap Tongue & Groove and factory finished on all sides with CUTEK ® Extreme high performance wood oil preservative. Available in lengths from 8 to 16 feet, ThermaPro prefinished cladding arrives ready to install. Plus we offer a full line of matching trim and fascia boards. Customizations include dutch lap, shiplap, T&G and V-groove profiles, and six custom colors with UV protectant for color maintenance.


Prefinished Rainscreen & Slatting

ThermaPro Wood Rainscreen & Slatting can be used for vertical rain screens, privacy walls, shade screens, fences, and artistic detail providing shade, privacy, architectural dimension, and the warmth of real wood for any façade. Thermal modification extends the life and stability of real wood without chemicals, making it naturally resistant to rot, warping and insects making it the perfect wood slatting material.



Improved weather resistance and dimensional stability make thermally modified Southern yellow pine the ideal natural wood decking material. Thermally modified wood provides superior rot and insect resistance, along with a rich color that can be maintained with UV protectant or left to silver to achieve that beachy look, all without cupping or cracking.


ThermaPro Decking products are prefinished with CUTEK ®  Extreme in clear, which slows the silvering process. CUTEK ® color tones with UV protectant are also available. 

ThermaPro’s full line of decking, railing and deck tile products make it easy to create beautiful, long-lasting decks, swimming pool surrounds, terraces, balconies and piers. It's chemical-free sustainable wood that will last decades.
