Why Beyond Lumber Thermally Modified Woods
Thermally modified wood isn’t just beautiful, it’s engineered through heat and steam to perform in demanding outdoor environments. By altering the wood at a cellular level without chemicals, it becomes highly resistant to moisture, decay, and pests while minimizing warping and shrinking. With a smooth, splinter-resistant surface, thermally modified Ash delivers long-lasting performance, low maintenance, and a clean, modern aesthetic. Whether you’re building in Malibu, the Bay Area, or anywhere along the coast, it’s built to stand up to the elements.
