Thermally Modified Ash
Thermally Modified Ash brings together the natural beauty of American hardwood with the stability and durability needed for demanding exterior applications. Its distinctive grain and rich, darker tone make it a striking choice for decking, siding, facades, and other architectural applications.
Sourced from responsibly harvested North American wood, the ash is thermally modified using only heat and steam (no added chemicals) to create a high-performance material designed for greater resistance to moisture, rot, insects, and seasonal movement.
