THERMALLY MODIFIED DECKING & SIDING
As the name states, this is wood. All natural wood. Nothing added, just dried differently. Thermally modified wood is a superior exterior lumber used for decking and siding primarily. But instead of using tropical hardwoods or naturally rot resistant species, the thermal modification process allows us to use much more commonly available (and affordable) FSC certified hardwood and softwood species like Ash, Oak, Iroko, or Pine.
Drying Ash, Oak, Iroko, or Pine to significantly higher temperatures in a controlled environment does however modify the cell structure to produce a wood that is dimensionally stable and resistant to bugs and rot. The wood maintains nearly the same working properties after drying and presents a darker, baked golden brown hue. It is still the same species of wood, just without the seasonal movement headaches and with all the sugars and water baked out so the bugs leave it alone and water beads up and runs off. In other words, its the same wood, just better.
