ThermalBoard Sustainable Radiant Floor Heating

A Truly Sustainable Radiant Floor Substrate

ThermalBoard utilizes a dense fiberboard made from the agricultural post-harvest waste of rice straw rather than felling trees, large or small. Instead of burning rice straw or letting it rot in water generating methane, the straw is now included in a great radiant heating product.
