Thermory USA Hardwood Decking
Thermory wood decking is a thermally modified hardwood product made from sustainably harvested American ash. Thermal modification gives the decking the same resistance to rot and decay as tropical woods, without harming the environment. Thermory is a maintenance-free product, aging naturally to a silver-grey color if left untreated, or maintaining a chocolate brown luster if oiled yearly with standard deck oil. It is available in 1x4 and 1x6 in both 4/4 and 5/4 thicknesses.
