Thermory Thermo-Treated Wood (Alternative to Ipe) - Now In-Stock at Kuiken Brothers Building Materials in NJ & NY

Thermory Wood is a solid, hardwood decking board produced from Northern American White Ash, which has twice the strength of cedar, is harder than red oak and half the weight of Ipe. Each board undergoes a Thermal Modification Process that rearranges the wood’s cell structure to reduce movement related to moisture and removes wood sugars for increased durability against rot and insects.
