Natural Thermal Enhancement of Hardwood & Softwood
Thermory® elevates the performance of select hardwoods using a precise thermal process relying only on heat and steam, without chemicals, to enhance durability, dimensional stability, and visual richness.
How It Works
Thermory’s controlled, two-stage method begins by reducing the wood’s moisture to nearly zero over an extended, closely monitored heating cycle. Once dehydrated, we elevate the temperature to species-specific thresholds and then carefully cool and mist the boards.
This complete internal transformation, not just surface-level, yields timber that performs with confidence in both interior and exterior architectural applications.
Thermory® is the clear choice for long-lasting, beautiful biophilic driven design.
