Thermory® Products Available
Through Mason’s Mill & Lumber

Whether you’re designing a modern commercial façade, building a backyard retreat, or crafting a warm interior space, Thermory® offers options for every vision:

Decking: Rich tones and superior stability for outdoor living spaces.

Cladding & Siding: Eye-catching textures and profiles for long-lasting curb appeal.

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.
