Explore one highlight from our growing collection of thermally modified wood products for exterior and architectural applications.
Premium grain. Improved stability. Better value.
We start with selected Hard Pine, including vertical-grain material, then thermally modify it to reduce moisture affinity and improve dimensional stability.
The result is a rich, architectural wood with a pronounced grain pattern and the performance characteristics that make thermally modified wood attractive for siding, soffit, trim and other non-structural exterior applications.
Thermal modification reduces moisture uptake and seasonal movement.
Hard Pine delivers stronger visual grain than many competing softwoods.
Designed to deliver premium thermowood performance without premium imported-product pricing.
A practical comparison for architects, builders and homeowners choosing premium exterior wood.
| Characteristic | Thermally Modified Hard Pine | Thermally Modified Hemlock | Clear Western Red Cedar |
|---|---|---|---|
| Dimensional stability | Excellent | Excellent | Good |
| Moisture resistance | Enhanced by thermal modification | Enhanced by thermal modification | Naturally favorable |
| Decay resistance | Enhanced by thermal modification | Enhanced by thermal modification | Naturally durable heartwood |
| Grain character | Bold / vertical-grain option | Fine / understated | Fine / classic |
| Base-species hardness* | Higher | Medium | Lower |
| Value positioning | Premium performance / aggressive value | Premium | Premium |
Comparison is intended as general material guidance, not an engineering specification. Product-specific laboratory testing should govern structural, code, fire, durability or warranty claims.
Thermal modification changes wood's relationship with moisture. Controlled heat treatment reduces hygroscopicity, producing a more dimensionally stable material and improving resistance to biological decay.
Quality Hard Pine selected for appearance and grain.
A controlled thermal cycle changes the wood through its cross-section.
Material is precision milled into siding and architectural profiles.
Use naturally weathering wood or specify an appropriate coating system.
Color names are representative industry descriptions. Final appearance varies by wood species, grain, preparation, coating system, and weather exposure.
A warm, natural alternative for projects where appearance, stability and authentic wood matter.

All Rocky Mountain Thermo-Wood products can be specified with pressure-applied fire-retardant treatment to support projects designed for Colorado Wildfire Resiliency Code and local Wildland-Urban Interface (WUI) requirements.
Final compliance depends on the selected assembly, exterior-use product labeling and test documentation, local code amendments, and approval by the authority having jurisdiction.
Available specifications, profiles, lengths, finishes and lead times should be confirmed with Rocky Mountain Thermo-Wood before ordering.
Request a sample, current pricing or a project quote—and ask about our growing selection of thermally modified wood species. Builder, architect and lumberyard inquiries are always welcome.
