Hard Pine

A different kind of pine.

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.

01

Stable

Thermal modification reduces moisture uptake and seasonal movement.

02

Distinctive

Hard Pine delivers stronger visual grain than many competing softwoods.

03

Value

Designed to deliver premium thermowood performance without premium imported-product pricing.

*Janka values shown are reference values for untreated base species (lbf), not post-modification product test results. Thermal modification can alter mechanical properties. Exact performance varies by species, grade and treatment schedule.

Comparison is intended as general material guidance, not an engineering specification. Product-specific laboratory testing should govern structural, code, fire, durability or warranty claims.

The process

Real wood, transformed by heat.

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.

01

Select

Quality Hard Pine selected for appearance and grain.

02

Modify

A controlled thermal cycle changes the wood through its cross-section.

03

Mill

Material is precision milled into siding and architectural profiles.

04

Finish

Use naturally weathering wood or specify an appropriate coating system.

Finish Color Range

Architectural tones for every project.

Color names are representative industry descriptions. Final appearance varies by wood species, grain, preparation, coating system, and weather exposure.

Fire-Retardant Treatment Available

Options for Colorado wildfire-resilient construction.

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.
