Soft to the Touch. Strong Where it Counts.
Real wood, cooked at over 400 degrees in an oxygen-starved kiln. The sugars that feed rot are baked out, moisture movement drops by half or more, and the board that comes out is stable enough for siding, ceilings, and saunas — with nothing added but heat and steam.
Ayous, Scandinavian, and Ash.
Same thermal process, three different personalities. All three ship kiln-modified, end-matched where profiled, and ready for custom milling.
Thermally Modified Ayous
African hardwood, nearly knot-free, feather-light. The architect's pick for ceilings, soffits, and long clean siding runs where straight grain has to read from the street.
Scandinavian Thermally Modified Wood
Scandinavian material with visible grain and honest character. A versatile entry into thermally modified cladding — architectural when planed and warm in overhead applications.
Thermally Modified Ash
Dense American ash, chocolate-deep after modification. Hard enough for decking and stair treads, handsome enough for saunas and feature walls.
Thermally modified wood vs. the alternatives.
| Thermally Modified | Autoclave Treated | Kiln-Dried | Other Untreated | |
|---|---|---|---|---|
| Treatment method | Heat + steam only | Pressure chemicals | Heat drying | None |
| Chemical-free | Yes | No | Yes | Yes |
| Moisture absorption | Very low | Moderate | Moderate | High |
| Dimensional stability | Ultra stable | Fair | Good | Poor |
| Rot & decay resistance | Class 1–2 | Class 2–3 | Species dependent | Low |
| Color consistency | Through the board | Surface tint | Natural variation | Natural variation |
| Warranty | Up to 20 yr | 10–15 yr | Varies | None |
Real wood, without wood's bad habits.
Stability first
Thermal modification cuts moisture movement by half or more. Long siding runs stay straight through wet seasons.
Rot resistance, no chemicals
Heat and steam only. The sugars fungi feed on are cooked out — durability class 1–2 without a drop of preservative.
Color through the board
The brown goes all the way through. Cut ends, rips, and profiles match the face.
Light on the wall
Modified boards weigh noticeably less than unmodified stock — faster installs on ceilings and soffits.
20-year warranty
Two decades of coverage on exterior applications, backed by our own import chain.
Custom milling
Shiplap, nickel gap, T&G, rainscreen — any profile in any of the three species, milled to order.
Facades first, then everywhere else.
