Soft to the Touch. Strong Where it Counts.
Maximo Thermo improves real wood with controlled heat and steam and no added chemicals. Compare Ayous, Ash, Scandinavian, and Clear Radiata for siding, ceilings, decking, trim, and architectural applications.
Ayous, Ash, Scandinavian, and Clear Radiata.
Four distinct species, all modified with heat and steam and supplied in a natural finish. Choose by grain, weight, application, and available profile.
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.
Thermally Modified Scandinavian
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 Clear Radiata
A smooth-grained softwood with minimal knots and a consistent visual field. Clear Radiata is thermally modified for stable cladding, ceilings, decking, trim, and molding.
Thermally modified wood vs. the alternatives.

Real wood, without wood's bad habits.
Stability first
Thermal modification reduces moisture-related movement for greater dimensional stability. Long siding runs resist warping through changing weather conditions.
Rot resistance, no chemicals
Thermal modification uses heat to improve the wood’s resistance to moisture and decay—without added chemical preservatives.
Color through the board
The rich brown tone extends through the wood, maintaining a consistent appearance on cut ends, rips, and profiles.
Light on the wall
Thermal modification reduces the wood’s weight, making boards easier to handle for siding, ceiling, and soffit applications.
20-year warranty
Two decades of coverage on exterior applications, backed by our own import chain.
Custom milling
S4S, nickel gap, V-joint, fluted, trim, and custom profiles can be coordinated around the species and application.
Facades first, then everywhere else.
