Lunawood
Finnish manufacturer of ThermoWood thermally modified timber products for exterior cladding, decking, interior paneling, and sauna construction. Their thermal modification process heats Nordic pine and spruce to temperatures between 190 and 215 degrees Celsius in a steam atmosphere, permanently altering the wood's chemical structure to resist moisture, decay, and dimensional movement. Lunawood products achieve durability class 2 rating without any chemical preservatives, making them safe for both exterior exposure and direct human contact in sauna environments. The thermal modification process darkens the wood to a warm brown tone while reducing its equilibrium moisture content by approximately 40 percent, virtually eliminating the warping and cupping that plague untreated softwood in outdoor applications. Based in Iisalmi, Finland, Lunawood operates one of the world's largest thermal modification facilities, supplying modified timber to construction and design markets across Europe and beyond.

Accoya Wood
Acetylated sustainable timber. The acetylation process permanently modifies wood cells by converting hydroxyl groups to acetyl groups, dramatically reducing the wood's ability to absorb water. This treatment gives softwood durability and dimensional stability exceeding tropical hardwoods, with a 50-year above-ground warranty against decay. Accoya's consistent performance and machinability make it suitable for windows, doors, decking, and cladding in demanding exterior conditions. The process uses sustainably sourced fast-growing wood species, with the acetic acid byproduct derived from natural sources.
Kebony
Modified sustainable wood. The Norwegian technology impregnates sustainably sourced softwood with furfuryl alcohol derived from agricultural waste, then polymerizes it through heating. The treatment produces a dark, hardwood-like material with excellent durability, dimensional stability, and decay resistance without toxic chemicals. Kebony is used in architectural cladding, decking, and marine applications where traditional tropical hardwood would typically be specified. The process extends softwood lifespan to match or exceed tropical hardwoods while maintaining FSC-certified sustainable sourcing.
Thermory
Thermally modified wood products. The Estonian company uses controlled high-temperature treatment to permanently modify wood properties without chemicals or preservatives. Thermal modification reduces wood's moisture absorption, improving dimensional stability and creating natural resistance to decay and insects. The treatment darkens the wood to rich brown tones that remain consistent, and the process is available for ash, pine, spruce, and other species. Thermory products include decking, cladding, sauna materials, and interior paneling with the modified wood fully compostable at end of life.
MOSO Bamboo
Sustainable bamboo products. The Dutch company produces engineered bamboo products including flooring, decking, cladding, panels, and structural beams from Moso bamboo species. Its Bamboo X-treme decking uses a thermal treatment process that achieves hardwood-level durability with a 25-year warranty. MOSO bamboo grows to harvest maturity in 5 years compared to decades for hardwood trees, making it one of the fastest renewable building materials. The company maintains chain-of-custody certification and sources exclusively from managed bamboo forests in Asia.
Plyboo
Bamboo plywood and panels. The company manufactures bamboo plywood, veneer, and flooring products in various grain patterns including flat, edge, and strand-woven configurations. Its RealCore panels combine bamboo surfaces with FSC-certified wood cores for structural applications requiring specific performance characteristics. Plyboo's products are specified by architects for walls, ceilings, cabinetry, and furniture in LEED and sustainable building projects. The company is part of Smith & Fong, which has manufactured bamboo building products since 1989.
Smith & Fong (Durapalm)
Bamboo and palm wood panels. The company pioneered architectural bamboo and palm wood products in the US market, manufacturing sustainable alternatives to tropical hardwoods since 1989. Its Durapalm line uses coconut palm wood salvaged from plantations past their fruit-bearing years into flooring, paneling, and veneer. The distinctive grain pattern of coconut palm creates a unique visual character that is difficult to replicate with other materials. Smith & Fong products carry FSC certification and contribute to LEED credits in green building projects.
