bamboo x-treme® siding

MOSO® Bamboo X-treme® siding is a solid, Thermo-Density® exterior bamboo board made from compressed bamboo strips. Our unique heat treatment and compression process guarantees that Bamboo X-treme® achieves the highest durability class possible within the appropriate European norms while increasing stability, density, and consequently the hardness.

Bamboo for use in Wildland Urban Interface zones

Contrary to other wood products, Bamboo X-treme® earns fire safety Class A (ASTM E84) and Class B-s1-d0 (European norm 13501-1) without impregnating the material with expensive and eco-damaging fire retardants. MOSO® Bamboo X-treme siding boards have been tested and approved for use in Wildland Urban Interface (WUI) zones. The first and only bamboo siding can therefore be applied in commercial and domestic applications, in all regions in the US.

Easy installation

With its shiplap profile, Bamboo X-treme® siding installs quickly with fasteners and screws. The clips fit neatly in the side grooves of the boards and screwed into the battens. With this method, it is not necessary to pre-drill the siding boards.

Sustainable alternative to hardwood siding

MOSO® Bamboo X-treme boards provide a superior sustainable alternative to tropical hardwoods. Bamboo X-treme requires very low maintenance and withstands temperature changes with little shrinking and swelling. Second only to its durability and ecological advantages is its beautiful, natural appearance. The natural structure of the material rivals the best hardwoods and just like all hardwoods turns grey over time, creating an attractive weathered look.
