Bamboo X-treme
Decking and Siding


X-treme Products


The fast growth and abundant availability makes bamboo a perfect source for many applications in contemporary buildings and natural landscaping. The extreme stability achieves the maximum durability class for a natural decking. It has the beautiful appearance of hardwood while contributing to restore the environment.

MOSO® Bamboo X-treme® is a solid, Thermo-Density® decking board, made from compressed bamboo strips. A special heat-treatment process at 392°F (200°C) provides MOSO® Bamboo X-treme® the highest durability class, density and hardness. These qualities allow MOSO X-treme products to be fireproof Class A, the top classification suitable for residential and commercial envelope and landscaping.

Applying X-treme natural bamboo products prevents the heat reflection caused by the most common materials  (metals, plastics, and concrete) used traditionally as siding that heat up the atmosphere and surrounding areas rising normal temperatures.

X-treme Bamboo SIDING

Contemporary architectural projects are increasingly being planned with sustainable and natural materials to reach net zero compliance and the natural bamboo siding accomplishes not only that, but also an outstanding natural look that will change colour into a beautiful brown-grey patina, an added value from mother nature; it enhances the appearance of modern innovative structures.



​Bamboo for use in Wildland Urban Interface zones and WUI approved

MOSO® Bamboo X-treme® Decking and Siding boards have been tested and approved for use in Wildland Urban Interface (WUI) zones. The first and only bamboo decking and Siding can therefore be applied in commercial and domestic applications, in all regions in the US. Thanks to the unique Thermo-Density® production process, the material is naturally fire resistant without the use damaging fire retardants. 


The bamboo decking system is tested following US standard ASTM E84, reaching Class A Flame Spread.  Rated compliant in accordance with Chapter 7A California Building Code. Testing according to European norm EN13501-1 resulted in a Bfl-s1 classification, which is the best class after non-combustible materials. Being so resistant to fire makes Bamboo X-treme® Decking a perfect solution for commercial decking applications or domestic installations.

Natural Bamboo Decking

A unique feature of MOSO® Bamboo X-treme® is the end-matched connection: this can only be done with very stable materials and enables connection of an unlimited number of boards in the length.


The special symmetrical shape of the sides offers the possibility to choose between either the standard groove or the smooth surface, and allows for quick installation with MOSO® Fasteners. Bamboo X-treme® will weather over time to a silver patina.
