Bamboo X-treme





The fast growth and abundant availability makes bamboo a perfect source for many applications in and around buildings. With good reason, it’s often called ‘the building material of the future’. However, bamboo as a raw material cannot be used outdoors without a protective treatment. Due to its high “sugar”-components, bamboo is more susceptible to being attacked by micro-organisms and fungi. Let us explain how we get from the raw bamboo material to the final product, MOSO® Bamboo X-treme®, through a production process called Thermo-Density®.

MOSO® Bamboo X-treme® Outdoor Decking

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 possible in the appropriate European standard (see technical characteristics below) and increases the hardness and stability. 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.

The new generation in decking

MOSO® Bamboo X-treme® Decking boards are made from compressed, thermally treated bamboo strips. Bamboo X-treme® is suitable for outdoor applications, especially as decking. The extreme stability of the material ensures a very durable bamboo surface or outdoor living area, with the natural appearance of hardwood.

​Bamboo for use in Wildland Urban Interface zones

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 fire resistant without the use of ecologically unfriendly and expensive fire retardants.

WUI approved bamboo decking and siding

The Bamboo X-treme® Decking boards are rated compliant in accordance with Chapter 7A California Building Code. The bamboo decking system is tested following US standard ASTM E84, reaching Class A Flame Spread. 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 like rooftops and porches. With over 25 million square foot decking installed since 2008, the year of introduction, MOSO® Bamboo X-treme® Decking proved to be a durable, sustainable and certified solution. Together with architects, installers and distributors in California, MOSO North America introduces the WUI approved decking and siding as a next step in the introduction of the next generation in sustainable outdoor products.

Exterior Bamboo Products with the highest durability class

A unique heat treatment process, called Thermo-Density®, provides Bamboo X-treme® the highest durability class possible within the appropriate EU norms*. The Thermo-Density® process modifies and removes sugar molecules which are naturally present in untreated bamboo. With this treatment bamboo is no longer a food source for fungi and micro-organisms. Furthermore, the process increases the density – making the bamboo planks very hard.
