Bamboo Dark Brown sub frame joists are made of the same material as Bamboo Dark Brown decking boards: Thermo-Density® heat-treated bamboo, made from compressed bamboo strips.
This unique heat-treatment process at 200°C provides Bamboo Dark Brown with the highest durability class possible in the appropriate EU norms and the compression increases the hardness and stability.
Bamboo is a sustainable alternative to tropical hardwoods and composite products, boasting best in class for its environmental credentials, strength, stability, and longevity, whilst achieving a Euroclass B fire rating without the need for external treatment.
We recommend the use of Bamboo Dark Brown sub frame joists, which are specifically produced for use in combination with Bamboo decking, to optimise the longevity and performance of your deck.
