MOSO Bamboo Supreme is made from two layers of bamboo, with a 4mm toplayer and a cross pressed bamboo backing. The total thickness is 10mm which is relatively thin compared to other wood floors. However, as with any wood species the basic rule is: the thicker, the less stable the wood (shrink/swell). The 10mm thickness and 4mm toplayer is an ideal compromise between durability and stability and therefore offers a perfect solution for heavy circumstances, like installation on floor heating and/or installation in heavy traffic areas.
