Dasso 2ply bamboo flooring is made from two layers of bamboo,with a 4mm top layer and across 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 top layer 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.
