Kangda is equally suitable whether draped unsupported over rafters or laid directly over insulation. It will allow the escape of water vapour from within the roof structure whilst protecting against wind driven rain, snow and dust, which may penetrate the main roof waterproofing, providing a permanent quality breather underlay, which will last the life of the roof construction.

With unique fiber structure, the waterproof breathable membrane can protect the construction structure from being eroded by wind and rain and strengthen the gas tightness and water tightness as well as boast good breathability which expel water vapour out of the construction, thus avoiding mould and condensation.
