Formerly: SIL vapour barrier

'DURAvapourbarrier' is a high performance water vapour barrier material. It is a cost-effective alternative to conventional products like LDPE films etc. 'DURAvapourbarrier' is composed of thousands of tiny air cells trapped in foam and reinforced with high performance polymeric interlay, which helps reduce the overall permeance. It offers four layers of vapour barrier transmission including two layers of special polymeric interlay.
