Waterproof Breathable Membrane for European Market

Product Descrition & Application

Xiyun Waterproof Breathable Membrane is 3-layer thermo-bonded: PP non woven fabric of top and bottom layer, Micro-porous PE film, between the two layers. is to form waterproof and breathable membrane, with excellent performance at water resistance(>1500/3000mm H2O) meanwhile with particular function of high vapor permeability(1800g/3000g/m2/24h), which mainly used in construction as underlay on pitched roofs or walls.

Breathable roofing underlay positioned immediately above the insulation layer in a warm pitched roof, or in a cold pitched roof (ventilated or unventilated). Breathable roofing underlay for use under tiles and sheeted roofs, over open rafters or on to fully boarded substrates. Breather membrane for timber frame wall construction.
