Breathable membrane is a synthetic roof underlay for use under pitched roof claddings. It reduces drafts and assists in moisture management.
Consists of a micro-porous water resistant film, laminated to two layers of non woven spun-bonded polypropylene.
Breathable water resistant film reduces the risk of condensation when compared with conventional kraft papers.
It is a functional membrane which is laid on the thermal insulation layer. It is applied to the composite outer wall or sloping roof of the wall curtain,profiled steel sheet,steel (wood) structure,masonry and so on. Material: PP fabric+PP breathable film+PP fabric. Features: 1/,Excellent performance at water resistance . 2/,Light and thin,antiskid,with good low temperature flexibility,suitable for construction in different condition. 3/,Improve water-tightness of building,protect the construction from the invasion of wind and rain,protecting the structural materials and equipments inside roof and wall. 4/,High tensile strength and elongation rate,highly flexibility at low temperature. 5/,Used for roof construction for sloping roof of the wall curtain,profiled steel sheet,steel (wood) structure, masonry and so on.
