Breathable membrane / Breathable roofing underlay
Material: PP nonwoven fabric+PE breathable film+PP nonwoven fabric
The roofing membrane is also called breathable membrane. 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.
Product FeatureBreathable roofing underlay:
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
5).Used for roof construction for sloping roof of the wall curtain,
profiled steel sheet, steel (wood) structure, masonry and so on.
