At present, house wrap mainly consists of three layers: PP spunbonded non-woven fabric, PE macromolecule breathable film and PP spunbonded non-woven fabric. The main materials of spunbonded nonwovens are polyester and polypropylene, which have good high temperature resistance, can strengthen tension, hydrostatic pressure and protect the middle layer, and wrap it on the surface of PE polymer permeable film. The main gas permeability function is the middle PE polymer permeable membrane.
