1. Introduction of Breathable waterproof membrane / underlayment / house wrap
House wrap is also known as roofing underlayment or housewrap,
which is a polymeric composite waterproofing material. It is produced with PP non-woven
fabric + PE fuctional film + PP non-woven fabric. The PP fabric works as protection and
reinforcement, while the micro-porous PE film is the functional layer which is water-resistant
but allow water vapour to pass through.
House wrap is widely used in roofing or wall system, outside the insulation
layer. It is water resistant, which prevents the outside water get inside, while allows the inside
vapor or humidity/moisture permeates to the exterior. This can keeps the insulation system dry
and prevent damages to the roof/wall system or inside facilities from condensed water dew. By
using breathable waterproof membrane, the insulation system can be perfectly protected and
sustainable energy saving achieved.
