This SupaPerm SP100 Housewrap Breather Membrane by Powerlon is a high-performance, vapour-permeable membrane. It is a non-woven, spun-bond polyolefin with exceptional water vapour transmission and hydrophobic (water-repellent) characteristics.
You can also rely on this Housewrap breather membrane's air barrier properties designed to improve the airtightness of your building. The air barrier ensures the building envelope is sealed correctly to control ventilation. This helps prevent heat loss in compliance with Building Regulations Part L.
This Powerlon breather membrane is designed for installations within timber frames, composite structural insulated panels (SIP) and wall panel system designs. As a non-woven, spun-bond breather membrane, it is ideal for industrial roof applications, including metal-clad roofs. It can also be used as breather wall protection if needed.
