Matt Gorvin, Director at Portus Homes explained, “I had successfully worked with Roofshield vapour and air permeable pitched roof underlay from the A. Proctor Group on previous projects, and wanted a airtight, vapour permeable membrane, which could be used directly onto the blockwork walls. Wraptite-SA was the perfect choice in that it is selfadhesive, and could be applied directly over the concrete. The project was originally designed with an energy requirement to comply with the Code for Sustainable Homes Level 3, and by using Wraptite-SA we were easily able to surpass this.”

A key benefit of the system is that Wraptite-SA’s high vapour permeability allows the substrate beneath to dry quickly and moisture vapour to escape. This ensures good indoor air quality and reduces the likelihood of mould, mildew, condensation, timber distortion and metal corrosion.
