CLADDING & SHEETING Airtightness for contemporary cliff top house An impressive new contemporary cliff top house in Poole, Dorset, has benefitted from the superior airtightness performance qualities of Wraptite-SA from the A. Proctor Group. RB Studio Architects designed the property at 33 Cliff Drive in a modern open-plan living style over three floors. Local developer Portus Homes selected Wraptite-SA, which combines the important properties of vapour permeability and airtightness in one self-adhering membrane. Wraptite-SA, the only self-adhering vapour permeable air barrier certified by the BBA, was applied directly to the concrete walls behind the Grespania Coverlam porcelain external cladding. The introduction of Wraptite-SA in the construction made a significant contribution to the building’s thermal performance by preventing lateral air movement. 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 an airtight, vapour permeable membrane that could be RB Studio Architects designed the property used directly onto the blockwork walls. Wraptite-SA was the perfect choice in that it is self-adhesive, 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. www.proctorgroup.com/air-barriers Prater begins work on two new contracts Prater has begun work on two major projects in the Midlands and the North West.
