Wraptite-SA the high performance airtight membrane from the A. Proctor Group has once again surpassed the initial air test targets for an innovative new children’s home project. A new children’s home in Havant is one of a series of buildings currently being built for Hampshire County Council to Passivhaus standard, which will help to achieve a significant reduction in energy bills for each property.
In order to successfully achieve the Passivhaus standard, buildings are required to pass three air tests throughout the construction process. The development at the new children’s home was designed requiring an airtightness level of less than 0.5. Wraptite-SA was applied externally to the timber frame panels in continuous pieces by chartered building company Raymond Brown Building creating a highly insulated and sealed finished building, and achieving the required standard. Initial air test results of 0.38 were achieved coming well below the 0.5 air permeability target. All the more impressive, since this was recorded even before the installation of the internal VCL Procheck 500, also provided by the A. Proctor Group.
The use of Wraptite-SA, the only self-adhering vapour permeable air barrier certified by the BBA, makes a significant contribution to a building’s thermal performance by preventing lateral air movement. It also provides high vapour permeability, which allows any water vapour to escape the wall construction efficiently thereby avoiding any interstitial condensation problems.
Traditional use of internal air barriers can also be more complex and costly to install, due to the need to accommodate building services such as electrical, lighting, heating and drainage systems.
