Wraptite - Barn Conversion

Wraptite-SA, the only self-adhering vapour permeable air barrier certified by the BBA, was installed as part of the construction of the roof, with the combination of Wraptite and Wraptite Tape applied to the walls. The use of the Wraptite system will significantly enhance the building’s thermal performance by preventing lateral air movement. It also provides high vapour permeability in a continuously sealed, airtight membrane.

Wraptite Tape was selected because it is not only an effective airtight barrier, but because its high vapour permeability allows damp sheathing to dry quickly, and moisture vapour to escape. Thus ensuring good indoor air quality and reducing the likelihood of mould, mildew, condensation, timber distortion and metal corrosion. The rainscreen cladding, insulation and Wraptite Tape was installed by contractors Midas Cladding as the second school in the refurbishment programme for Durham Direct Services, with more schools to follow bringing the buildings in the county to a higher standard of performance.
