Frances Strachan-Friar commented on how the selection of Wraptite has benefitted the development. “The specification of the correct type of airtightness barrier was critical in achieving thermal efficiency. Wraptite was chosen because it allows the airtightness layer to be fitted to the outside of the construction. In doing so, the external application of Wraptite provides essential protection in the form of waterproofing and weatherproofing for the CLT during the build.

“The Wraptite system was great and easy to apply, especially around junctions, enabling us to seal all of the junctions completely. The use of a traditional membrane would not have given the same performance. I have previously specified products from the A. Proctor Group, but this was the first time using Wraptite. Proctors provided a comprehensive Toolbox Talk and have been a great support throughout the project.”

The Wraptite system is the only self-adhering vapour permeable air barrier certified by the BBA. It combines the critical properties of vapour permeability and airtightness in one self-adhering membrane. As a result, it provides high vapour permeability in a continuously sealed, airtight membrane.

The high vapour permeability of the Wraptite air barrier allows the substrate beneath to dry quickly and moisture vapour to escape and reduces the likelihood of mould, mildew, condensation, timber distortion and metal corrosion. The vapour permeability of Wraptite also allows any water vapour to escape efficiently, thereby avoiding interstitial condensation problems.

Designed to replace traditional airtightness methods cost-effectively, Wraptite is a low-resistance vapour permeable air barrier, durable, flexible and lightweight, allowing for easy installation, with the added benefit of providing temporary protection against the elements during construction
