Wraptite External Air Barrier
Wraptite combines important properties of vapour permeability and airtightness in one affordable self-adhering membrane. Wraptite has received BBA certification (no. 15/5274) for use in both roofs and in walls behind the rain screen cladding making it an ideal choice for commercial projects with large uninterrupted facades. It is the only self-adhering vapour permeable air barrier certified by the BBA.
It fully bonds to virtually any substrate, with a key benefit being its ease of installation, negating requirement for sealants or tapes.
Wraptite airtight membrane makes a significant contribution to a building’s thermal performance by preventing lateral air movement, but it also contributes to a healthy living environment and a healthy building, thanks to its vapour permeability. With a rating of Sd 0.039, it provides a high degree of vapour permeability in a commercial quality, self-adhered, airtight breathable membrane.
Specifiers can have confidence that Wraptite’s performance is unsurpassed.
