What is Wraptite Breather Membrane?

Wraptite external air barriers solve the problem of reliably achieving airtightness in buildings, with a robust two component solution comprising Wraptite & Wraptite Tape. This new approach saves on both the labour and material costs associated with meeting the demands of modern energy efficiency requirements in both commercial and residential buildings.

Moving the air barrier to the outside of the building, away from the ‘services zone’ means there are far fewer potential penetrations to the air barrier and that there is no requirement for expensive specialist components such as airtight junction boxes, light switches or downlighter hoods. Wraptite is a unique external airtight solution, which is not only highly vapour permeable, yet airtight – but also self-adhered to ensure a consistent airtight external seal.

Being full self-adhered, there is no need for mechanical fixings, taping of joints or to the structure and, with good detailing, less EPDM required across the envelope.

Class B, s1-d0 when adhered to standard limited-combustibility sheathing board, e.g. calcium silicate (min. density 653kg/m3, min. thickness 11mm +/- 2mm)

When airtightness is improved, external insulation thickness can be reduced while still meeting the energy performance required.

Where a full wall and roof airtight envelope is required, Wraptite can be used in both applications.The self-adhered backing not only ensures an airtight seal but resistance at laps against water penetration, dust, air infiltration and wind resistance making it an excellent choice for this application.
