OverviewOur range of 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.

Thermal & Condensation Calculation
Demonstrating the thermal performance of a building element, or that the specified construction does not carry an interstitial condensation risk, are important steps in the design and approval process. Get project specific calculations with this service.Request Calculation
Facade and High Rise Building Design
When looking at Facade and Envelope design control of air and vapour movement is an important consideration. So looking at where an internal vapour control layer is actually placed in the fabric or whether an external air barrier would be more suited. So we challenge that, and look more closely at internal vapour control layers for high rise development.
Are they still suitable for high rise? Are they actually redundant? Do we need them at all. Are they in fact a liability in that we rely on them too much for air tightness and vapour control?
Potton Passivhaus Showhouse - 0.5 Air Changes Per Hour
The Passivhaus standard must be demonstrated by means of an airtightness test. The air change rate must be less than or equal to 0.60ac/h (air changes per hour), under test conditions, to meet Passivhaus levels. At a recent Self Build Live event on the 4th March 2016, Potton managed to improve on their target of 0.60 ac/h (air changes per hour), to 0.5 ac/h!
