Wraptite air barrier helps create learning environments for 4500 Scottish pupils

The specification and installation of A.Proctor Group’s Wraptite external air barrier is helping three secondary school projects in Scotland achieve the Passivhaus standard – Perth High School, East End Community Campus in Dundee, and Monifieth Learning Campus. As a result of the new school buildings, more than 4,500 pupils will benefit from learning in thermally comfortable classrooms with excellent indoor air quality. All three school projects are being delivered by main contractor Robertson Construction Tayside.  

Wraptite is well-suited to Passivhaus projects, and the different construction methods demonstrate its versatility in helping to meet the standard’s high levels of airtightness. Moving the airtight line to the exterior face of the wall structure avoids a lot of complex detailing around services and other penetrations that typically occur at the internal face. As a fully-adhered vapour permeable membrane, Wraptite saves on labour and material costs, without compromising airtightness levels or increasing the condensation risk.  

Perth High School is a concrete frame with mineral wool insulation and a facing brick facade. The other buildings feature a mix of concrete and steel frame with high performance insulation. Facing brickwork is the finish at Monifieth, while the East End Community Campus will comprise of facing brickwork, precast concrete and cladding.
