New homes benefit from variable-permeability vapour control

New homes benefit from variable-permeability vapour control

A series of 10 newly built affordable Council houses in Montrose, Scotland has been fitted with a high-performing variable-permeability vapour control layer from the A. Proctor Group.

Procheck Adapt is designed to protect the building fabric from the potential risks of condensation and act as an effective airtight barrier.

The project, led by Angus Council, comprises of a mix of one, two and three bedroom properties. Jason Noble, Architect with Angus Council commented, “We required a high performing vapour barrier and air tightness layer, that could be installed on site by our contractor and achieve our performance specification. We wanted an effective vapour barrier and airtightness layer that when installed in accordance with the manufacturer’s recommendations and in combination with the timber kit construction would provide an effective airtightness rating of 4 when tested.” 

Contractor, Andrew Shepherd Construction proposed the use of the Procheck Adapt from the A. Proctor Group. The Procheck Adapt membrane has been designed to offer variable permeability adapting to changes in humidity levels and allowing the structure to dry out in the summer, and on sunny days during spring and autumn, while protecting it from moisture overload in the winter. This is possible because the membrane adapts its vapour resistance to the environment i.e., vapour tight in the winter and more vapour open in the summer.

Procheck Adapt has a translucent structure which eases fixing to structural frames and in combination with its integral tape allows for a fast installation time. It is suitable for a variety of commercial and residential applications and provides airtightness to the structure as well as vapour control.
