Klober membranes in Grand Designs project

Story

Klober air-open underlay tops performance ratings

Klober membranes have been used in a couple’s zero carbon eco-home which featured in the latest series of Grand Designs. The five-bedroom, 4,300sq ft timber frame building on the West Pennine moor has Wallint 50 on the warm side of the insulation to provide an air barrier and vapour control layer. By contrast, Permo forte was installed on the cold side of the insulation to enable moisture within the building to escape and provide a weatherproof barrier behind the timber cladding. Its vapour resistance value of 0.15 MN/sg is well below the 0.6 MN/sg requirement for walls.
