The last series of Grand Designs featured a couple and their zero carbon eco-home which used Klober membranes.
On the West Pennine moor, the five-bedroom, 4,300sq ft timber frame building has Wallint 50 on the warm side of the insulation to provide and air barrier and vapour control layer.
With a vapour resistance value of 0.15 MN/sg, Permo forte vapour permeable underlay is well below the 0.6 MN/sg requirement for walls.
Therefore, on the cold side of the insulation, Permo forte vapour permeable underlay was installed in order to provide a weatherproof barrier behind the timber cladding by enabling moisture within the building to escape.
