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.
Permo forte vapour permeable underlay has also been 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 considerably below the 0.6 MN/sg requirement for walls.
