Belgafix plus is a vapour control layer and air tightness membrane, which can be used in conjunction with the most common insulation products for pitched roofs. The membrane is vapour-inhibiting with a static sd-value of 5m.
Due to the fleece reinforcement at the backside of the membrane, Belgafix plus has a better tear resistance in comparison to standard non wooven membranes.
