Windproofing membrane is a vapour-permeable protective layer installed on the outside of walls in frame buildings. Its function is to protect the structure and the thermal insulation layer from the ingress of wind, dust and moisture from outside. At the same time, the membrane allows water vapour to escape from the inside of the envelope. This keeps the envelope dry and the insulation does not lose its thermal properties.
W frame houses The windproofing membrane is installed directly on the wall sheathing, under the ventilated façade or external cladding. The tightness of the joints and the accuracy of the installation are crucial - any leakage can lead to cooling and dampness in the structure.
Modern windproofing membranes are characterised by their high UV resistance, flexibility and durability, making them effectively protect the building from heat loss and material degradation for many years.
