Technical specification

WINS external liquid foil for window insulation window is a ready to use, one-component product forming a vapour-permeable coating (area 1), which regulates the migration of moisture from the window gap to the interior of the building, eliminating foam degradation (area 2). It is chemically neutral and adheres to most construction materials. It creates a flexible and vapour-permeable coating. Thanks to its flexibility, it is perfect for sealing frame-to-reveal joints in WINS systems where there is usually little displacement.

The coating in combination with the WINS Flex or WINS Fast insulating foam and WINS external liquid foil creates a water and wind resistant joint between the frame and the reveal, preventing energy losses and the possibility of humidity and mould formation. The joint sealed with WINS liquid foil is resistant to adverse weather conditions including hurricanes up to 160 km/h. Special WINS external liquid foil for sealing windows is reinforced with polymer fibres and provides a very high - 10 years - UV resistance.
