One component, low-pressure polyurethane adhesive for instaling polystyrene boards for thermal insulation by the light-wet method KNAUFMANN is a foam adhesive for dry wall and polystyrene isused for fixing polystyrene boards when insulating outer walls of newly erected and thermorenovated buildings.
The installed polystyrene boards may be polished and pinned approx 2 hours after application, then a reinforced mesh layer may be installed. Properties: Knaufmann foam adhesive for dry wall and polystyrene has good adhesion to all known construction materials. The cured adhesive foam is semihard, flexible, resistant to humidity, non-wearing and resistant to temperatures in the range from -100°C to +100°C. The adhesive foam does not lose its properties with years but it is not resistant to UV radiation. The thermal and sound insulation parameters are excellent.
