Foil DuoSL600

The blaugelb Foil DuoSL600 is a special plastic foil with self-regulating properties for the sealing of connecting joints of windows and doors. It has a fleece backing and is fully self-adhesive. The integrated plastic foil can vary its sd-value, enabling it to regulate the water vapour permeability of the joint when used on both sides (inside and outside) so that it retains the capacity to dry out the whole year round.

The blaugelb Foil DuoSL600 is watertight against driving rain up to at least 600 Pa and UV-resistant for at least 4 months. It is elastic and absorbs the movements of the components. On the fully adhesive side, the slit protective  paper allows easy attachment to the substrate without the need for additional foil adhesive. The self-adhesive strip on the fleece side means that the blaugelb Foil DuoSL600 can also be bonded on both sides. The self-adhesive strip on the fleece side is covered by protective paper. Because the blaugelb Foil DuoSL600 can be used on the inside and outside, there is no danger of confusion and no need for expensive storage.

The blaugelb Foil DuoSL600 is secured to the window profile with the narrow self-adhesive strip and bonded with the masonry on the fully adhesive side. The self-adhesive property makes it suitable for bonding to commercially available window profiles and the standard construction substrates. The bonding can be corrected in the first few minutes. The blaugelb Foil DuoSL600 can be plastered, bonded and painted over on the fleece-backed side and can thus be installed completely hidden.
