Applications

Used for general air- and driving rain tightness on the outside of window-to-wall joints.

Instructions

Depending on the installation method of the window, the placement of the airtightness tape on the outside can be done in two ways. If the window frame lies in the same plane as the outer cavity wall, 4 separate strips are used in which the blue self-adhesive strip is applied onto the visible side of the window frame. If the window frame is built into a niche, is NOT in the same plane as the outer cavity wall, there are 2 methods for applying airtightness tapes. You can work with a single strip or you can work with 4 separate strips. In both cases, apply the tape with the blue self-adhesive strip on the side of the window frame so that the printing is legible from the outside. You can also apply the tape on the front of the window frame (and flip the tape over afterwards). Ensure that the surface is dust, moisture and grease-free. The airtightness tape is also provided with a gray butyl strip which, after the window has been installed, ensures the initial bonding onto the masonry during curing of the adhesive. In order to adhere the tape in an air- and vaportight manner (for example on uneven surfaces), a suitable bonding and adhesive mastic is used, eg Soudafoil 360H.
