This flexible membrane can also be used as an airtight seal for all kinds of wall connections. For indoor use only.Instructions for useSWS Inside Extra may only be used on the inside. Depending on the situation, the installation of SWS Inside Extra can be carried out before or after the installation of the facade element (e.g. window frame). There are 2 methods for applying SWS Inside Extra. You can work with a strip from one piece or you can work with 4 separate strips. In both cases, extra material must be provided for the corners (approx. 5 to 10 cm per corner). After unrolling and removing the protective film, glue the film with the exposed adhesive strip (on the printed side) to the side of the facade element, or remove the protective film from the adhesive strip on the unprinted side and glue the film to the front of the facade element. Always ensure that the text is readable and facing the visible side. Remove the remaining protective film evenly. Glue the film, not too tightly, to the rough construction to absorb any movements between the different building elements, but avoid folds. The adhesive layer of the film is pressure-sensitive; the more firmly it is pressed, the better the adhesion. Use a pressure roller for this.
