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 indoors. 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. It can be applied in one continuous strip or in 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, adhere the foil 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 adhere the foil to the front of the facade element. Always ensure that the text is legible and facing the visible side. Remove the remaining protective film evenly. Adhere the foil, not too tightly, to the rough construction to accommodate any movements between the different building elements, but avoid creases. The adhesive layer of the foil is pressure-sensitive; the firmer it is pressed, the better the adhesion. Use a pressure roller for this.
