SWS inside extra - Air and vapor-tight membrane - Soudal

SWS Inside Extra is a membrane for sealing window connections against air and water vapor.

• It is intended for indoor use. SWS Inside Extra features a powerful adhesive strip on one side for excellent adhesion to the window frame, and, on the other side, an adhesive layer across its entire surface.
• It can be glued directly.
• It is part of the SOUDAL WINDOW SYSTEM (SWS).

Features :

• Airtight
• Waterproof
• Adhesive layer across the entire surface for adhesion to the structure (pressure sensitive)
• Adhesive strip for installation on a window profile (pressure sensitive)
• Flexible
• Product suitable for ceiling mounting or gluing
• Protective film
• Easy installation, folds easily into corners
• Tear-resistant
• Good temperature resistance.

Applications:

• SWS Inside Extra window membranes ensure an airtight and vapor-tight connection between the window frame and the surrounding load-bearing structure.
• This flexible membrane can also be used as an airtight seal for all kinds of wall connections.
• For indoor use only.

Instructions for use:

1. SWS Inside Extra can only be applied indoors. Depending on the situation, SWS Inside Extra can be installed before or after the facade element (e.g., window frame).
2. SWS Inside Extra can be applied using 2 methods.
   It is possible to work with a single strip or with 4 separate strips.
   In both cases, extra material should be allowed for the corners (approx. 5 to 10 cm per corner).
3. After unrolling the membrane and partially removing the backing, apply the adhesive side (printed side) to the facade element or remove the backing from the adhesive strip on the unprinted side and apply the film to the front of the facade.
4. Always ensure that the text is oriented so that it is readable on the visible side.
5. Remove the remaining protective film evenly.
6. Stick the film, not too taut, onto the main structure, in order to compensate for any movements between the different construction elements but avoid folding it.
7. The film's adhesive layer is pressure-sensitive: the harder you press, the stronger the adhesion.
8. To do this, use a rolling roller.

FAQ - Frequently Asked Questions

1. What is the purpose of an airtight and vapor-tight membrane?
   It prevents air and water vapor from passing through the walls, thus protecting the insulation and structure from moisture, while improving the building's energy performance.
2. What is the difference between SWS Inside and SWS Outside?
   SWS Inside is an airtight and vapor-tight membrane (for interior installation). SWS Outside is a watertight but vapor-permeable membrane (for exterior installation). The two are complementary and form a complete sealing system.
3. Can SWS Inside Extra be used in renovation projects?
   Yes, it is perfectly suited to renovation projects, particularly for improving the airtightness of existing buildings and reducing energy losses.
4. Is the membrane compatible with all types of insulation?
   Yes, the SWS Inside Extra is compatible with most common insulation materials (mineral wool, wood wool, synthetic insulation, etc.).
5. Is it mandatory for a low-energy house?
   It is not always mandatory, but highly recommended to achieve the required airtightness performance (blower door tests).
6. Should Soudal accessories be used?
   For optimal and long-lasting sealing, it is strongly recommended to use compatible SWS adhesives, glues and sealants.
