Product Features

Soudal Window System (SWS):

'Soudafoam Window & Door SWS' is a product which is part of the Soudal Window System (SWS).

The professional window-joint system SWS is a combination of several products which provide the seal between exterior joinery and the structural envelope.

In new buildings, this is a joint of ±2cm, but SWS can, of course, also be used for renovation of all sorts of exterior joinery: aluminium, wood and PVC. SWS also offers solutions for passive houses and timber framed houses.

SWS has been officially tested in conjunction with various parameters and in various setups. When properly installed, SWS offers:

  • Airtight

  • Lasting Thermal and Acoustic Insulation

  • Weather Resistance


This product is supplied in Gun Grade cans with DuraValve™.

DuraValve™ is a unique valve system that improves the yield and performance of Soudafoam products over much longer time periods than standard valves.

DuraValve™ puts an end to commonly known issues such as poor yield and non-extrusion of PU Foams and is a standard for most gun applied Soudafoam Products.
