What is Soudal Window System (SWS)? Soudaseal 215 LM sealant is a part of the Soudal Window System (SWS), which provides a weather resistant, airtight and insulated seal between window and door frames and their building structure. While Soudaseal 215 LM offers weather and wind protection on the outside, Acryrub SWS gives airtightness and damp protection on the inside, and Soadafoam SWS provides thermal and acoustic insulation in between. SWS can be used for new build, or renovations, and is compatible with all types of frame materials.
