The Soudal SWS Window & Door Gun Grade Foam is a high-performance polyurethane foam designed for airtight sealing, thermal insulation and acoustic protection around window and door frames. Part of Soudal’s renowned SWS installation system, this foam is trusted by window installers and builders across Ireland striving to meet modern airtightness and BER standards.
Once applied, it expands to fill gaps between frames and walls, creating a totally airtight, weather-resistant seal. This prevents draughts, heat loss, moisture penetration and sound transfer, key concerns in Ireland’s climate, where airtightness and insulation are essential for comfort and energy efficiency. It offers exceptional stability, strong adhesion to common construction materials, and long-term performance once fully cured.
Ideal for use in:
– new-build airtight homes
– retrofit window installations
– door frame sealing
– energy-efficient upgrades
– acoustic insulation applications
