With Soudal Soudafoam 2K X-tra two-component pu foam, you install interior doors and window frames with exceptional speed and stability. Thanks to its two-component chemical activation, the foam cures quickly and evenly across the entire volume without relying on ambient moisture. Because it exhibits no shrinkage or post-expansion once cured, your frames remain perfectly aligned without warping. This 400 ml aerosol can also provides outstanding thermal and acoustic insulation, making it ideal for reliably filling deep voids, pipe penetrations, and joints during installation and renovation jobs.
