With the Soudal Flexifoam Gun elastic pu gun foam, you reliably seal movement and expansion joints around window and door frames. Thanks to its permanent elasticity, the foam accommodates settling and structural movements without cracking or causing air leakage in your insulation layer. It provides excellent thermal and acoustic insulation, effectively reducing thermal bridges and structure-borne sound. The threaded connection for a standard dispensing gun allows you to apply the foam cleanly and accurately into cavities and vibration-prone service penetrations. This 750 ml can yields approximately 30 l of cured foam and bonds firmly to most building substrates.
