Soudal Genius Gun Flexible Expanding Insulation Foam 750ml Blue

Soudal Straw Gap Filling Expanding Foam is a self expanding, ready-to-use, flexible polyurethane based and Freon free, meaning the foam is harmless to the ozone layer. The genius gun design is a patented trigger mechanism ensuring precise dosage and removing the need for an additional gun. The foam expands to 30 times the size of the can, forming an airtight, waterproof, soundproof and thermal insulating bond on most surfaces. This foam is an ideal insulator as it cures to become fully flexible and absorb the movements of the substrates without cracking. Ideal when filling gaps in your house like filling of joints between wall panels, filling openings between window frames and the surrounding constructions, filling wall cavities and pipe penetrations.
