813 Fenster Schaum

813 Fensterschaum is the product of choice for sealing perimeter joints on windows and roller shutter boxes, as it does not continue to expand after application. Since the one-component polyurethane foam adheres to almost all substrates and has excellent thermal and sound insulation characteristics, it is also ideal to use for foaming in structural connections compliant with applicable standards. The special valve makes it easier to work with a foam gun. The cured foam is semi-hard, predominantly closed-cell, and resistant to rot, moisture and temperatures between -40°C and +80°C.
