A quick-setting, fire-rated, handheld foam
EVERBUILD® B1 Handheld Fire Foam is a quick-setting one-part polyurethane foam with fire-retardant properties. The foam expands on application to up to 50 times its original volume and meets the test criteria BS476 Part 20; Class B1. Fire rated up to 4 hours in certain joint configurations. Once cured, the foam can be cut, sawn or plastered over after approximately one hour.
