Everbuild B2 Expanding Firefoam HandHeld Aerosol Fire Rated Foam 750m

Everbuild EVBB2FIREHAND Firefoam B2 is a quick-setting one part polyurethane foam with fire resistant properties.
The foam expands on application to up to 50 times its original volume and meets the requirements of DIN 4102 Part 1 for Construction Materials; Class B2.
Once cured, the foam can be cut, sawn or plastered over after only one hour providing the working temperatures (can and surfaces) are between +5 to +25 degrees Celsius (ideally 20 degrees Celsius).

This product has a high degree of fire rating: it slows down the passage of flames and smoke in comparison to standard B3 grades.
This product is hand operated and is ideal for filling areas such as gaps around pipe entries through fire-rated walls, to provide a fire-rated seal around window and door frames, electrical wire chasing prior to plastering, where a fire rating is required, deep joints prior to applying sealant or plaster and also irregular gaps in stone, brick, concrete or plaster. Everbuild Firefoam is ideal for fixing door frames, timber structures, windowsills and thresholds and window frames. It is also suitable for insulating behind cladding to exterior walls, behind soffit and barge boards and even in automotive applications.
