Everbuild 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 +25oC, ideally 20°C.
High degree of fire rating: slows down the passage of flames and smoke in comparison to standard B3 grades.
Quick setting - can be cut, sawn or plastered in 1-hour is economical in use as it will expand up to 50 times its original volume.
Everbuild EVBB2FIREGUN is gun operated and is ideal for filling:- 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 also irregular gaps in stone, brick, concrete or plaster.
Everbuild is ideal for fixing:- door frames, timber structures, windowsills and thresholds and window frames.
Also for insulating:- behind cladding to exterior walls, behind sofit and barge boards and even in automotive applications.
