Everbuild Fire Foam B1 750ml

Everbuild B1 Handheld Fire Foam is a quick-setting, fire-rated one-part polyurethane foam designed for sealing, filling, and insulating applications that require fire resistance. It expands on application to up to 50 times its original volume, providing effective insulation and fire protection. Fire ratings can reach up to 4 hours in certain joint configurations. When cured, it can be cut, sawn, or plastered over after approximately one hour. Suitable for gaps around pipe entries, window and door frames, electrical chasing before plastering, deep joints, and irregular gaps in stone, brick, concrete, or plaster. It can also be used behind cladding and around soffits and barge boards. For maximum fire rating, use in conjunction with EVERFLEX FIREMATE intumescent sealant. Expansion is 40 litres from a 750 ml can. The product is compatible with concrete, masonry, and plaster surfaces.
