Everbuild Sika Fire Foam B2 Hand Grade Aerosol 750ml - 488717

The Everbuild Sika Fire Foam B2 is a quick-setting, one-part polyurethane foam designed for fire resistance. Expanding up to 50 times its original volume upon application, this foam 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, provided the working temperatures (can and surfaces) are between +5 to +25°C, ideally at 20°C. Its high degree of fire rating effectively slows down the passage of flames and smoke compared to standard B3 grades.

This hand-operated foam is ideal for:

• Filling gaps around pipe entries through fire-rated walls
• Providing a fire-rated seal around window and door frames
• Electrical wire chasing prior to plastering
• Filling deep joints before applying sealant or plaster
• Insulating behind cladding to exterior walls

Perfect for fixing door frames, timber structures, windowsills, thresholds, and window frames, it is also suitable for automotive applications.
