Sika Everbuild B1 Gun Grade Fire Foam 750ml

Summary

The Sika Everbuild B1 Gun Grade Fire Foam is a quick-setting, fire-rated, one-part polyurethane expanding foam designed for use with a professional foam gun. Ideal for sealing and filling around pipes, door frames, window frames and penetrations in fire-rated walls and partitions, it provides a high-performance fire barrier alongside excellent insulating and sound-deadening properties. At 750ml, the can yields 35 litres of cured foam, making it highly economical in use.

Features

• Quick-setting formulation expands to fill cavities and can be cut, sawn or plastered over after approximately one hour of curing.
• Fire rated up to 4 hours in certain joint configurations, providing a reliable passive fire protection barrier.
• Meets the stringent requirements of DIN 4102 Part 1 for Construction Materials, Class B1, and BS 476 Part 20.
• Expands on application to yield up to 50 times the can contents, ensuring economical and efficient coverage.
• Slows the passage of flames and smoke to a significantly higher degree than standard B3-grade foams.
