Sika Everbuild B2 Gun Grade Fire Foam 750ml - Class B2 Fire-Resistant Expanding Foam

Summary

The Sika Everbuild B2 Gun Grade Fire Foam is a quick-setting, one-part polyurethane expanding foam with fire-resistant properties, designed for professional gun application. It meets the requirements of DIN 4102 Part 1 for Construction Materials at Class B2, making it suitable for use wherever a fire-rated seal is required. Ideal for contractors working on fire-rated walls, door and window frames, and pipe penetrations.

Features

• Quick-setting formulation cures within one hour, allowing the foam to be cut, sawn, or plastered over promptly after application.
• Meets DIN 4102 Part 1, Class B2 fire classification for construction materials.
• High degree of fire rating significantly slows the passage of flames and smoke compared to standard B3-grade foams.
• Expands on application 1.5-2 times its original volume in the cavity, and yields up to 50 times the original can volume overall.
• Fills irregular and broad gaps where most conventional fillers would fail.
• Possesses thermal insulating and sound-deadening properties as additional benefits.
• Gun-operated design ensures precise application and allows the gun to be left attached between uses.
