Quick-setting gun grade fire-rated foam
EVERBUILD® B2 Gun Grade Fire Foam is a quick-setting one-part polyurethane foam with fire resistance properties. The foam expands on application 1.5 - 2 times its original volume. 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 °C to +25 °C, 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.
-
Economical in use - expands up to 50 times its original can volume.
-
Fills irregular and broad gaps where most conventional fillers would fail.
-
Possesses insulating and sound deadening properties.
