\t\t\t

Everbuild B2 Expanding Firefoam Gun Grade is a quick-setting one-part polyurethane foam with fire resistant properties.

\t\t\t

This expanding foam can be applied by any expanding foam gun but is designed to be used with an Everbuild Professional Foam Gun.
\t\t\tThe foam expands on application to up to 50 times its original volume and meets the requirements of DIN 4102 Part 1 for Construction Materials; Class B2.
\t\t\tOnce cured, the foam can be cut, sawn or plastered over after only one hour providing the working temperatures (can and surfaces) are between +5 to +25 degrees Celsius (ideally 20 degrees Celsius).

\t\t\t

This product has a high degree of fire rating to slow down the passage of flames and smoke in comparison to standard B3 grades.
\t\t\tThis product is ideal for filling areas such as gaps around pipe entries through fire-rated walls, to provide a fire-rated seal around window and door frames, electrical wire chasing prior to plastering, where a fire rating is required, deep joints prior to applying sealant or plaster as well as irregular gaps in stone, brick, concrete or plaster.
\t\t\tIt is also suitable for insulating behind cladding to exterior walls, behind soffit and barge boards and even in automotive applications.
\t\t\tMeets the requirements of the test criteria for BS476 Part 20 when used as part of a fire-rated joint, use in conjunction with Everbuild Firemate intumescent sealant for maximum fire rating.
