EVERBUILD FIREFOAM B2 GUN GRADE  is a quick setting one part polyurethane foam with fire resistance properties. The foam expands on application to up to 50 times its original volume and meets the requirements of DIN 4102 Part 1 for Construction Materials and BS476 Part 20. Fire rated up to 2 hours in certain joint configurations. Copies of the independent test certificate, Warrington fire report number 160902 are available on request.

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 to +25^oC, ideally 20^oC.
