FireBlox™ Non-Ventilated Cavity Fire Barrier has a A1 rated reaction to fire and is tested with SFS. Manufactured from plain stone mineral wool, it provides effective fire resistance for integrity (E) and insulation (I) for up to 120 minutes (EI120) within external cavity walls. The exact level of performance will depend on the orientation of the FireBlox™ and the construction of the external walls.

FireBlox™ is foil encapsulated and available in both cut-to size pieces to suit the cavity width, and in full slabs. It can also be supplied with integral damp proof course if required to suit a specific project. This product is designed for use within cavities of up to 600 mm wide and requires only 5 mm of compression when fitting.
