For plastic lead throughs or metal pipes The BIS Pacifyre® MK II Fire Stop is a single part fire sleeve which seals a pipe lead-through with a grommet type seal making it fire resistant and smoke tight. Only one BIS Pacifyre® MK II Fire Stop is required to seal off the aperture between the pipe and the wall or ceiling making it fire resistant and smoke proof. Escape routes and rescue access therefore remain unobstructed for longer and free of smoke, allowing occupants to vacate the building in good time and in a safe manner.
