Fix Factory fire rated switch/socket inserts offer maximum protection for penetrations created by the introduction of both single and double recessed switch/socket boxes and to allow ease of fitting. Fire Socket Inserts are an alternative firestop to intumescent putty pads.
A recessed switch or socket presents an easy path for fire and smoke to spread from room to room. In a fire situation the insert expands internally to fill all of the available space in the socket with a highly insulating char. Fix Factory Fire Socket Inserts are 2 hour fire rating tested to BS476 part 20/22:1987 for both integrity and insulation.
