Astroflame's Socket Box Inserts, are manufactured from halogen free, low smoke, fire resistant, mineral fibre material and are designed to maintain the fire performance of partition (stud) wall constructions when penetrated by steel or plastic electrical back boxes. The insert will also provide resistance to the passage of sound and air movement.

In the event of a fire the Socket Box Inserts mineral fibre material will prevent the fire passing through the electrical back box aperture, providing effective fire resistance, for integrity (E) and insulation (I) from 30 to 120 minutes (EI30 to EI120) depending upon the wall construction.
