Astroflame Fire & Acoustic Mounting Box Seals  

The Astroflame fire and acoustic socket box inserts are easy to install and are designed to restore the fire rating of a wall otherwise compromised by apertures and gaps following the fitting of socket boxes.

The socket box inserts are quicker and easier to fit that traditional putty pads. In a fire the inserts flanged design ensures that the fire resistant material remains in place to limit the spread of fire through the socket penetration.

This design also restores the acoustic and thermal performance of the wall and its air-tightness.
