2GANG 35MM FIRE ACOUSTIC LINER

Astroflame Double Socket Box Insert is used to restore the fire rating of a wall. This design also restores the acoustic and thermal performance of the wall and its air-tightness. Insert is quick and easy to fit in comparison with traditional putty pads. Once a hole is made in the wall for a recessed switch or socket box, the integrity of the construction and its ability to perform in a fire can be significantly reduced. The acoustic performance of the wall is also affected and air leakage will increase. Air leakage allows heat loss and noise transmission. A single socket can leak over 3.5 cubic metres of air per hour and the combined air leakage of all the sockets in a room can create significant thermal loss. The material used to construct the socket insert is a good insulator, which further prevents heat loss and maintain insulation continuity of the wall. Acoustic performance is good, being rated at -67dB. 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 product is designed to fit common plastic/metal single/double socket box sizes. Simple and fast mechanical fixing, no adhesives, no mess. Replaces time consuming plasterboard lining of sockets/switches. The Socket box insert can be removed and replaced if additional wiring is required. Unique flanged design holds the socket box insert in place during a fire.
