TENMAT Firefly 109 Fire and Acoustic Socket / Switch Box Covers are a cost effective and simple solution for protecting electrical switch and socket boxes when fitted in fire and acoustic rated walls. The intumescent material fully encases the socket to provide an acoustic seal but in a fire situation it expands and seals the hole made for the sockets to limit fire spread for up to 120 minutes.
