The BluCube Universal Fire and acoustic speaker hood is just that - a fire hood that also performs as an effective acoustic barrier to sound leakage from behind an in-ceiling speaker to rooms above. Building regulations state that if you cut an aperture in the ceiling of a room, for instance to fit an in-ceiling speaker, you must ensure that the fire integrity of the ceiling is maintained. Tested and assessed by Warrington Fire, a renowned and accredited UK testing facility, to British Standard 476 Part 21 in a standard domestic timber-joist and plasterboard ceiling, the BluCube Universal Fire Hood comfortably performed to such requirements. Featuring a double-skin of intumescent fabric sandwiching fire-proof foam and with a uniquely designed internal collar providing easy-installation, improved fire and acoustic absorbing performance and protection of the speaker from dust ingress, the BluCube UFH01 is a must for every installation. Plus its one-size-fits-(nearly)-all design means it's likely to be the only hood you need.
