Provides an effective acoustic barrier between fan / vent and ceiling.
This sleeve has been developed to provide maximum protection for holes created by the introduction of the most popular sizes of polymeric recessed ceiling fans and vents with minimal installation time.
In a fire situation, the sleeve expands internally to crush the spigot of the fan / vent and create an effective barrier against both heat and flames. Unlike other intumescent materials the sleeves do not need additional support and will only expand inwards.
