description.
The Acoustic Hoods also add mass and sound absorption on top of the lighting unit and improves the sound insulation that the inclusion of an inset light usually degrades. Acoustic tests have shown that a ceiling with down lighters with acoustic hoods installed performs to within 1dB of the equivalent ceiling with no holes at all.
Down lighters in ceilings are now widely used. In multiple occupied buildings, most ceilings are subject to fire regulations and where applicable the ceiling construction needs to be fire rated.
However, once a hole has been made in the ceiling for a down lighter, the integrity of the construction and it's ability to perform in a fire can be reduced significantly. To combat this we have introduced an acoustic hood that not only compensates for the hole in the ceiling but is also fire resistant and intumescent to provide the utmost protection for holes created by the installation of a down lighter and to allow for maximum ease of fitting.
In a fire situation the cover expands internally to fill all the available space with a highly insulating fire resistant char. Thus, the fire is unable to penetrate the hole and the cover is able to give additional fire protection to the ceiling void to reduce the chance of heat build up and ignition of flammable materials such as accumulated dust.
These hoods are available in many sizes to suit the cut out space.
WE WOULD ALWAYS ADVISE AGAINST CUTTING HOLES IN THE CEILING TO FIT LIGHTS AS IT ALLOWS SOUND TO PASS THROUGH IT MUCH MORE EASILY. IF YOU MUST USE DOWNLIGHTERS PLEASE MAKE SURE YOU FIT THESE HOODS ALONG WITH OUR OTHER SOUND INSULATING MATERIALS.
