But whether legally required or not, we’d recommend them as a safety precaution. Using a fire and acoustic hood helps resist the spread of fire through the floors of a building and to reduce the transmission of noise to adjacent rooms and properties. It’s a requirement for all speakers that are installed below any habitable rooms and escape routes.MAINTAINING FIRE RATINGS The hoods maintain fire rating integrity of the ceiling to which they are fitted, thus enabling 30 minutes or 60 minutes of fire rating to be maintained. Tested at the UK Building Test Centre and complies with Part B and Part E of UK building regulations – reports are available on request.REDUCING SOUND LEAKAGE When a speaker is installed into a ceiling or wall it can help transmit unwanted sound, potentially into another property, even when the speaker is not in use. Adding these hoods effectively restores the acoustic integrity of the ceiling or wall. When the speaker is in use it can also reduce the rear transmission of sound by around 10dB over the mid to high frequency range. Preventing the transmission of low (bass) frequencies is a specialist field and may require substantial additional treatment. Specifications:Woven Glass Fabric: Thickness – 0.40mm, Weight/m² – 430 g/m²Warp count: 1360 d’texFinish: Starch weave lock SPONGE PROPERTIESPhysical form/appearance: Solid, voluminous material, more or less elastic.Specific gravity: 10-600 kg/m³Solubility in water: InsolubleOdour: None or mild odourFlash ignition point: Between 315ºc to 370ºcDecomposition temperature: Above 180ºcThermal energy: 28 000 KJ/kgStability and reactivity: The product is stable at temperatures between -40c and 12ºcAuto-ignition point: Between 370ºc to 427ºc (ASTM D 1929) TEST DETAILS Complies with Part B and Part E UK building regulationsIntegrity InsulationTrada FR 1739 240 mins 46 minsBTC 10891F 88 mins N/A EXTERNAL DIMENSIONSQi 50CF – Dia. 270mm, Depth 100mmQi 65CF – Dia. 290mm, Depth 100mmQi 80CF – Dia. 320mm, Depth 110mmQi 65RF – Dim. 270mm x 350mm, Depth 100mmQi 80RF – Dim. 320mm x 400mm, Depth 110mmQi 65 LCRF – Dim. 270mm x 540mm, Depth 110mm
