Fire resistant downlight covers for use in ceiling and floor constructions.
Downlight Fire Hoods are designed to reinstate the fire and acoustic performance of ceilings and/or floor constructions when penetrated by downlighters or blank openings if lights are removed for maintenance.
The Downlight Fire Hood is made from an intumescent flexible mineral wool material allowing it to be installed through the hole cut into the ceiling membrane. The fire hood also includes small ventilation holes, which allows hotter operating downlighters to ventilate, a small pre-cut hole for the light fitting cable to pass through and a steel clip to hold the hood in place. In the event of a fire the intumescent material will expand to enclose the ceiling cutout, cable and ventholes, providing effective fire resistance, for integrity (E) and insulation (I) for 30, 60 or 120 (EI 30/60/120) depending upon the ceiling and floor joist construction, even if the downlight is removed and replaced.
