The FF109X is the only two hour UL tested and approved fire barrier that can be used with a wide range of recessed lights to effectively prevent the spread of flames through a ceiling opening. Once a hole is made in the drywall to install recessed lights or speakers, the integrity of the construction and its ability to perform in a fire is reduced significantly, creating a potential fire hazard. This is the reason why the International Building Code states: “Where floor/ceiling assemblies are required to have a 1 or 2-hour fire resistance rating, recessed fixtures shall be installed such that the required fire resistance of the ceiling will not be reduced” The FF109X is two hour approved for every major ceiling assembly including gypsum, sheetrock, drywall, acoustical tiles and suspended ceilings with any joist spacing up to 24 inch on center. The enclosure is made out of an intumescent material which will be activated in case of a fire, stopping both, flame spread and heat transmission for two hours. Tenmat 2 Hour Fire Rated Light Covers are UL tested and approved for use with IC-rated recessed incandescent, fluorescent, LED light fixtures. TENMAT Fire Rated Light Covers can be used with most light manufacturer’s models and are suitable for new construction as well as remodel projects. In addition to its fire protection capabilities, the FF109X also exhibits excellent thermal and acoustical insulating properties to save energy and reduce noise. The flexible and lightweight nature of the covers makes installation quick and easy, reduces the stress put on the ceiling and significantly reduces labor costs compared to standard dry-walled box constructions.
