TENMAT fire rated enclosures have been designed to meet the building code and to help maintain the integrity of fire-resistance rated ceilings when penetrated by recessed lights, LED luminaires, fluorescent fixtures or in-ceiling loudspeakers.

Municipalities across the United States require fire-resistance rated ceilings, floors and walls for multi-story residential structures such as apartment buildings, student housing, schools, hospitals or hotels. The 2015 version of the International Building Code (IBC) addresses this issue explicitly in section 714.4.2:

“Where floor/ceiling assemblies are required to have a fire-resistance rating, recessed fixtures shall be installed such that the required fire resistance will not be reduced.”

In order to meet this fire code requirement, the ceiling must serve as an unbroken fire barrier, however cutting an opening in the ceiling to install a light fixture or junction box compromises the fire rating of the drywall ceiling. If the fire-rating of the ceiling membrane is not being restored, these openings in the ceiling would allow flames and smoke to spread in the unfortunate event of a fire.

TENMAT 1 and 2 hour UL fire rated light enclosures safely restore the ceiling’s integrity after holes have been cut for the fixtures or junction boxes, and maintain the fire code requirement for the building.
