My recessed light is IC rated. Doesn’t that mean it is already fire rated?
No. IC–rated fixtures are designed and tested for direct contact with insulation, but are by themselves poor flame barriers. Most IC fixtures are made either from light sheet metal or aluminum that breaks down rapidly when in direct contact with fire. While IC-rated lights are constructed to avoid starting fires, “fire rated” lights and covers serve as a fire barrier in the event a fire has already started. Tenmat Fire Rated Light Covers fit most IC-rated lights and will maintain the fire rating of the ceiling.
