A fire-rated ceiling access panel is a specialized fixture installed in ceilings to provide access to various building systems, such as HVAC units, electrical wiring, and plumbing. These panels are designed to maintain the fire-resistance rating of the ceiling, which is crucial in preventing the spread of fire and smoke between different spaces. They come in various fire ratings, generally ranging from 1 hour to 3 hours, depending on the materials used and the certification standards they meet.
