What is the primary function of a ceiling radiation damper?

The primary function of a ceiling radiation damper is to limit heat transfer. These dampers are specifically designed to prevent the passage of heat and smoke through ceiling openings during a fire. By restricting the movement of heat and smoke from one area to another, ceiling radiation dampers help maintain the integrity of fire barriers and protect exits, ultimately allowing for safe evacuation and effective fire suppression. This function is crucial in maintaining compartmentalization within a building, which is essential for the safety of occupants and the effectiveness of fire response efforts.
