Ceiling Radiation Dampers are available in butterfly style and curtain style. They are used to protect HVAC openings in fire-rated horizontal ceiling assemblies. A ceiling damper closes automatically to restrict the passage of heat. Operated by a fuse link, these dampers come spring-loaded and are available with an easy-access assembly. This allows the consumer more access to the damper in the event that maintenance needs to be performed or the fuse link requires replacing. Ceiling dampers are also applicable for installation in boots and register boxes. We fabricate insulated and non-insulated boxes as well as 90°, End and Straight boots.
