BOSS Intumescent Fire Dampers allow the bi-directional movement of air through fire rated walls and floors. In a fire situation the slats in the damper intumesces and swells to many times the original size, closing the damper and forming a solid fire barrier. They are simple to install, easy to identify, and economical to maintain. The BOSS Damper has slats of foil-covered intumescent material with a rigid steel frame.
