About Our Products

Built-In Fire Safety with Passive Fire Protection Products

Our passive fire protection products stop smoke and flames from spreading through openings behind wall cavities or through openings where pipes, wires, duct, etc. pass through the walls, ceilings and floors. These special materials are inactive under normal temperature conditions but will react when exposed to heat. Upon exposure to heat, they will quickly expand and seal off the openings, thereby serving to contain the fire and protect the basic structure of the building. This affords the people time to escape and assists the fire department in bringing the fire under control.
