Fire Seal For Cable

A fire seal for cable is a passive fire protection system designed to prevent the spread of fire, smoke, and toxic gases through openings created by cable penetrations in walls and floors. When electrical, data, or communication cables pass through fire-rated barriers, they leave gaps that can compromise the building's fire resistance. Fire seal systems restore the fire rating of these barriers, helping to contain a fire within its area of origin and providing occupants with more time to evacuate safely.

Fire cable seals are made from specialized fire-resistant materials such as intumescent sealants, firestop putty, mortar, pillows, wraps, or blocks. Many of these materials expand when exposed to high temperatures, sealing gaps around cables and preventing flames and smoke from passing through. These systems are widely used in commercial buildings, industrial facilities, hospitals, schools, data centers, and residential buildings.
