Firebreak Service Transits comprise a range of circular and rectangular devices designed to be installed in fire resistant walls and floors where cables and other services are required to penetrate. Under fire conditions the foam plugs at each face of the transit restrict the passage of smoke whilst the intumescent material within the transit expands to form a durable plug around the services maintaining the fire integrity and insulation performance of the floor or wall.
