June 18, by Waterproof Caulking. Your building needs them both to protect the people working there and to protect the property itself. A firestop is a system that seals openings in walls with fireproof materials to make it more difficult for smoke and flames to spread from one room to another. Buildings are full of gaps that can allow a fire to spread. Joints between the roof and the walls, or between two walls, are small, but can allow a fire to spread if they are not properly sealed. Firestops are not used to prevent or put out a fire, but to slow down the spread of a fire.

Firestop & Fire Protection

Concrete masonry is widely specified for fire walls and fire barriers because it is noncombustible, durable and economical. Firestopping must be installed in accordance with code requirements to maintain fire and life safety. Choosing an appropriate firestopping system is a key component to a successful installation. The firestop system must be chosen from a building-official-approved listing service.
