What does a firestop system primarily consist of?

A firestop system is designed to prevent the spread of fire, smoke, and heat through openings and penetrations in walls, floors, and ceilings. The primary components of a firestop system include various sealing materials that create a barrier to protect against fire. These materials can be caulks, mortars, collars, putty pads, and intumescent products, which expand when exposed to heat, sealing off the gaps.

These sealing materials are essential because they must be compatible with the substrates they are used on, as well as the types of penetrations they are sealing. Effective firestop systems are engineered to maintain the integrity of the fire-rated assemblies, ensuring compliance with safety codes and standards.

The significance of focusing on the components of the firestop system lies in their role in fire protection strategies. By utilizing appropriate materials, the firestop system can effectively restrict the passage of fire and smoke, thereby protecting life and property in the event of a fire.
