What is a fire break in a wall?

A fire break, also known as a fire stop, is a flame-retardant material placed within the walls to help contain a fire. In constructing these balloon-frame homes, the walls often are left hollow from the basement to the attic, allowing fires to vent and spread rapidly from floor to floor.

What is a firestop in construction?

How does a firestop collar work?

How do Fire Collars Work ? Once the pipe starts to deform, the intumescent material in the Promat fire collar expands, closing off the plastic pipe. This intumescent material forms an insulating barrier which reduces heat transfer between compartments and closes off any gaps to stop the spread of smoke, fire and gas.

Why is fire stopping important?

Fire-stopping is an essential part of passive fire protection, which is why it is so important that it is installed by trained professionals, which will ensure that the system can be given a rating of up to four hours fire protection.
