Restricting a fire and it’s components, flames, smoke and toxic gases, to its point of origin is a crucial component of effective fire stopping and passive fire protection of a building. It is important to preserve structural integrity of building compartments where communications, services, utilities, etc go through fire resisting walls. Key areas to consider are;

- construction linear joints
- apertures and penetrations via floors and walls
- cavity barriers
- service openings (e.g Ducts), within wall surfaces and floors
- combustible pipes and cables

There are a wide range of passive fire protection solutions and Fire-stopping products that can be utilised to effectively seal penetrations, apertures and openings within a building’s fire compartments.

These include; fire batts, covers, mastic sealants, fireboards, collars, mortars, fire curtains, putties and pillows.
