Why Fire Stopping?

Fire stopping is a form of passive fire protection, involving the sealing of any openings that could lead to the spreading of fire, smoke, and heat, throughout a building. Fire stopping is an essential method for protecting a building and any occupants within it from the spreading of fire. 

Penetrations and openings faced

Part of implementing the correct type of fire stop, is understanding the different kind of openings and penetrations faced in a premises. Once there is an understanding for these different types, there can be an understanding for the specific type of materials required to fill that particular opening, penetration or joint.



The  most common types of openings faced in a premises

 - Unpenetrated openings, involving openings for future use

- Head of wall joints where wall assemblies combine with floor assemblies 

- Areas between fire resistance rated walls or floor assemblies 

- Re-entries where previous unsuccessful fire stops will be found

- Any structural, mechanical, or electrical penetrations that can be found within a building

Types of Fire Stopping materials

There are multiple types of fire stops that can be installed to help ensure that the fire resistance of a wall, or floor assemblies remains continuous, whilst also preventing the spread of fire by filling openings with the correct fire-resistant materials.

Fire Sealants / Gap Fillers 

This type of fire stopping offers expandable properties when placed under high temperature conditions such as a fire. Perfect for the sealing of any slight openings or joints within a buildings envelope.

Fire Collars

This type of fire stopping uses intumescent properties to surround pipes and other openings, swelling up when placed in high temperatures such as fires, and smothering any heat, smoke, or flames before they can pass through into other compartments.


Fire Covers

This type of fire stopping is best for preventing fires in fire rated suspended ceilings that derive from luminaires. In high temperatures the fire cover will quickly swell to fill all the internal space with its fire resistant material.


Fire Sleeves

This type of fire stopping involves fire resistant sleeves that are designed specifically to fit in between the gaps left by pipes and wiring that pass through fire rated walls or ceilings. When in high temperatures such as fire situations, the sleeve will expand to fill any available space left, when specifically faced with plastic pipe work, the sleeve will completely seal off the pipe.

What does Fire Stopping involve?

The containment of the spreading of fire by implementing fire resistant compartments, which subdivide a building (vertically or horizontally). Buildings must ensure that any openings and gaps are fitted with the appropriate fire stopping materials to restrict both lateral and vertical fire spread.
