Fire stopping, also known as compartmentation, is a fundamental part of passive fireproofing. It refers to the process of filling openings and joints between walls and floors with fire-resistant material, inhibiting the spread of fire between ‘compartments’ within a building.

.

Fire stopping is also to seal around gaps between fire resisting constructions, e.g. the linear gap between a wall and the floor above, in order for construction to form a complete barrier to fire and smoke spread.

​

Firestops are used in:

• Electrical, mechanical, and structural penetrations

• Unpenetrated openings (such as openings for future use)

• Re-entries of existing firestops

• Control or sway joints in fire-resistance-rated wall or floor assemblies

• Junctions between fire-resistance-rated wall or floor assemblies

• Head-of-wall (HOW) joints, where non-load-bearing wall assemblies meet floor assemblies

​

RF Fire & Security Ltd are able to offer our clients a range of versatile fire stopping systems to maintain compartmentation where mechanical and electrical services pass through walls and floors. We are able to offer assistance with Fire Strategy where necessary and will always offer the most suitable, cost efficient product.

​

When we have completed a fire stop we record, label & sign off each one.  Each label has our company details together with installer name, date of fire stop, drawing reference & fire rating achieved.  We know that it is likely that services will be passed through our fire stops in the future but by looking at the label a client will be able to make contact with us and we can make the fire stop good, returning the integrity and fire rating
