Fire collars 

If your walls or floors have cables, pipework and ducts, you’ll need a specialised solution to maintain their integrity. That’s because their fire rating can be reduced in a fire. When they melt, they create gaps through which smoke and fire can travel. Fire collars help seal off this spread.

Fire collars

A fire collar is a fire-resistant fitting that you’ll need when building services have taken place and an area has been penetrated by cables, ducts and pipework. These can reduce the fire rating of the wall or floor, as pipes can melt, leaving a void into adjoining compartments.

Fire collars create an insulating barrier thanks to a retaining ring with an intumescent material that expands under heat. The result is a fire-resistant seal with up to four hours’ fire protection.

Benefits

• Up to four hours’ fire resistance
• Compatible with many plastic pipes
• Fast installation
• Cost-effective
• Water resistant
• Maintenance free.

Typical applications

Fire collars are typically used to maintain the integrity of plastic pipework that passes through fire-resistant walls and floors.

Fire sleeves

 

Fire sleeves serve the same purpose as fire collars but need no mechanical fixing. They also have the added benefits of both noise insulation and thermal insulation. We use them in plastic and metal pipework and rectangular vent ducts, conduits and trunking.

 

Fire sleeves wrap around the pipes. In a fire, they expand to seal the resultant gaps. As plastic pipes melt, they continue to close the gap, offering up to two hours’ fire resistance.

 

Benefits

 

• • Up to two hours’ protection from fire and smoke
  • Acoustic insulation
  • Thermal insulation thanks to reinforced aluminium-foil facing that helps prevent condensation forming

 

• Fast installation, so minimal disruption.

 

Typical applications

We install fire sleeves around metal and plastic pipes. They create a penetration seal that maintains the fire-resistance of walls and floors with gaps cut out for pipes.

 

Intumescent wraps

Plastic pipes leave gaps in fire-rated walls and floors, through which fire and smoke can pass when they melt. Intumescent pipe wraps offer the same cost-effective solution as fire sleeves but with more flexibility and no size restriction.

 

The wraps fit most trunking sizes. They wrap around the pipework and we fix them in place with self-adhesive strips. In a fire, the wraps expand to fill the gap left by burnt-out plastic. Giving you up to four hours’ fire protection.

 

Benefits

 

• Four hours of fire and smoke resistance
• Fits most sizes of pipe
• Fast installation with no mechanical fixings
• Water-resistant, so no problem with hoses and sprinklers
• Low maintenance – fit and forget.

 

Typical applications

Intumescent wraps expand to fill the gaps left by melted plastic piping in plasterboard walls, ceiling and floors
