Installers predict 2024 will be record year for retrofitted cavity fire barriers

Passive fire barrier specialist, Injecta Fire Barrier, believe the next 12 months could be the biggest growth period to date for retrospectively fitted cavity fire barriers in commercial and residential buildings.

New regulations introduced by the UK government in the wake of the Grenfell Tower tragedy have put pressure on building owners to take action to stop the potential spread of fire, particularly through external cladding and facades. 52 Developers have signed a building safety repairs pledge to remediate life critical fire safety works in buildings over 11 metres. Working with leading Fire Safety Specialists, Injectaclad have created a system which can be retrospectively installed to stop the spread of fire and smoke throughout the external building cavity.

As a result, the number of enquiries is significantly on the increase. “Using Injectaclad is such a compelling option when balanced against the cost and disruption of removing the existing cladding” says Steph Snooks, Business Development Manager at Injecta Fire Barrier.

Injecta Fire Barrier is an independent authorised installer of the Injectaclad solution which consists of an acrylic-based graphite sealant injected into wall and floor cavities, to reinstate the fire-resistant performance of rigid and flexible wall and floor constructions where a retrospective cavity barrier is required.

The product rapidly expands up to 20 times its size upon contact with heat to create a fire-resistant barrier which stops the passage of flames and smoke.

This is particularly effective in multi-storey buildings where it can help limit the risk of smoke and fire spreading horizontally and vertically throughout the floors.

“Cost and disruption are barriers to improving fire protection, but the patented Injectaclad solution, significantly reduces the impact of these factors over using traditional cavity fire barrier remediation methods. We believe the market for retrofitted cavity fire barriers will grow significantly throughout 2024” adds Steph.

In the wake of Grenfell, the UK government revised high-rise building regulations to force owners to reduce the risk of fire spreading via cladding and voids in the cavity.

In June 2020, the UK government estimate of 1,700 buildings in England alone were affected and the Parliamentary Housing Committee noted a further 9,600 buildings were likely to have combustible cladding.

Rather than removing non-combustible cladding, Injectaclad can be swiftly injected both horizontally and vertically to compartmentalise the exterior building façade.

In the event of a fire, Injectclad has a fire resistance rating of 120 minutes, providing occupants with a two hour window to safely exit the building.

“As well as lower cost and less disruption, building owners are also drawn to the environmental benefits as it eliminates the need to remove and dispose of cladding, facades and existing insulation. It reduces noise and dust pollution and volume of waste to landfill. The product is manufactured in the UK.” adds Steph.

Once installed, the Injecta Fire Barrier is long-lasting and resistant to moisture, making it suitable for use in both dry and damp environments.

“Fire is devastating to lives and livelihoods and this year will hopefully see significant progress towards ensuring a tragedy like Grenfell does not occur again” concludes Steph.
