PFP division
Passive Fire Protection (PFP)
Making existing buildings safe from fire, without removing the façade.
A cavity fire barrier has one job. It closes the gap behind the façade so that a fire stays in the compartment where it started. When that barrier is missing or defective, the cavity becomes a hidden route for fire and smoke to travel across and up a building, out of sight of the people living there and the crews fighting it.
Since Grenfell, building owners carry clear legal duties under the Fire Safety Act and the Building Safety Act to deal with that risk. For years the only answer was to take the wall apart: strip the cladding, pull out the insulation and rebuild, with the cost, waste and months of disruption that brings. Many buildings have been left stuck between a known risk and a remedy nobody wants.
Injectaclad breaks that deadlock. It is pumped into the cavity through small openings in the outer wall, forming a solid barrier along each compartment line beside the existing insulation. In a fire, the graphite-based material expands into the space the burning insulation leaves, sealing the cavity against heat, smoke and flame. The façade stays on and residents stay in their homes.
The Group owns the product, the patent and its own installer, Injecta Fire Barrier, so it captures value from both supply and installation.
- 150+ Buildings remediated to date with Injectaclad across the UK and Ireland, from two to twenty-six storeys
