Injecta Fire Barrier
Fire Barrier are pleased to announce that we are the UK’s first approved installer in England of the patented Injectaclad system, which is a retrospectively installed cavity barrier system developed by leading fire protection experts.
Injectaclad is an acrylic based graphite sealant developed by leading fire protection experts. It is used to reinstate the fire resistance performance of wall and floor construction cavity details, where linear gaps are present within hidden voids that can allow fire and smoke to pass through from one compartment to another.
Injectaclad expands upon contact with heat and is considered as an intumescent or reactive
Negating the need to remove external facade systems
By negating the need to remove external façade of buildings, this installation system has significant cost reduction on existing premises where there is no existing fire barrier within the cavity or the original is found to be defective. The product is pumped into the cavity to the desired depth and width void using a patented method to form a linear cavity fire barrier utilising the systems reinforcing mesh and holding pin supports.
For more information please see our full detailed guide on the product which discusses how it works and the key benefits.
Injectaclad BS8414-1 Testing
External wall systems are assessed for combustibility and ignitibility by reaction to fire performance tests that measure the contribution to fire growth, not the ability of a system to resist the passage of fire against time in terms of insulation and integrity.
British and European fire tests will coexist. The British Standards were due to be withdrawn, however, as the UK are no longer members of the EU the British Standards will remain in place.
Injectaclad has been tested and approved to BS8414 (Part 1). This test methodologies allow full scale testing of external wall insulation systems on a solid substrate (Part 1)
The test procedure sets up an identical system to the actual external wall insulation system on the building and is installed on a main test wall 8 m in height, 2.6 m wide with a 1.5 m wide return wing.
A 2m x 2m combustion chamber is located in the base of the main wall and a wooden crib ignited in the chamber to simulate fire break out from a window or doorway and its propagation over the façade.
Thermocouples installed through and within the external wall insulation system at various heights on the walls constantly monitor temperature to determine external and internal fire spread over the 30-minute fire duration which is followed by a 30-minute post fire observation period.
