What are Cavity Barriers in London?
Cavity barriers are passive fire safety measures that are put in place inside cavity walls, floors, and ceilings to stop smoke and fire from spreading. They serve as fire-resistant partitions in hidden areas.
In London, fire cavity barriers are a legal requirement in many types of buildings and must meet strict safety standards. Professional cavity barrier installation in London ensures compliance and reduces risk to life and property.
These barriers are crucial for stopping the passage of flames and smoke through linear cavities. Fire barriers in cavity walls are designed to compartmentalise a fire and slow its progress, giving occupants more time to escape and emergency services more time to respond.
Our fire stopping cavity barriers are chosen and installed with precision, ensuring compliance with BS 9991 and BS 9999 standards. The building’s structural integrity in the event of a fire is also enhanced by strategically positioned linear cavity firestops. Whether you require fire stop cavity barrier solutions for residential, commercial, or mixed-use properties, we’ve got you covered.
Why is Cavity Barrier Installation in London Important?
Installing cavity barriers in London is not just a regulatory necessity – it’s a life-saving solution. London’s dense urban landscape and varied building designs increase the risk of fire spread via hidden voids. Expert cavity barrier installation guarantees your property’s structural integrity and adherence to the law.
