Cavity Barriers
Certified Cavity Barrier Installation for Complete Passive Protection
At Flamesafe Solutions Ltd, we provide expert installation and inspection of cavity barriers and fire curtains, vital components in preventing the hidden spread of fire and smoke within building voids. These systems are often overlooked but play a critical role in maintaining fire compartmentation in concealed spaces such as wall cavities, ceiling voids, lofts, and service risers.
Installed by Trained Professionals:
Our team is fully trained and understand correct specification and installation of cavity barriers and fire curtains, ensuring compliance with current fire safety standards. We work with third-party approved materials and follow rigorous installation practices to guarantee performance in real fire conditions..
Types of Barriers We Install
We offer solutions tailored to a wide range of building designs and void conditions, including:
- Open State Cavity Barriers - Designed to allow air flow and ventilation during normal use, these barriers expand when exposed to heat to seal the cavity and prevent fire spread—commonly used in ventilated facades and cladding systems.
- Closed State Cavity Barriers - Fixed barriers that permanently fill the cavity space, preventing the passage of fire and smoke without the need for activation—ideal for internal wall cavities or where no ventilation is needed.
- Fire Curtains for Ceiling Voids & Lofts - Installed within roof spaces, lofts, and ceiling voids, fire-resistant curtains compartmentalise hidden areas, slowing the spread of fire above occupied areas and helping preserve escape routes and property.
Why Cavity Barriers Matter
Fire can rapidly spread through unprotected cavities and voids, bypassing visible fire protection measures.
Properly installed cavity barriers and fire curtains:
- Compartmentalise concealed spaces
- Prevent vertical and lateral fire spread
- Party wall junctions and perimeter interfaces
Applications
