Fire Barrier Installation

Fire barriers we install

• Cavity barriers in walls, floors and external wall cavities, closing the void at compartment lines.
• Ceiling void and roof space barriers that continue compartment walls above the ceiling, where they are often missing.
• Service penetration seals around pipes, cables, ducts and trunking, using collars, wraps, pillows, batts and sealants matched to the service.
• Riser barriers at each floor, so a fire cannot travel up the service shaft.
• Linear joint seals where walls meet floors and ceilings.

Why fire barriers fail

Most missing or broken barriers are not from the original build. New cables, pipes and data runs are added over the years and nobody seals the holes behind them. A compartmentation survey finds these breaches, numbers them and marks them on a plan, so the repair can be priced and checked.

How we install and record fire barriers

1. Survey. We find every breach and gap in the barrier line, or work from your existing survey. 2. Tested systems. Each opening is sealed with a product tested for that type of service and wall or floor. 3. Photo record. Every barrier and seal is photographed before and after, and labelled with its location. 4. Handover pack. You get the photos, product details and a schedule of every seal for your fire risk assessment and insurer.
