Air sealing is one of the simplest and most effective ways to stop fire and smoke from spreading through hidden pathways inside a building. By closing off gaps, penetrations and joints, we reinforce your building’s compartmentation and keep escape routes safer for longer.

Our expert installation ensures that fire compartments remain effective under all conditions.

How Air Sealing Improves Fire Safety

Prevents Fire & Smoke from Travelling

Unsealed gaps around pipes, cables and joints act like fast-track routes for smoke and heat. Proper air sealing blocks these pathways and slows the movement of fire through walls, floors and voids.

​

Strengthens Compartmentation

Fire compartments only work when they’re properly sealed. Even a small opening can compromise a fire-rated wall or floor. Our air sealing ensures those compartments stay intact and perform as designed.

Buys Crucial Minutes for Evacuation

By limiting smoke spread, air sealing helps keep escape routes clear for longer, giving occupants more time to get out safely.

Creates Safer Conditions for Firefighters

A sealed building keeps fire more contained, giving emergency responders a more controlled environment to work in.

Key Areas We Seal

Service Penetrations

Pipes, electrical conduits, ductwork, cable trays — any service passing through a fire-rated barrier needs proper sealing.

Construction Joints

Where walls meet floors, ceilings and partitions. These junctions often hide small gaps that can quickly break compartmentation.

Frames & Perimeters

Door frames, window frames, access panels and other openings that commonly develop high-risk voids over

time.

How We Seal

• Fire-Stopping Products: Use of intumescent seals, silicone, and fire-rated fillers.

• Comprehensive Coverage: Sealing gaps around pipes, ducts, and cables to maintain compartment integrity.

• Compliance: Installed to meet UK fire safety regulations.

​

Applications

• Roof voids, floor voids, and service risers.

• Around mechanical and electrical penetrations.

• New build and refurbishment projects.
