Our growing trained teams of UK wide installers undertake fire stopping solutions to all service penetrations or voids in fire compartment walls to ensure compliance with the specified fire strategy and Part B building regulations.

Unrivalled knowledge installing fire-rated compartmentation within buildings and finding the correct solution for your fire stopping requirements.

Investing in commercial firestopping systems for your building will ensure the containment of a fire at its source so as to limit its spread, protect escape routes against heat and smoke and protect the structure of the building to prevent it from collapsing.

We pride ourselves in work in partnership with our clients, architects, contractors and building inspectors to ensure that we provide appropriate, cost-effective, fully designed and engineered fire stopping systems tailored to each building.

We install both vertical and horizontal firestops through floors and walls, and these are primarily used to seal penetrations formed for the passage of services such as drainage, pipes, cables.

ATOL Fire provides a comprehensive range of compartmentation works to protect people and buildings in the event of a fire. Moreover, all of our work is backed up by intense audits such as FIRAS to ensure the quality and standard of work.

The aim of Compartmentation is to limit the rapid spread of fire.

By dividing building premises into “fire compartments”, fire is contained by forming a barrier against smoke, heat and toxic gases. Fire Compartmentation is designed to contain the fire in the area of origin, providing protection for the building and for its occupants. Fire Compartmentation is the most effective mean of limiting fire damage before the fire brigade arrives. The benefits of compartmentation are: limiting fire damage, allowing further fire prevention systems to be installed, increased fire protection for a limited period of time.
