Passive Fire Protection: Fire Doors, Compartmentation, and Fire Stopping from Tower Fire Group
Tower Fire assesses, installs, and inspects passive fire protection measures for businesses, landlords, and property managers across the UK. From fire doors and intumescent seals to compartmentation surveys and fire stopping, every service is carried out by a team with genuine, frontline fire service experience.
Under the Regulatory Reform (Fire Safety) Order 2005 and Building Regulations Approved Document B, the responsible person must ensure a building’s passive fire measures are in place, correctly installed, and properly maintained. A single unsealed penetration, a damaged fire door, or a compromised compartment line can put the entire building at risk.
What Is Passive Fire Protection?
Passive fire protection refers to the fire safety measures built directly into the fabric of a building. Unlike active systems such as alarms and sprinklers, which respond when triggered, passive measures work continuously without power or activation.
Examples include fire-resistant walls, floors, and ceilings, fire doors fitted with intumescent seals, fire stopping around service penetrations, and intumescent coatings applied to structural steelwork. Together, these elements divide a building into fire-resistant compartments, slow the spread of fire and smoke, protect means of escape, and buy critical time for evacuation.
Both passive and active fire protection are required for a complete, compliant fire safety strategy. Active systems detect and respond. Passive systems contain and slow.
Our Passive Fire Protection Services
Tower Fire Group provides a full range of passive fire protection services for commercial, residential, and mixed-use buildings across the UK.
Why Fire Compartmentation Is Critical to Building Safety
Fire compartmentation divides a building into separate, fire-resistant zones. When intact, a fire starting in one area is contained at source, escape routes remain clear, and the fire service has time to intervene effectively. When it fails, fire and smoke can spread rapidly throughout a building.
Compartmentation failure is rarely caused by poor original construction. More often it results from changes made over time: service penetrations left unsealed after maintenance works, fire doors wedged open or fitted with incorrect hardware, and refurbishment works that cut through fire-rated walls and floors without proper reinstatement.
A professional passive fire protection survey from Tower Fire Group will identify every breach, weakness, and area of concern across your building, with a full written report and a prioritised schedule of remedial works.
Fire Stopping: Sealing Penetrations and Restoring Compartment Integrity
Every pipe, cable, duct, and conduit that passes through a fire-rated wall or floor creates a potential route for fire and smoke to travel. Fire stopping UK specialists use tested, rated materials to seal those penetrations and restore the fire resistance of the surrounding structure.
Tower Fire Group carries out fire stopping installations using the full range of rated systems, including intumescent mastic, fire batts, pipe collars, cable transit systems, and linear joint seals. Every installation is fully documented with product data sheets and a certificate of completion for your fire safety records.
Fire Door Installation and Inspection
Fire doors are one of the most critical components of any passive fire protection strategy, and one of the most frequently found to be non-compliant. A fire door that does not close correctly, has a damaged intumescent seal, or is fitted with the wrong hardware offers little meaningful protection in an emergency.
Our fire door installation UK service covers the supply and fitting of FD30, FD60, and smoke-rated door sets to BS 8214 standards. We also carry out full inspections of existing fire doors, producing itemised reports detailing the condition of every door, frame, seal, closer, and hinge, with a clear schedule of required remedial works.
Who Needs a Fire Risk Assessment?
All non-domestic premises in the UK are subject to the fire safety requirements of the Regulatory Reform (Fire Safety) Order 2005, which includes maintaining adequate passive fire protection. Residential buildings with two or more dwellings are also subject to the Fire Safety (England) Regulations 2022, which introduced specific duties around fire door inspections and compartmentation.
Passive fire protection surveys and installations are particularly important for:
