Fire Door Manufacture, Installation, and Maintenance: Protecting Lives and Property
Written by FSG Ltd, 15th May 2025 - 5 min read

❝ When it comes to fire safety in any commercial or corporate building, there are many layers of protection, from active sprinkler systems to alarms that alert occupants. However, one of the most critical, yet often overlooked, components of a robust fire safety strategy is the fire door.
At Facility Servicing Group, we understand that fire doors are not just ordinary doors; they are vital barriers, meticulously designed to prevent the spread of fire and smoke, providing crucial time for occupants to evacuate safely and for emergency services to respond..
More Than Just a Door: The Role of Fire Doors
More Than Just a Door: The Role of Fire Doors
A fire door is an integral part of a building's passive fire protection system. Unlike standard doors, fire doors are specifically constructed with fire-resistant materials and components, tested to withstand fire for a specified period (e.g., 30, 60, or 120 minutes). Their primary function is to:
- Contain Fire: Slow down or completely prevent the passage of flames from one fire compartment to another.
- Prevent Smoke Spread: Crucially, they also limit the spread of toxic smoke, which is often the leading cause of fatalities in a fire.
- Protect Escape Routes: Ensure that corridors, stairwells, and other escape routes remain clear and safe for occupants to exit the building.
- Limit Property Damage: By containing the fire, they significantly reduce the overall damage to the building structure and its contents.
The Lifecycle of a Fire Door: Manufacture, Installation, and Maintenance
The Lifecycle of a Fire Door: Manufacture, Installation, and Maintenance
For a fire door to perform its life-saving function effectively, it must be correct at every stage of its lifecycle: from initial manufacture to professional installation and ongoing, meticulous maintenance.
1. Fire Door Manufacture: Built for Resilience
The journey of a reliable fire door begins with its manufacture. This is a highly specialised process, adhering to stringent British and European standards (such as BS 476 Part 22 or EN 1634-1). Key aspects of fire door manufacturing include:
- Core Material: Using fire-resistant core materials like particleboard, flaxboard, or solid timber, often treated with intumescent compounds.
- Components: Every element, from the frame and glazing to the hinges, seals, and ironmongery (handles, locks, closers), must be fire-rated and tested as a complete unit.
- Intumescent Seals: These are crucial strips fitted into the door frame or edge. When exposed to heat, they expand rapidly, sealing the gap between the door and the frame to prevent the passage of smoke and hot gases.
- Smoke Seals: Often combined with intumescent seals, these brush or fin seals prevent the passage of cold smoke before the intumescent material activates.
Choosing fire doors from reputable manufacturers who provide proper certification (e.g., BWF Certifire) is paramount.
2. Fire Door Installation: Precision is Paramount
Even the highest quality fire door will fail if not installed correctly. Fire door installation is a specialist skill that must be carried out by trained and competent individuals. Common installation flaws that compromise a fire door's integrity include:
- Incorrect Gaps: Gaps that are too wide around the door leaf will allow fire and smoke to bypass the door.
- Improper Frame Installation: If the frame is not correctly aligned, securely fixed, or made from a fire-rated material, it will not withstand fire.
- Unsuitable Ironmongery: Using non-fire-rated hinges or closers means they can melt or fail, preventing the door from closing properly or staying shut.
- Missing or Damaged Seals: Without intact intumescent and smoke seals, the door's ability to contain fire and smoke is severely compromised.
- Modifications: Any unauthorised modifications, such as adding cat flaps or vents, will void the fire rating.
Proper installation ensures the entire "fire door set" (door, frame, hardware, and seals) acts as a unified fire barrier.
3. Fire Door Maintenance: The Ongoing Guardian
Once installed, a fire door's effectiveness relies heavily on regular and competent maintenance. Fire doors are subject to daily wear and tear, and even minor damage can compromise their integrity. The Regulatory Reform (Fire Safety) Order 2005 places a legal responsibility on the "responsible person" to ensure fire doors are properly maintained.
Key maintenance checks include:
- Door Closers: Ensure they close the door fully and effectively from any angle.
- Hinges: Check for looseness, damage, or missing screws that could affect alignment.
- Gaps: Verify the gaps around the door are consistent and within tolerance.
- Seals: Inspect intumescent and smoke seals for any damage, swelling, or missing sections.
- Glazing: Check fire-rated glass for cracks or damage and ensure it's securely fixed.
- Damage: Look for any physical damage to the door leaf or frame that could compromise its fire rating.
- Signage: Ensure all fire door signage (e.g., "Fire Door Keep Shut") is clear and legible.
Regular inspections (e.g., quarterly or annually, depending on usage) and prompt repairs are essential to ensure fire doors remain fit for purpose throughout their lifespan.
