Fireproof doors play a critical role in passive fire protection by helping to slow the spread of fire and smoke through a building. By containing fire to a specific area, they help reduce structural damage and give people time to evacuate safely. In the UK, fire rated doors are a legal and practical requirement in many building types, supporting compliance with national fire safety regulations.
For buyers, the most important point is that a fireproof door should be selected as a complete doorset, not only as a leaf. The frame, hinges, closer, seals, glazing, locks, handles, and installation detail all contribute to the final fire performance. A certified door loses much of its value when it is fitted with unsuitable hardware or when gaps around the frame are not controlled.
In residential buildings with multiple occupants — such as flats, apartments, or dormitories — internal fire doors are typically placed in corridors, stairwells, and between living areas to create safe escape routes. The Fire Safety Regulations 2022 require regular inspections of fire doors in buildings over 11 metres tall to ensure they are functioning properly.
In commercial buildings like offices, shops, and hotels, fire rated doors are used to separate higher-risk areas (such as kitchens, plant rooms, and storage areas) from public or staff zones. These doors must comply with standards such as BS 476 and EN 1634, which test their resistance to fire and smoke over time.
Fire Rated Doors Ratings
UK fireproof doors are classified by how long they can resist fire — most commonly FD30, FD60, FD90, or FD120 — indicating resistance for 30, 60, 90, or 120 minutes. These ratings refer to the door’s ability to remain structurally sound and limit the transfer of heat during a fire.
In practical terms, FD30 doors are commonly used where the goal is to protect standard escape routes and internal compartments, while FD60, FD90, and FD120 doors are selected for higher-risk zones, longer evacuation routes, plant areas, service rooms, industrial spaces, or buildings where the fire strategy requires extended protection. The correct rating is normally confirmed through the project specification, fire risk assessment, or building control requirements.
Fireproof Doors - Built for Protection and Performance
At FireResist, we manufacture modern fireproof doors using advanced materials and certified methods. Whether you need solid core doors or fire rated options with glazed panels, our solutions are designed to combine safety with style. Fire-resistant door glazing allows natural light into a space without compromising on protection.
Door choice also depends on daily use. A frequently used corridor door needs reliable closers, robust hinges, impact-resistant surfaces, and hardware that remains comfortable for staff, residents, or visitors. In access-controlled areas, the fire rated door must work with compatible locking systems while still allowing safe escape in an emergency. For glazed fire doors, the glass size, position, and framing system are chosen to balance visibility, light, privacy, and certified fire resistance.
Our doors are built with:
-
Steel – Strong, durable, and non-combustible, steel fire doors are ideal for high-risk or industrial areas.
-
Fire-resistant glass doors – Designed for light and visibility, our glazed fire doors feature specially treated glass that expands when exposed to heat, helping to insulate and block smoke and flames.
Each project can be adapted by size, configuration, finish, and performance requirement. Made-to-measure fireproof doors are especially important in refurbishment work, heritage properties, plant rooms, service corridors, and commercial fit-outs where existing openings rarely match standard dimensions. Custom manufacturing helps achieve a cleaner fit, reduces awkward site adjustments, and supports a consistent finish across the building.
All of our fireproof doors are tested to meet or exceed UK fire safety standards, including BS EN 1634-1 and BS 476-22. They also comply with the Fire Safety Order 2005 and the Fire Safety Act 2021. With fire resistance ratings from FD30 to FD120 and ISO-certified manufacturing, our doors deliver dependable protection for residential, commercial, and industrial settings.
Fire Rated Doors Are More Than Just For Compliance
Neglecting proper fireproof door installation or maintenance can lead to devastating outcomes. In several past UK fire incidents, malfunctioning or poorly fitted doors were linked to rapid fire and smoke spread. A well-installed, certified fire rated door is not just a box to tick — it is often the deciding factor between containment and catastrophe.
Building owners, landlords, and facilities managers are legally responsible for ensuring all fire doors — particularly those in escape routes or communal areas — are kept in good working order. This includes routine checks of door closers, intumescent seals, glazing, and signage. Even minor damage or misalignment can compromise fire door performance during an emergency.
Fireproof Doors - Designed to Work With Your Interior
Fireproof doors no longer mean industrial-looking barriers. At FireResist, we offer a range of aesthetic options — from timber finishes to minimalist steel or glazed designs. Whether you’re working on a residential, commercial, or heritage project, our doors can be customised to match interior themes while meeting all safety standards.
The finish should be chosen with both design and maintenance in mind. Steel doors suit demanding environments because they resist knocks, frequent handling, and heavier-duty use. Timber-effect or painted finishes integrate more naturally into offices, apartments, hotels, schools, and public interiors. Glazed options make enclosed routes feel lighter and easier to navigate, while solid doors provide stronger visual separation where privacy is important.
