Composite Fire Doors

What are they and do I need one?

Our composite fire doors have been rigorously tested and independently certified against fire for a specific period of time; the FD30 door can withstand fire for 30 minutes

Fire doors help to control the spread of fire and smoke, allowing the building’s occupants vital time to evacuate safely.

Did you know?

It is a legal requirement for residential apartment blocks to have an FD30 door fitted.

It is also an essential consideration for integral garages and homes, to provide added fire protection and peace of mind.

A composite fire door is visually very similar to a standard composite door but with the addition of fireproof materials.

  • High performance
  • Unparalleled security
  • Weather performance
  • Range of colours and styles
  • Consistency and reliability
  • Independently tested
  • Fully certified
  • Fully compliant

Benefits of a fire door

Our peformance fire doors create a highly efficient system that not only demonstrates integrity against fire, but also delivers performance relative to smoke control, security, weather, sound insulation and thermal performance. 

Plus the wide range of styles and colours available means you don’t have to compromise on aesthetics, or the overall appearance of your house, flat or office.

Composite fire doors are composed of 100 percent non-toxic materials. So even if they do burn, they will not release toxic gases.

Rigorously Tested and Independently Certified FD30 Composite Fire Doors

For Flats, Apartments, Garages and Homes

And just like a regular composite door, you can choose your style, colour, glass design and door furniture, to fully customise your new door.

Please contact our office for further information and specification details or call us on (020) 8868 1133.

Safety, security and fire protection all in one

Our FD30 composite fire doors have been fire tested on both the internal and external sides for up to 30 minutes with fully independent third party certification.

All FD30 fire doors have been tested to BS476 Part 22, and are subject to the Q-Mark enhanced security scheme. 

In addition, the doors have also been tested to BS EN 1634-3 smoke control test and comply with PAS 24 security accreditations.

FIRE DOOR FAQ

What is a fire door?

A fire door is a specially constructed door designed to resist the spread of fire and smoke between different areas of a building. Unlike standard doors, fire doors contain fire-resistant materials that can withstand flames and high temperatures for a certified period. When properly installed with the correct frame, seals, and hardware, fire doors provide occupants with valuable time to evacuate safely during a fire.

FD30 indicates that the fire door has been independently tested and certified to withstand fire for a minimum of 30 minutes. The ‘FD’ stands for ‘Fire Door’ and the ’30’ represents the fire resistance time in minutes. This rating means the door will maintain its structural integrity and prevent the passage of flames for at least half an hour, giving building occupants time to escape and emergency services time to respond.

In the UK, fire doors are a legal requirement in certain situations. You need a fire door if you have an integral garage (attached to your home), a loft conversion with a new staircase, or if your property is a flat or apartment in a multi-storey building. Building regulations also require fire doors between a kitchen and stairway in three-storey homes. If you’re unsure whether your property requires fire doors, we recommend checking with your local building control office.

Fire doors work through a combination of fire-resistant materials and specialist components. The door leaf contains materials such as vermiculite, mineral wool, or fire-resistant particleboard that resist combustion. Intumescent strips fitted around the door edges expand when exposed to heat, sealing the gaps between the door and frame. Cold smoke seals block smoke at lower temperatures. Together, these elements create a barrier that contains fire and smoke within a specific area.

Composite fire doors are made from multiple layers of fire-resistant materials. The core typically contains high-density mineral boards, intumescent compounds, and fire-retardant particleboard. The outer skin is usually a durable GRP (glass-reinforced plastic) or hardwood veneer that provides both aesthetic appeal and additional protection. All materials used are 100% non-toxic, meaning they will not release harmful gases if exposed to fire.

Fire doors should be inspected at least every six months in residential properties and more frequently in commercial buildings. Regular checks should look for damage to the door leaf, frame, and seals, proper operation of hinges and closers, and correct gaps around the door. Building managers and landlords have a legal responsibility to maintain fire doors in good working condition and keep records of inspections.

The maximum gap allowed under a fire door is 8mm when measured to a finished floor or 10mm to a threshold. Around the sides and top of the door, gaps should be no more than 4mm when the door is closed. If gaps exceed these measurements, the door’s fire rating may be compromised. Intumescent strips help seal these gaps when exposed to heat, but the specified tolerances must be maintained for the door to perform correctly.

A fire door requires a minimum of three hinges to support its weight and maintain its fire rating. These hinges must be CE marked and fire-rated (graded 13 as a minimum). Fire doors are heavier than standard doors due to their fire-resistant core, so using the correct number of properly rated hinges is essential. The hinges should be positioned with the top hinge 150mm from the top and evenly spaced down the door.

A composite fire door is a fire-resistant door constructed from multiple materials bonded together to provide superior strength, insulation, and fire protection. Unlike solid timber fire doors, composite fire doors feature a fire-resistant core wrapped in an outer skin of GRP or similar material. They offer excellent security, weather resistance, and thermal performance alongside their fire rating, making them ideal for external applications such as flat entrance doors.

Responsibility for fire doors in flats depends on the door’s location. The building owner, landlord, or management company is responsible for fire doors in communal areas such as corridors and stairwells. Individual flat entrance doors (the door leading from your flat to the communal area) are the responsibility of the flat owner or leaseholder. Following the Fire Safety (England) Regulations 2022, building owners must conduct quarterly checks on fire doors in communal areas.

In the UK, fire doors are required in several locations: entrance doors to individual flats in blocks of flats, doors leading from integral garages into the home, doors separating staircases in properties of three or more storeys, doors to kitchens in three-storey properties, and any door forming part of a protected escape route. Commercial premises, schools, hospitals, and care homes have additional requirements based on fire risk assessments.

FD30 denotes a fire door with 30 minutes of fire resistance only, while FD30s indicates 30 minutes of fire resistance plus smoke control. The ‘s’ suffix means the door includes additional cold smoke seals that prevent smoke leakage before the fire reaches high temperatures. FD30s doors are typically required where smoke control is specified in building regulations, such as in flats and along escape routes.

Only fire-rated glass with the appropriate certification can be used in fire doors. The glass must be tested and certified as part of the complete door assembly, not just as a standalone product. Georgian wired glass was traditionally used but has largely been replaced by clearer, more attractive options such as Pyroguard or Pilkington Pyrodur. The size and position of glazed panels affect the door’s fire rating, so always specify fire-rated glazing that matches your door’s certification.

I’m so glad I found Ruislip Windows and would recommend them to anyone. Honest company, great workmanship, and exceptional aftercare. Any small issues were fixed immediately with no questions asked (they replaced a scratched internal pane and buffed a mark on the frame straight away). Friendly, helpful, and reliable in a market where trust matters. Couldn’t recommend them more.

I am delighted with the installation of the new double glazed bay windows in my home. The windows are very smart and the team who did the installation were excellent. The price was good (in the middle of 3 quotes I had) and the work carried out neatly and cleanly. I have the minimum of touching up to do in one room. I am very pleased and would heartily recommend Ruislip Windows & Doorsl

Overall really impressed with the service and wouldn’t hesitate to recommend to others. Thank you!

We contacted Ruislip Windows about replacing our porch and was pleased to find they could fit new front, side panels and trim and use the original roof and frame. The whole process from Mark visiting to discuss what needed doing to Rob and Ryan fitting the new parts was excellent, all old parts were removed same day and everything was kept clean and tidy. Rob's eye for the finishing details was second to none.
We have used Ruislip Windows before and would recommend them to anyone that asked.
Thank you to everyone we spoke to, we are well pleased with the final item.

The surveyor was very helpful when he came to measure up and advised us on the types of installations available and when we could expect the installation of our doors and windows.
We received a text, within the period advised by the surveyor, asking us when would be a convenient time for the installation.
On the day of the installation the first fitter arrived early in the morning and started removing the old windows and doors. Soon after a second van arrived with the replacement doors and windows and installation commenced. The men worked non stop and completed mid-afternoon. The surrounds of doors and windows were repaired where necessary. The old fittings were removed and all the rubbish swept up and cleared away.
We were shown how the locks and the internal blinds worked.
Overall we are very satisfied with the new doors and windows and the workmanship of the fitters. We would certainly recommend Ruislip Windows and Doors Ltd to anyone.
