Fire Doors

Our Fire-Rated Door Range

All of our fire doors undergo rigorous testing, are fully accredited, and are available as single doors. We offer two types, depending on your needs and budget:

1. Our FD30 doors are 44-45mm thick and come in glass, panelled or flush designs.

2. Built for higher protection, our one-hour fire-rated FD60 doors are 54mm thick. 

FD60 doors, most commonly used in commercial settings, are usually more expensive due to the restricted choice and the required construction and installation methods.

Gain peace of mind knowing your home meets fire safety standards without compromising on style.

• The images are for a visual appreciation of what is possible, with double fire doors shown only as a visual indication of how they might look in a real setting.

• There mustn’t be any rebating carried out on these doors where they meet in the middle, as this will result in failure to comply. 

• Double-check the full requirements for all associated fittings to meet with any necessary approvals. This high-quality collection of fire doors online is unrivalled in the UK.

Durable Materials

We only use the highest-quality materials for our doors. Our fire door frames meet all required UK standards for strength and safety. This includes correct section sizes and fire-rated construction. 

We use fire-rated core materials built for durability. Many are timber-framed with a tough veneer, and some include 5–20mm hardwood lipping for added edge protection.

The veneer you choose affects both appearance and durability, with a range of premium finishes available.

• Oak Veneer: Crafted with a solid core and finished in real oak veneer, these doors combine lasting strength with the warm, natural look of genuine oak grain.

• Plywood: The unfinished and paint‑ready plywood fire doors we offer provide a practical, customisable surface ideal for bespoke finishes.

• Walnut: Featuring a high-quality walnut veneer in a range of cuts and tones, these doors bring rich character and a premium finish while maintaining fire-rating compliance.

Match your colour choice with the perfect finish for your style, fire door installation timeline and maintenance needs.

• Prefinished: Ready to install with a certified, smooth finish that saves time and looks flawless from day one.

• Unfinished: Perfect for full customisation if you want to paint or stain your door on-site to match your décor.

• Laminated: These durable, easy-to-clean finishes withstand high traffic while preserving fire-rating compliance.

Fire Door FAQ’s

What is the difference between a fire door and a standard internal door?

Fire-rated doors are designed specifically to prevent the spread of fire and smoke, providing vital time for evacuation. 

They are constructed with fire-resistant materials and include features like smoke seals that expand when exposed to heat, sealing gaps to block smoke and flames. Standard internal doors lack these protective elements and are not tested or certified to be a fire-resistant door.

Do residential fire doors need to be certified?

Yes. Residential fire doors should be certified to ensure they perform as intended. While not always a legal requirement, third-party certification provides assurance that the door meets fire resistance standards.

This is especially important for flats, communal areas, houses in multiple occupation (HMOs) or loft conversions, where fire safety is critical. Always check for certification labels and ensure the entire door set—including the frame and hardware—complies with fire safety demands.

How do fire doors self-close?

Internal fire doors self-close using a spring or hydraulic closer, or an electromagnetic holder linked to the fire alarm. These devices ensure the door shuts and latches automatically to stop the spread of flames and smoke in the event of a fire.
