Our 35mm fire doors are designed to offer all the benefits of thicker fire doors, whilst keeping a slimline profile. Each carries an FD30 fire rating and has been rigorously tested to ensure it offers the requisite level of protection. Our 35mm fire-rated doors are available in a wide range of styles to complement our standard internal doors and ensure a consistent look throughout your home. See for yourself below.
We pride ourselves on our outstanding range of fire doors. While most are 44mm thick FD30-rated fire doors, or 54mm FD60-rated fire doors, there are slimmer options available. Although these are less commonplace, they're ideal for shared homes, compact guest properties such as bed and breakfasts, commercial buildings or any location where thicker 44mm doors can't be accommodated due to narrower frames.
Oak is one of the most versatile and beautiful timbers on the market and a firm favourite for internal doors. Our 35mm fire doors consist of a stunning oak veneer surrounding a solid core.
As well as providing outstanding fire protection, the solid construction also offers great sound and thermal insulation, making your home more comfortable while protecting your household in the event of a fire.
White prime+ doors offer a pristine and highly versatile effect that looks beautiful in any home. These doors have a top coat that acts as a final coat or a primer, giving you the option to hang them straight away. They can also be painted over in white or any colour of your choice, thanks to the smooth finish.
These doors look just as good as a traditional, standard option but they also help to stop the spread of flames and heat in the event of a fire. They fit into a standard frame, so you'd never know they offer fire protection.
When you choose one of these durable, attractive and safe 35mm FD30 rated doors, you can modernise and protect your home. Their MGO (magnesium oxide) sandwich board core is hidden inside an outer casing that doesn't give away their capabilities.
They're low maintenance, come at an affordable price and easy to install. Always work with a professional and follow fitting instructions to ensure these are fitted in accordance with fire regulations. Choose fire rated frames and hinges to complete the installation.

Frequently Asked Questions
Yes, absolutely! Most fire doors are 44mm in thickness, which may give shoppers pause when they see a 35mm fire door. However, a 35mm fire door (also known as a slimline fire door) may still be FD30-rated. This means that it meets the rigorous testing standards of the British Woodworking Federation, and can withstand fire and smoke for a minimum of 30 minutes. In most domestic settings, this is ample time to evacuate the property and alert the emergency services.
In other words, 35mm slimline fire doors are just as safe and effective as their 44mm counterparts. Plus, they can be installed in a standard-sized fire door frame. 44mm fire doors, on the other hand, need to be installed in a 44mm fire door frame in order to provide a flush fit between the door and the frame or the door set would not be compliant with Building Regulations.
While 35mm fire doors may be slimmer than their conventional counterparts, they may still be compliant with Building Regulations as long as they are properly installed by a registered professional. Looking carefully at a 35mm fire door and its hardware will help you to identify whether a fire door is compliant.
Open the door and you should find a rubbery intumescent strip running around the door frame. This expands when ambient temperatures exceed 200 degrees Celsius, preventing heat from leaking between the door leaf and frame in the event of a fire. It may also have a cold smoke seal which is raised slightly and has a fuzzy texture. This prevents smoke from seeping through the gap between the leaf and frame.
This gap should be 3mm in width to ensure that the fire door is effective and compliant. The gap can be no more than 4mm and no less than 2mm.
Please note that slimline fire doors must be installed in a fire door frame. They cannot be installed in a standard door frame, which does not have sufficient density to withstand a fire. They also cannot be installed with regular hinges, which may melt, warp or buckle in the event of a fire. They must be outfitted with CE-registered fire door hinges.
Always follow fitting instructions, and if in doubt, enlist the help of a professional.
