Flush Fire Doors

What is a Flush Fire Door?

Flush doors are, as the name suggests, largely flat internal doors that are flat faced with no inset panels which are seen in stile and rail type doors They are elegant in their simplicity, giving the appearance of being made from a single piece of timber.  

Flush fire doors are made from a veneer of oak, walnut, ash or hardwood around a solid core.

It’s important that flush fire doors are installed within a fire door frame. Fire doors are thicker than most internal doors at a minimum of 44mm while most standard doors are 35mm thick. However, there is a much more important reason to use a fire door frame. Installing a fire door leaf within a fire door frame ensures a perfectly snug fit upon installation, enabling the intumescent seals in the frame to close the gap between leaf and frame when activated. Fire doors must be hung using CE-certified hinges as these will not warp or melt in extreme heat.

Internal flush doors are extremely stylish and incredibly versatile. While they lend themselves well to contemporary design concepts, they are also perfectly at home in properties with more traditional or rustic aesthetics.

Our FD30 Fire Door Range

Browse our selection of flush doors and you may notice that many of them are classified as FD30-rated. This means that they have been rigorously tested to standards established by the British Woodworking Federation, and will keep fire and smoke at bay for a minimum of 30 minutes. At 44mm in thickness, they are much more robust than standard internal doors which average around 35mm thickness.

FD60 Flush Fire Doors

FD60 flush fire doors are even thicker than their FD30-rated counterparts at 54mm. This enables them to keep fire and smoke at bay for a minimum of 60 minutes rather than 30. While 30 minutes is usually enough time to evacuate most residential properties, fire doors with an FD60 fire rating  may be more suitable for multiple occupancy buildings (such as apartment blocks) and  commercial premises.

Should Fire Doors Have Intumescent Strips?

Around the circumference of a fire door frame, you will find a rubbery-looking intumescent strip. Upon reaching temperatures of around 200 degrees Celsius, this strip will expand, preventing heat from escaping through the gap between the door and the frame. Flush fire doors may also be fitted with cold smoke seals to prevent smoke from issuing between the door leaf and frame.
