Oak Fire Doors for Standard 30 Inch Openings
At 762mm, or 30 inches, this is the standard internal door width in the UK, so it is where most fire door projects begin and where this range is at its fullest. If you are fitting fire doors to bedrooms, a living room or a hallway in a home built to modern sizing, this is almost certainly the width you need. Every door here is one of our oak fire doors in a 762mm width, an oak veneer over a dense, fire-resisting engineered core.
When a Fire Door Is Required
Fire doors are needed in a few specific places rather than throughout a home, and at the standard width you will meet nearly all of them. The common trigger is a house of three storeys, including a loft conversion that adds one, where the habitable rooms opening onto the stairway and escape route must be FD30; a door between the house and an integral garage is another. Because 30 inches is the size modern homes are built around, these openings are usually already this width, so a 762mm fire door is the straightforward upgrade. The regulations carry more detail than this, so it is worth confirming exactly what your own project needs.
The Fullest Choice of Fire Door Styles
As the most common size, 30 inches carries the fullest choice of designs, so you rarely have to compromise on the look to meet the rating. You can choose a modern flush or grooved face for a contemporary room, a panelled door for a classic hallway, or a traditional period design, and glazed faces are made at this width where a darker hall or landing needs light.
- Modern flush and grooved faces for contemporary rooms
- Panelled fire doors in four and six panel layouts
- Traditional period designs for older homes
- Glazed options where you want to borrow natural light
Core, Rating and Certification
The doors at this width are supplied by established makers including Deanta, LPD and JB Kind, and all share the same genuine build: a fire-resisting core faced with an oak veneer and edged with oak lippings. The core is what carries the certification, while the oak face gives the grain, which is why a true fire door is never solid oak. The majority are FD30, holding fire for up to 30 minutes, which suits most homes; where 60 minutes is specified, our FD60 fire doors meet that standard.
From Leaf to Fitted Doorset
A fire door reaches its rating only as a complete, fitted set, so the leaf is one part of the job. It hangs in a suitable fire door frame or lining, on the correct fire-rated hinges, with intumescent strips and smoke seals closing the gaps as a fire takes hold. On finishing, a prefinished door has its faces sealed and hangs faster, though the hinge and latch cut-outs need sealing as you fit, while an unfinished door lets you choose your own tone once every face and edge is treated, as covered in our internal door treatments guide.
762mm (30 Inch) Fire Door FAQs
