There's this one too https://www.lorientuk.com/products/batwing

The lipping should be hardwood at least 640 kg/m3, at least 6mm retained thickness (after planing-in) and must not be in addition to existing lipping. Adhesive should be urea formaldehyde. Use a carpenter that has sufficient knowledge about timber-based fire door installation, maintenance and repairs.

There are two options here, the problem being that many timber-based fire doors have an integral top rail that should not be over-trimmed: 1) Always replace existing door frames rather than fitting a new door leaf only. This is most often necessary to achieve compliant installation. 2) If you must retain the existing door frame, then the door leaf must be custom made to suit the door frame. Furthermore, if you must retain the existing door frame ensure the following: A) The framing material is in good condition and of suitable dimensions and density. B) The existing

Seals should be fitted to the main leaf only so as not to be interrupted by flush bolts at the top and bottom edge of the secondary leaf. Where there is no bolt the seals may be fitted to the meeting edges of both leaves but offset, not opposing.

Can the door leaves be trimmed to suit the frames?

The Standard 'BS 8214 Timber-based fire doors assemblies - Code of practice' states that a typical gap to achieve good fire performance is 2mm to 4mm. A code of practice provides guidance and recommendations and should be applied by those that install and maintain timber based fire doors. Whether the gaps have become "larger than they should be due to natural shrinkage" might be the subject of a debate. Might they have been "larger than they should be" at the time of installation, five years ago? Clearly, work to make the gaps compliant to the Standard would improve the likely

Your friend could contact an independent fire door inspector at https://fdis.co.uk/find-an-inspector-2/ or at https://www.blueskycert.com/members-main/ but that would not guarantee that the door would be compliant, only that a competent inspector would advise on the suitability of the existing door.

This is one for a competent architectural ironmonger.

Most standard fire doors cannot be trimmed by such an amount and quite often the top edge may not be trimmed at all. Contact a reputable fire door supplier and ask them for a suitable fire door.

Some chain closers do conform to BS EN1154 and have controls for adjusting the closing speed and the latching action. The self-closing device in the picture looks similar to the Perkomatic by Samuel Heath. Look for a manufacturers mark on the self-closing device and contact them for the adjustment instructions.

In my experience FD60 require 20mm minimum (in one or two strips). Are you sure they are FD60? Sometimes 54mm thick doors are used for other reasons than their fire resistance properties.

For FD30(s) timber-based fire doors the intumescent seal size is usually 4mm thick x 10mm or 15mm wide so and the seal should fit tightly in the groove and flush with the edge of the door leaf. The integral brush or blade should only lightly contact the opposing surface, ie. the one that it sweeps or compresses against. So if the groove is too deep, it would be necessary to cut a fillet from thin hardwood or MDF to fit tightly into the groove behind the intumescent seal. Ensure that the fillet is continuous and that there are no voids behind the seal.

Hi Paul, Fire Door Inspection Scheme Transition Module. Should I come across this elsewhere, I will post here.
