Unidentifiable flat front entrance doors

[tom115]

Hi,

We have a couple of blocks in a London borough with a fair amount of fire doors within them. The blocks were built or in early/mid 2000's. 

The doors are of a regency style and have a 2mm metal skin on them with a beech hardwood perimeter framework. There is a hole/cap on the head of the door where it is assumed the foam injection was applied. The only markings present are on the top with '09-06-05'. Id guess this a manufacturer date. 

We have had no such luck with the developer, and cannot seem to identify these door sets at all. 

Do any of you know a way/system to find some sort of manufacturers information? I've read on here possibly on/under a hinge. 

I would upload images but it keeps stating error (they are under 500kb).

From what I understand these type of fire doors were popular late 90s. We are only trying to confirm a fire rating, otherwise we are going to have to seek a very expensive burn test. 

 

Any ideas?

 

Thanks

This type of composite fire resisting door was popular in the early 2000s.  Is the self-closer a chain type, fitted to the hanging edge of the door and hanging jamb of the door frame? Many were.

Could be a Birtley or IG door but unlikely that the manuufacturer would still hold data after this length of time. You could try contacting https://www.acdm.co.uk/ The Association of Composite Door Manufacturers, if you send them images of the doors they may be able to help.

You may find Para 62.17 of the HM Gov guidance at https://assets.publishing.service.gov.uk/media/65e9def95b6524001af21bcc/Fire_Safety_in_Purpose_Built_Blocks_of_Flats_Guide-update.pdf  helpful in terms of Notional Fire Doors.
