Timber Fire Doors - A Handbook for Professionals

[redbadge]

This is referred to in Annex C of BS ISO/TR 12470, but try as I might I can't find any reference to it other than within that standard.

Anyone able to help in locating a source for a copy?

With difficulty - why do you want to do it. There are some excelent fire doors on the market in most architectural styles. Buying new doors often works out cheeper and is certainly better than messing about trying to upgrade them.

Take a look at the envirograf products - they may be of use if your doors are worth saving. What have you got- are they panel doors or flush, what timber, how thick are the stiles and rails? are they a good fit in the frame and free from warp or damage?

If they are flush hollow doors with cardboard eggbox contsruction then they cannot be upgraded

There are some good publications around- such as the BM Trada "fire door sets by upgrading" and the ASDMA guide to fire doors available for free download. Many local authority websites covering Houses in Multiple occupation also have info on upgrading doors.

If your building and its doors are of some age, ie a heritage building, then English Heritage have a booklet on 'Timber panelled doors and fire' which is about upgrading timber doors and frames.
The copy I have was published in 1997 - product code XH20054.

May sound like an odd question but why do you need or want to upgrade the door?

[Galeon]

I have been on quite a few older sites after 'works' have been completed to doors , and it was found that the doors before the work were actioned were in fact better than after the butchering. Depending on the age of the door and original construction you will find sometimes less is more.

As a general rule - dont upgrade unless you really have too.
