Hi Does anyone know of a bi-fold door which meets fire regs?

I am building a loft room and want to put the door to the stairs (to the loft room) at the bottom opening onto the landing. To do this I would need a bi-fold door to meet minimum restriction requirements on the landing.

First thing to say is to make you aware that a fire door is either a fire door or it is not when you buy it. You cannot make your own. I'm not aware of there being a bi-fold fire door on the market. The only thing I could think of is to get yourself a fire door blank from Howdens or similar and cut it down to make the two leaves to suit. Obviously fire seals will be a must, it also might be worth getting a rebate built in where the leaves close together. A fire door blank is basically a huge fire door that can be cut down to suit a particular opening.

Only written confirmation from your area Building Inspector that this solution will be Approved should be relied upon.
You can buy firedoors from howdens/magnet/jewsons...

They come in two sizes 8ft x 3ft and 8ft x 4ft.

They are pretty usefull as long as you don't mind them looking pretty plane.

I've just finished a modern house and used them - lovely weight and feel.

I've painted them with satinwood (rollered on). After each coat I use my FESTOOL sander and vac, after getting down to a 600 grit. It's like having a gloss silk finish - very nice.

I used a TREND router bit to cut the firestop rebate. However, hang the door and put all the furnature on first. I found that I still needed to paint the rebate are to make the fireseal sit tight.

The BCO has said it is ok to use bi-fold door "so long as it meets 20 min fire regulations". We plan to use Bollom Intuclear flame-retardant clear varnish on the current doors and the door to the loft, which has been approved.
