Bi-Fold Doors - hanging on hinges?
Ever used bi-fold interior doors?
I'm in the process of planning the next room to do up, the downstairs loo. It's kinda small, and I want to box in the pipes and fit a concealed cistern, and tile floor and walls to match. All to try and make it feel bigger and more modern. But this means moving the tiny sink further towards the (opening- inwards) door and it will clash. I've thought of hinging the door the other side, but that will not give a very wide opening to get into the toilet. I also thought of hinging the door top open outwards into the hall, but there is a safety aspect there, with two small kiddies running around. So I had the idea of replacing the standard 30" door with a bi-fold internal type as sold by Wickes/B&Q/Magnet etc We've got some of these on our airing cupboard and they work OK, and slide in a top rail, with a floor mount pivot. Do they always mount like this? Or can I simply hang the pair of doors on 3 standard hinges, in a standard door frame? I am only talking basic white primed hollow door, not a heavyweight solid type. Have you ever seen this done? Does it work? Painters10 |

Why have you posted this twice? Daft question google fecking groups... I wondered that as well :-) Do they always mount like this? Or can I simply hang the pair of doors on 3 standard hinges, in a standard door frame? I think you will find there is a very good reason they do all mount like that..... I think you'll run into problems unless the door frame is *exactly* plumb (left to right and front to back) and square. You can probably set fixed hinges such that the door is fine closed *or* open but not both, bi-fold doors are weird things when you open/close 'em. Exactly. Chances of getting two sets of opposite acting hinges to work properly is remote. Fiddling about moving ordinary hinges a mm in/out of the jamb or a mm further away or in is not simple. Doing it with the adjustable top and bottom pivots and a plumb line is *much* easier. Indeed. The top & bottom pivots are the key to them working properly. There isnt anything on the floor except in the corner under the door. Two points. You can't really trim bi-fold doors to fit the opening. The opening has to be adjusted to fit the door. Second, watch out for the bottom pivot. Its a threaded metal thingy that is screwed into a threaded plastic insert in the door. Very easy to strip the thread in the plastic insert. The last two sets I fitted were from Homebase & seemed much better because the plastic insert was bigger. -- Dave - The Medway Handyman www.medwayhandyman.co.uk |

Sorry about the double post, one was meant as an email! Doh!
Thanks for the responses. I will measure how square the frame is, and decide whether to risk it based on that. Painters10 |

In addition to confirming the opening is plumb and square you can
apply a further risk reduction measure. Use a router (with depth stop set) and a hinge jig to ensure all the hinge leaf recesses are alike. That way the door leaf furthest from the hinged jam should lie truely parallel to it. Good luck. |

On Apr 18, 9:05*pm, "The Medway Handyman" * Exactly. *Chances of
getting two sets of opposite acting hinges to work properly is remote. In what way? * Fiddling about moving ordinary hinges a mm in/out of the jamb or a mm * further away or in is not simple.

I managed it, at least to the same extent as you would trim any door. *The opening has to be adjusted to fit the door. No it doesn't. I fitted two sets of bifolds on hinges across an opening with flush bolts to hold the various leaves closed when not open. It wasn't that hard and they work just fine. I agree with the other poster to use a router for the hinge recesses. My only regret is not using parliament hinges so that they would fold back further against the wall, but that's a job for another day. Andrew |
