[Readytolearn]

Hi, just wandering of its ever an option to install bifold doors without an rsj. Just screwed into roof joists. Is this a poor idea. Thanks

Then a thin plastic/aluminium frame and sheet glass is holding up the roof? Doesn't sound great.

With respect to the opening as above.

Assuming the bifold is floor supported (as opposed to suspended from above as some are) it may not need a beam above per se but would need adequate support/restraint due to wind loading's and keeping the whole frame rigid etc.

Do you already have an opening wide enough to fit bi-fold doors? If yes, then you need to check there is currently a lintel of some sort to hold up the structure above, even if it is just the roof beams in a bungalow.
If you don't already have an opening then you will definitely need a correctly sized lintel. Even a standard window has, (or should have), a lintel above it.

Tell us more. I'm trying to imagine a scenario where you would have an opening, doors, roof above and nothing supporting the span above the opening....

Is this a builders proposal or yours?
Please don't say you or a builder has already started/finished doing it this way!

Tried convincing me that’s the way it should be . There now looking for work somewhere else…I’ve told them to pack there stuff up…… Apparently it’s fine to screw doors up-to roof joists.

If there is a rigid timber structure or fixed structural elements above the doors, then there is nowt wrong with fixing into them.

Some images may be helpful.

Flat roof, joists parallel to the opening and the doors on bottom runners not top hung.

There’s a wooden joist above the opening , I’ve measured the height on both sides and there’s 36 mm difference from one side to the other . Seems a big gap .
