Hi I have two large old wooden 7 facet bay windows to replace - with uPVC.
This is my first bay install, more complicated than it seems.
The upstairs window has a tiled gable on top - with brick under its eaves, so assume a load is being carried, and the ground floor window supporting this weight + a rendered wall above.
I will be using Bay Window Jacks, (am unsure whether to use 1.8 or 2.74 Ali. tube at this stage, guess its doesn't hurt to over spec.)
Read this thread which was quite helpful:
//www.diynot.com/diy/threads/bay-window-problems-advice-needed.328717/
I read that proper supports 'would probably consist of a steel angle supported on corner tubes, and tied back to the main wall of the house each side of the bay.' would this be a one piece steel angle, cant see how you'd thread a 3mt peice through with Acro's in place ?
Would I be right in thinking that the ceiling joists in the roof rest directly on the top of the existing upstairs wooden frame, and same for the ground floors ceiling joists.
Once the old frame is removed - there will be no direct support for these joists, would additional noggins/blocking between existing joists, acting as a sort of trimmer between the joists be man enough to carry the weight from the joist to the bays jacks - which in some places would sit mid span on the noggin ? are they suggesting steel angle placed - under noggins ??
