Hi,
I have previous experience of fitting straight uPVC windows, and am now to replace some old timber Bay windows, they are quite large: 7 segment, total width 3mt, projection 1.2mt.
I lack surveying experience when it comes to Bays though.
I am aware the old windows provide structural support, I am being offered windows with a 38mm 1.8mm aluminium pole (6x poles in total), the on-line windows supplier does not sell the thicker 2.7mm pole, I have asked why no thicker poles available, but they will not commit to any questions I have, or look at an image of my property - they state they 'are not fitters' !
Here is an image of the window to be replaced, it has a tiled (large format tiles) gabled roof, with brick and rendered gable wall on the first floor above, and then a rendered brick wall above ground floor - so I would have thought quite a bit of weight.
I have a 'load bearing' chart for the tube, which shows an approx 1 tonne capacity at 1.4mt height for each 1.8mm thick pole for the top floor, and 0.75 tonne at 1.8mt height for the ground floor, so as long as I can spread the load at the head of the window - then 6 tonne capacity for each set of windows will be provided.
Do I take it from the manufacturer (who supplied the load capacity chart - attached) that the 1.8mm and 2.8mm poles are a 'fits all' for 1930's semi's.
On a side issue, The window supplier has not made provision for Pole Jacks or spreader plates, so not sure how they expect you to get the poles in place - am I missing something here, do you simply shim out, wedging top and bottom then lower acros ... jacks just seem an easier way of working.
