Here is the senario:
1. Bow window; fiberglass, 126" long x 66' high, 5-section of which 3 are pictures (ends and center) and 2 are casements.
2. Wall is an END wall of a room with a cathedral ceiling. Lannon stone is on the exterior below the window. I don't know the interior structure of the wall.
3. Installer said the window will be attached via the two side jams as well as the bottom jam and...
4. Supporting the cantilevered bow will be cables (they don't do chains) attached to the studs of the wall above the window and...
5. NO knee braces will be used.
A different remodeler said the wall/ceiling arrangement of a cathedral is not designed to support the cantilevered bow and thus it would flex and the bow would sage and the casement panes would then jam. I have also heard that the CABLING tends to stretch, requiring additional adjustment in the future. I have been told a chain supporting system will not stretch!
