Bay Windows in Central New York | New York Sash

Planning Your Bay Windows Project

Bay replacement requires more than ordering three pieces of glass. The projection, support, head and seat boards, exterior weather protection, and interior trim must work together. New York Sash measures the complete assembly and plans how an existing bay will be removed and finished so the new unit is supported and sealed.

Bay Windows Frequently Asked Questions

Q: How is a bay window different from a bow window? A: A bay normally has three sections set at defined angles. A bow uses four or more sections to form a gentler curve. Q: Do the side windows in a bay open? A: They can. Depending on the design, the flankers may be casement or double-hung units while the center remains fixed. Q: Can an existing flat window become a bay window? A: Sometimes, but support, structure, exterior projection, and local requirements must be evaluated on site before that scope is promised. Q: How is the projection protected from weather? A: The top and bottom of the assembly need insulated, flashed, and finished protection suited to the opening. Exact details depend on the house and existing construction. Q: Can the interior ledge be used as a seat? A: Only when the assembly is specifically designed and supported for that use. A consultation can distinguish a display shelf from a load-bearing window seat.
