Straight answers
Buying bay and bow windows
What makes a window custom?
The frame is built to the approved width and height with a selected operation, frame depth, glass package, finish, grid pattern and installation method. Manufacturing limits still apply to every combination.
What is the difference between a bay and a bow window?
A bay commonly uses three units with angled flankers. A bow uses four or more units to create a gentler curve.
