Straight answers

Buying specialty-shape 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.

Is width and height enough for an arch?

Usually not. The spring line, rise, radius or template may be needed to reproduce the opening accurately.
