Straight answers

Buying basement 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.

Are all basement windows egress windows?

No. Egress depends on clear opening, sill height, window-well dimensions and local requirements—not the room location alone.
