Straight answers

Buying single-hung 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 single- and double-hung?

A single-hung window opens from the lower sash only. A double-hung window has two operable sashes.
