How is a double-hung window different from single-hung?Both the upper and lower sashes move vertically in a double-hung window. In a single-hung window, the upper sash remains fixed and only the lower sash moves. What should I check about reach and locking?Check that the intended users can reach the locks and operate the sashes from the finished room layout.
