One key difference between single- and double-hung windows is their number of operable sashes: single-hungs feature only one, while double-hungs come equipped with two. This makes cleaning your bottom operable sash from the inside much more straightforward, while for the top fixed sash, you must go outside.

Single-hung windows differ from their double-hung counterparts by having only one operable sash that moves up and down within their frame, providing ventilation through only one lower sash. This makes them less energy efficient but still suitable for many applications.

Installing your window sash correctly requires making sure the sash fits into its frame correctly; otherwise, it could fail to close properly and operate efficiently. In addition, weights and cords must be removed from both sides of the sash before opening it and installing its replacement – this ensures cold air doesn’t enter during wintertime! Furthermore, ensure all window seals are tight so as to protect against cold drafts entering through windows.
