Therefore, the term double-paned windows essentially means the same thing as double glazed. Windows that are double glazed often feature what people in the industry describe as thermal glass, or insulated glass. There are many advantages to having this type of system in your double hung windows.

How can you tell if a window is single or double pane?

Method 1: Look at the inside edge of the window. If you see two panes of glass separated by a small spacer system, then it’s a double glazed window. If you see one pane of glass and no spacing system, then it’s single glazed. Method 2: Open the window and use your fingers to touch both sides of it in the same spot.
