The thickness of a double-pane window depends on the style of window and if there are any insulating features. There are many different window styles available depending on what look you’re trying to create for your house. For instance, standard double-hung windows usually have a slim frame and sash, while larger styles, such as bay and bow windows, have a slightly thicker frame to support the extra glass.
Most energy efficient windows, no matter which style they come in, will have a thicker build to account for insulating features. The frames are bigger because they include a series of small chambers that act as buffers to prevent heat loss. Plus, there may be other features, such as weather stripping, locking mechanisms, and hidden screen tracks built into the frame that would increase its size.
Then there is the glass itself. Because insulation is the goal, glass in energy efficient windows may be thicker than what you’d find in a regular window. There are two sheets of glass in a double-pane design, usually with a gas-filled spacer between. So, with these insulating features, you can expect that an energy efficient double-pane window will be slightly thicker than a non-insulated counterpart.
