What do these terms mean?

• Double pane window: This is an energy-efficient window which consists of two panes with a layer of gas sealed in between. (Triple pane windows are also available.)

• Single hung window: In this type of window, only the bottom sash can be moved; the top sash is stationary.

• Double hung window: Both top and bottom window sashes may be moved up or down. Double hung windows, while more convenient, are more expensive both to install and to replace.

• Frame: The window frame could be made of vinyl or wood. Wood is costlier.

• Low E: Short for “low emissivity,” this phrase refers to windows which have been specially coated to block heat transfer and harmful ultraviolet sunrays.
