Double-paned thermal insulating windows consist of two glass panels separated by a narrow gap from which most of the air has been removed to create a near vacuum in the space between the panes. Explain how this design helps to better insulate a home than a window that is made from a single sheet of glass. a) The double-paned window allows for less heat loss through conduction. b) The vacuum between the two panes of glass acts as a very efficient insulator. c) The double-paned window allows for less heat loss through convection. d) The vacuum between the two panes of glass acts as a very efficient conductor.
