1. Large glass, south-facing windows

Glass trapping heat

The windows are double-glazed with a new type of glass that is a better insulator than normal glass. The particles in the glass are further apart so heat conduction is slower. Some of the gas between the two panes of glass has been removed so less conduction happens in the gap.

Do you know about conductors and insulators?
