Abstract
Improved thermal insulation between the inside of a building and the outside environment is provided by a multiple-glazed window comprising two transparent glass sheets, an exterior sheet and an interior sheet, spaced from each other and joined about their edges to form a sealed, enclosed space between them as the exterior sheet is a heat-absorbing glass having an infrared reflecting, transparent film of tin oxide disposed on its surface which faces the interior glass sheet in the window.
