Fitting a second pane of glass to improve insulation began in Scotland, Germany, and Switzerland in the 1870s. [3] Insulating glass is an evolution from older technologies known as double-hung windows and storm windows. Traditional double-hung windows used a single pane of glass to separate the interior and exterior spaces.
The ideal gap size varies by location, but on average it ranges from 15-18 mm thick, giving a final assembly size of 23-26 mm assuming a typical glazing thickness of 4 mm. [9] A double-paned window with air in the gap has an R-value of 2.1, which is much better than the 0.9 that a single pane of glass yields. A triple-paned window, which is not ...

Clear double glazing has a U-factor between 1.8 and 3 W/(m 2 ⋅K) or between 0.3 and 0.5 Btu/(h⋅ft 2 ⋅°F) (about R-2) Clear triple glazing has a U-factor between 0.5 and 1 W/(m 2 ⋅K) or between 0.1 and 0.2 Btu/(h⋅ft 2 ⋅°F) (about R-3). Double and triple glazing are critical for energy efficiency. Single glass windows are no longer ...
The panes of glass are separated, creating an insulating air pocket that inhibits heat transfer much better than single pane windows. Double-paned windows have two parallel panes (slabs of glass) with a separation of typically about 1 cm; this space is permanently sealed and filled at the time of manufacture with dry air or other dry ...
Quadruple glazing (quadruple-pane insulating glazing) is a type of insulated glazing comprising four glass panes, commonly equipped with low emissivity coating and insulating gases in the cavities between the glass panes. Quadruple glazing is a subset of multipane (multilayer) glazing systems.
