[2] 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 ...
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 ...
