2. Window insulation - Wikipedia

   en.wikipedia.org/wiki/Window_insulation

   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 ...

3. Insulated glazing - Wikipedia

   en.wikipedia.org/wiki/Insulated_glazing

   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. In the summer, a window screen would be installed on the exterior over the double-hung window to keep out animals and insects.

4. R-value (insulation) - Wikipedia

   en.wikipedia.org/wiki/R-value_(insulation)

   If the interior of a home is at 20 °C and the roof cavity is at 10 °C then the temperature difference is 10 °C (or 10 K). Assuming a ceiling insulated to RSI 2.0 (R = 2 m 2 ⋅K/W), energy will be lost at a rate of 10 K / (2 K⋅m 2 /W) = 5 watts for every square meter (W/m 2) of ceiling. The RSI-value used here is for the actual insulating ...

5. Glazing (window) - Wikipedia

   en.wikipedia.org/wiki/Glazing_(window)

   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 ...
