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 ...

   en.wikipedia.org/wiki/Cooling_load_temperature...

   The SC, or shading coefficient, is used widely in the evaluation of heat gain through glass and windows. [1] [5] Finally, the SCL, or solar cooling load factor, accounts for the variables associated with solar heat load. These include the global coordinates of the site and the size of the structure. [1] [5]

6. Glass brick - Wikipedia

   en.wikipedia.org/wiki/Glass_brick

   Glass brick has an r value between 1.75 and 1.96, close to that of thermopane windows. [1] [2] There are newer glass blocks injected with argon gas and having a layer of low-emissivity glass between the halves, which increases the insulative (U) value to 1.5 W/m 2 ·K, which is between triple glazed windows (1.8 W/m 2 ·K) and specialty double ...

7. Window film - Wikipedia

   en.wikipedia.org/wiki/Window_film

   Ceramic window films cost slightly more but provide a substantial increase by reflecting and absorbing infrared radiation (IR or radiant heat). To keep the sun's heat out of the house, a low-emissivity coating should be applied to the outside pane of glazed windows. If the windows are designed to provide heat energy in the winter and keep heat ...
