2. Insulated glazing - Wikipedia

   en.wikipedia.org/wiki/Insulated_glazing

   Argon is commonly used in insulated glazing as it is the most affordable. Krypton, which is considerably more expensive, is not generally used except to produce very thin double glazing units or extremely high performance triple-glazed units. Xenon has found very little application in IGUs because of cost. [10]

   Modern louvers are often made of aluminum, metal, wood, or glass.They may be opened and closed with a metal lever, pulleys, or through motorized operators. [3]The Australian Standard specifies requirements for the construction of buildings using louver in bushfire-prone areas in order to improve their resistance to bushfire attack from burning embers, radiant heat, flame contact and ...

   [2] (see also insulated glazing). A typical window insulation film kit, consisting of plastic shrink film (folded-up) and a roll of double-sided tape. One commonly used film is a heat-shrink plastic which is attached to the window frame using double-sided pressure-sensitive tape. A hair dryer is used to remove creases and improve optical clarity.

   Condensation occurs when there's excess humidity inside a home, he says, adding that homeowners experiencing this problem should turn down —or off — humidifiers and remove heavy window coverings.

6. R-value (insulation) - Wikipedia

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

   The resistance of each material to heat transfer depends on the specific thermal resistance [R-value]/[unit thickness], which is a property of the material (see table below) and the thickness of that layer. A thermal barrier that is composed of several layers will have several thermal resistors in the analogous with circuits, each in series ...

   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 ...
