2. Insulated glazing - Wikipedia

   en.wikipedia.org/wiki/Insulated_glazing

   A typical installation of insulated glass windows with uPVC frames. Possibly the earliest use of double glazing was in Siberia, where it was observed by Henry Seebohm in 1877 as an established necessity in the Yeniseysk area where the bitterly cold winter temperatures regularly fall below -50 °C, indicating how the concept may have started: [2]

3. Double-skin facade - Wikipedia

   en.wikipedia.org/wiki/Double-skin_facade

   Apart from the type of the ventilation inside the cavity, the origin and destination of the air can differ depending mostly on climatic conditions, the use, the location, the occupational hours of the building and the HVAC strategy. The glass skins can be single or double glazing units with a distance from 20 cm up to 2 metres.

4. Window insulation - Wikipedia

   en.wikipedia.org/wiki/Window_insulation

   Energy-efficient houses in cold climates often feature triple-glazed windows with a U-value between 0.19 and 0.26. In moderate and hot climates, quality double-glazed windows with a U-value of about 0.30 are generally a more cost-competitive and effective choice. [8]

5. Glass brick - Wikipedia

   [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 glazed windows with advanced frame and coatings(1.2 W/m 2 ·K).

6. Curtain wall (architecture) - Wikipedia

   en.wikipedia.org/wiki/Curtain_wall_(architecture)

   Unitized curtain walls entail factory fabrication and assembly of panels and may include factory glazing. These completed units are installed on the building structure to form the building enclosure. Unitized curtain wall has the advantages of: speed; lower field installation costs; and quality control within an interior climate-controlled ...

7. 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 ...
