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]
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 ...
Quadruple glazing is a subset of multipane (multilayer) glazing systems. Multipane glazing with up to six panes is commercially available. [1] Multipane glazing improves thermal comfort (by reducing downdraft convection currents adjacent to the windowpane), and it can reduce greenhouse gas emissions by
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 ...

Jingdezhen, a hub for Chinese ceramic production in Jiangxi, was a main source of high quality porcelain that dominated the international Chinese porcelain market. [2] By the end of the 14th century, primary production sites in Jingdazhen shifted from bluish-white colored wares to predominantly blue-and-white porcelain. [2]
The Knightsbridge Residences is located within the former location of the 4.8-hectare International School Manila, which 3.4 hectares was sold to Century Properties Corporation (the remaining was sold to Picar Properties) in a bidding by the Philippine Government in 2007.
