> What fraction of apartment buildings in California have double-pane windows?
One thing that amazed me when moving to California a couple of years ago was reading ads for apartments where the text would gush about the apartment having double glazing!!!1!!
Meanwhile, in Sweden, triple glazing has been the required minimum since the 90s, and older buildings were forced to install a third pane or retrofit new windows or somehow bring it up to code.
These days you can get quadruple glazed windows, but they offer only a very small improvements to triple glazed, so there's not much use.
- adrianN 8y agoSweden is a lot colder than California, it's not surprising that better insulation is required.
- henrikschroder 8y agoIs triple glazing common, standard, or required in any part of the US? Is double glazing?
- pkaye 8y agoDouble glazing is common for all new installs. And people will tend to use them for retrofits unless they are trying to cheap out. As for California, it doesn't get cold enough here to pay the premium for triple glazing.
- cafard 8y agoFor some years I lived in a rowhouse in the Maryland suburbs of DC, built about 1983. The units there had double glazing. Maryland does not have an especially cold climate. Where I live now we have single panes, but behind storm windows. On the other hand, we know a family near Boston who live in a big old house. The husband, a mathematician, calculated that they would never recover the cost of replacing the windows. I don't know how far out he calculated, but I expect it was about 20 years.
