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.
