When did double pane windows start?

A single-paned window with one sheet of glass is an older style that has since been replaced by the more popular and energy-efficient double-paned window. Though double-paned windows were introduced commercially in the 1950s, they became common in homes around the 1970s.

When did double glazing become popular?

From the 1980s onwards, double glazing became standard for new UK homes. Although only about 8% of UK homes featured double glazing in the 70s, the concept quickly took off and now 93% of homes in the UK are fitted with double-glazed windows.
