What is the most energy efficient double glazing?
low emissivity
The most energy efficient type of glass for double and triple glazing is low emissivity (low-E) glass. Low-E glass has a microscopically thin coating of metal oxide on one of the internal glass surfaces. This coating reflects heat back into the home but still lets in the light from outside.
