Windows and energy efficiency
The average building is only eight percent glass but that glass is still responsible for:
* 60 percent of the heat loss in winter
* 91 percent of the unwanted heat in the summer
The good news is that glass technology has evolved. There are energy efficient choices, so before you have any glass installed in your home, talk to an expert about the options. If you don’t, you might regret it when your power bills arrive.
