Energy efficient windows are windows that consist of 2 or more panes. They are also known as double or triple glazed windows. As the windows are thicker, they can keep the house warmer for longer in the winter and colder in the summer. They are a good investment, because they help to keep the house temperature a comfortable level without requiring you to turn the heating on every 30 minutes.

Installing double or triple glazed windows can help lower your electricity consumption. Lowering your electricity consumption can help save the environment and make you one more step closer to being sustainable.
