ENERGY STAR is an international symbol of energy efficiency. It helps you quickly and easily identify the most energy efficient products available to help you save energy, money and protect the environment.
The ENERGY STAR® label for residential windows simplifies your purchasing decisions. You can be confident that ENERGY STAR®-labeled windows, doors and skylights exceed the minimum energy efficiency criteria for the climate region in which you live - sometimes by as much as 40 percent! This means that ENERGY STAR® window products will reduce your home energy costs compared to other products.
Energy efficient windows will also increase comfort, cut down noise levels from outside the home, have less condensation in cold weather than standard products, and allow fewer ultraviolet rays to pass through glazed areas, protecting from sun damage. Last but certainly not least, by reducing your home's energy consumption, ENERGY STAR qualified windows, doors and skylights also reduce greenhouse gas emissions that are contributing to climate change.
Energy rating of 45 on Casement Windows supplied by Sunview Windows company , the highest in Alberta.
