You see it on many items these days…the Energy Star logo. But what does it really mean? Products can only sport the Star if they have been rigorously tested. The National Fenestration Rating Council or NFRC is an independent, non-profit organization whose only mission is to test products to see if they truly are energy efficient. They provide an apples to apples scoring system which allows consumers to make the best decision about home products. Ratings are clear, concise and make decisions homeowners face just a little easier.
According to Energy Star statistics, replacement windows that are labeled with Energy Star ratings, on average can improve energy efficiency between 7 and 15 percent. Over the life of a window that can add up.
As we live in a Northern climate, windows can make all the difference. New materials have made vinyl replacement windows virtually maintenance free. Low E glass reflects infrared light – maintaining cool temperatures in the summer and help keep the warmth in during the winter. Multiple panes of glass help with insulation as well. Many replacement windows contain argon or krypton gas – a much better insulator than plain old air. They are both odorless and non-toxic. Warm edge spacers keep the panes of glass at a optimal distance which also helps boost energy efficiency.
Major brands such as Harvey, Simonton, Certainteed, and Andersen windows all carry the Energy Star rating. Aside from their energy efficiency - they are all quality products with warrantees that will last for years, keeping your home safe from wind, rain, and cold.
