Fiberglass is a strong material used for window frames. According to Greenerbuilding, an organization dedicated to promoting the use of sustainable construction materials, fiberglass is about three times more durable than aluminum and nine times tougher than vinyl. In addition, fiberglass is paintable and is more energy efficient than other windows. Despite these benefits, problems have been reported with fiberglass windows.
When considering new or replacement windows, homeowners have many more options than they used to. The oldest modern windows, and many still today, are made from wood, while the newest material for frames and sashes is fiberglass. While it may seem that fiberglass is a vast improvement, and in many cases it is, wood windows still have their place.
Over the life of your home, you will probably replace your windows for either energy efficiency or aesthetic purposes. When you select replacement windows, deciding whether to purchase vinyl or fiberglass is one of the first steps.
