Window Replacement; Frames and Materials

Windows also come in a variety of materials – wood, aluminum, fiberglass, and vinyl replacement windows. For years wood was the most common frame type, but in recent years vinyl and fiberglass have become popular as well. In fact, wood is slowly evolving into the "handsome," high-end choice for window frames. Wood is natural, beautiful, and renewable. The other materials are growing in popularity, however, in part due to the fact that they are easier to install and maintain. In addition to all these options, you must also think about whether you want insert or full-frame window replacements. Here is a brief overview of some of the more common types of replacement windows and materials.

Aluminum Window Frames - Aluminum was really the first non-wood replacement window, and they were very popular in the 1950s and the next few decades. Aluminum windows are very strong, don't have to be painted, and are highly effective at noise reduction. As a metal, however, they are good conductors, which isn't exactly a benefit. In fact, they conduct heat approximately 1,000 times faster than wood or vinyl. Once you settle on a window type, there are still many decisions to make. You'll have to decide whether you want inserts or full frame replacements, and whether you feel confident enough to install them yourself or you should hire an installer. In any case, making the decision to replace your windows and make your home more energy-efficient is a wise and rewarding decision.

Composite and Fiberglass Window Frames - Composite material is a mixture of substances, in this case ground-up vinyl with sawdust or wood chips, with epoxy as binding agent. Some manufacturers use recycled plastic or vinyl to make their composite windows. Composite windows are strong, and resistant to wear-and-tear. Fiberglass windows are highly stable and in fact much stronger than vinyl frames. Fiberglass frames are about three times stronger than aluminum and nine times stronger than vinyl. They are easy maintenance, come in many colors, and, like vinyl, they resist cracking and corrosion.

Wood and Vinyl Window Frames - Once the most common type of window material, wood is now more expensive and has become the elegant and environmental choice for many. Natural and renewable, wood requires staining or painting and some maintenance. Wood is also prone to warping, termites, and rot. To minimize maintenance, some manufacturers clad the exterior side of wood windows in vinyl or aluminum. Wood composite frames, made from wood fibers and plastic resins, are another option. They have wood's look and durability and plastic's easy maintenance. Vinyl replacement windows are a great choice because they are cost-efficient, and easy to install and maintain. Color choice is somewhat restricted, although some manufacturers now offer more color options through surface treatments and coatings.
