If your home is 50-60 years old and has never had the windows replaced, you will probably find that it has aluminum windows. Back in those days, aluminum provided the only cost-efficient alternative to wood. They used to be a popular option because of being strong, lightweight and able to withstand extreme elements like high wind. They were also a cheap option for builders to install in many homes at once, which is why it is common to see them in older subdivisions.

Technology has come a long way since then and more and more people are moving towards installing fiberglass windows in their homes. They are strong, extremely durable, and long lasting. They can stand up to any weather extremes, and no matter what their age, they always look great.

Fiberglass windows come in a variety of colors that are added in during the manufacturing process, making it last a lifetime. In order to paint aluminum windows, you must clean the frames of any dirt, apply primer and then paint. There is no guarantee how long that will even last in the elements!


Aluminum conducts heat and cold, so it’s not a desirable choice for extreme climates. If you’re looking to reduce your home’s carbon footprint, fiberglass windows are more energy efficient and eco-friendly. Aluminum frames are quickly disappearing in most areas of the country because they no longer meet insulating codes; they also tend to gather interior condensation, causing mold problems.


If you add up the cost of ever-increasing heating and cooling bills, and the potential breakage costs of aluminum windows, it can be far more cost efficient to replace your home windows with a more technically advanced, energy saving material, such as fiberglass.

According to the Energy Star website, with qualified windows your energy bill can lower $126-$465 a year or about 30%. With new windows, you can expect a minimum of 25% and a maximum of 52% savings, your savings will end up paying for the cost of the windows. Consider the cost versus the value when you are looking at replacement windows.

Getting new windows not only improves the look of your home, it also provides comfort and security. The long-term performance and energy savings of fiberglass windows are worth the investment!
