Fiberglass Windows

Fiberglass windows are certainly one option to consider for your home. Although they only make about one percent of all replacement windows, there are a number of advantages that make them worth a second look. Get the low-down on this versatile replacement window option so you can decide for yourself if they are a viable option for your home.

“Fiberglass windows are strong and durable; much stronger and stiffer than vinyl, which means that it can handle larger and more expansive panes of glass in much the same way that aluminum frames can.”

Benefits Of Fiberglass Windows

Strong And Durable
Fiberglass windows are manufactured out of fiberglass cloth combined with epoxy resins, similar to the way many boats are constructed. This process results in a strong and durable material. In fact, it is much stronger and stiffer than vinyl (it’s about nine times stronger!), which means that it can handle larger and more expansive panes of glass in much the same way that aluminum frames can. They are even stronger than aluminum frames.

Variety Of Options
Homeowners can choose from an all fiberglass window or fiberglass clad. The latter option provides the beauty of wood on the interior of the home with the durability and low maintenance requirements of fiberglass on the exterior. They also come in a variety of shapes, sizes and types and come with a selection of design and energy efficient options.

Endless Color Options
Since fiberglass can be painted, the windows can be any color you wish and can be changed if you update the exterior look of your home. In contrast, vinyl cannot be painted so you are stuck with whatever color you originally order them in. Aluminum can also be painted, unless you opt to order them with a baked on enamel color finish, as can wood windows. The downside to being able to paint these frames is that you have more maintenance over the years to keep them looking their best.

Fiberglass Windows Prices

Fiberglass windows generally cost slightly less than wood clad and above vinyl. They offer exceptional strength and durability and require little care and maintenance. For a standard sized double hung with normal installation, homeowners can expect to pay between $400 and $800 depending on the size, manufacturer and type of installation needed.

Benefits – Energy Efficient

Fiberglass windows come with a wide variety of energy efficient options, including low-e coatings, gas fills and multiple panes of glass. They are typically about as efficient as vinyl windows and more energy efficient than aluminum models. Most frames have metal spacers along with rubber gaskets instead of the super spacers used in vinyl windows (which contain no metal). Although these spacers are not as energy efficient, the difference can be compensated by opting for low-e coatings and gas fills. Another reason that they are so energy efficient is that fiberglass and glass expand at around the same rate, leading to less air leakage.

An Eco-Friendly Choice

Most fiberglass windows are made with a high percentage of recycled material. They also do not release potentially volatile chemicals in the air the way vinyl can do, making them a greener choice in the long term as well (vinyl can continue to release these chemicals for years following initial installation).
