    Fiberglass window frames provide homeowners with a sleek and savvy fusion of classic charm and elite performance. To learn the basics of these frames, take a look at our handy guide below.

    The Basics of Fiberglass Window Frames

    Even a quick glance at what a fiberglass window frame has to offer is impressive. Fiberglass window frames are much stronger and more durable than wood, vinyl, and aluminum window frames. Additionally, fiberglass frames are structurally stable, with air cavities that can be filled with extra insulation. In fact, foam-filled fiberglass window frames have the highest insulation value of any type of window frame. This structure makes them thermally superior to wood or uninsulated vinyl.

    Fiberglass is also highly resistant to rot, water damage, warping, and other standard varieties of disrepair. As such, fiberglass has a much longer life expectancy than most of its window frame counterparts.

    Additionally, fiberglass window frames are designed to resemble wood, allowing them to blend with a classic, natural aesthetic. Fiberglass window frames can be left as they are, but they are also easy to paint, unlike vinyl.

    How Much Will Your Fiberglass Frame Cost?

    Fiberglass’s high performance comes also comes with a higher price tag. Because fiberglass is relatively new to the market and is superior to other types of window frames, it’s more expensive than wood, vinyl, or aluminum. Expect to pay around 50-100% more than you would for a vinyl frame. A double-hung fiberglass window ranges from $600-$1000 per window. A casement fiberglass window ranges from $750-$1250 per window.

    Keep in mind, however, that a fiberglass window frame’s high performance will save you money on energy bills, maintenance, and repairs in the long-term.

    How to Maintain Your Fiberglass Window Frames

    Maintenance for fiberglass window frames is relatively easy, as they are fundamentally resistant to decay. Additionally, fiberglass window frames are resistant to UV rays and won’t expand or contract with changes in temperature, meaning that they’ll maintain their square shape. So, while the initial cost of fiberglass window frames is higher than vinyl, the low maintenance and long lifespan of fiberglass ensures that its long-term costs are very low.

    Fiberglass Window Frames: Energy Efficiency

    Fiberglass window frames are highly energy efficient. Most importantly, they are excellent insulators, which means that they prevent warm air from escaping during the winter and keep cool air inside during the summer. Additionally, fiberglass window frames are often made of more than 50% glass, which is easily recyclable. Consequently, fiberglass window frames are excellent green additions to your home.

    Conclusion: A Strong Investment in Your Windows’ Future

    Fiberglass is one of the strongest and hardest building materials around. As such, using fiberglass window frames will ensure a long lifespan for your windows. Additionally, fiberglass window frames require virtually no maintenance, allowing you to spend your free time relaxing, rather than fiddling with a faulty window.
