Why Is Fiberglass Used in Windows?

Feb 19, 2020

Why Is Fiberglass Used in Windows?Fiberglass is a relative newcomer to the replacement window industry, which has long been dominated by wood-frame and, more recently, vinyl-frame windows. However, many fiberglass fans would argue that the introduction of this remarkable material to window construction was long overdue. The primary virtue of fiberglass window frames is their remarkable strength, which translates into many aesthetic and practical benefits.

Case in point: Marvin® fiberglass windows. An industry-leading manufacturer, Marvin® has taken the brawn of fiberglass and honed it into a critical component of beautiful windows. The company’s exclusive Ultrex® pultruded fiberglass creates sleek, elegant frames that are eight times stronger than vinyl and three times stronger than wood. This results in slender frames and sashes that can cradle large expanses of glass with minimal risk of seal failure, which can lead to air and water infiltration. Additionally, fiberglass is far less likely than vinyl and wood to expand and contract as temperatures change from warm to cold. This characteristic leads to exceptional durability and also factors into the high performance that fiberglass windows deliver when it comes to energy efficiency.

What About Customization Options?

You may have heard that fiberglass windows are less customizable than other types of replacement windows, but that’s not true when it comes to the Marvin® brand. These fiberglass windows are available in all the most popular styles, including specialty-shape windows. Customers have a broad array of exterior frame colors to choose from, as well as the option of having real wood frames for the interior. Plus, the manufacturer’s fade-resistant finish has been independently tested and verified as “best in class,” which means that homeowners can count on its ability to maintain a like-new appearance for decades.

These windows are also ENERGY STAR® certified and available with additional features to maximize their energy-efficient performance.

"Johnson County Siding & Windows did a fantastic job on our home. Rosie and his team kept us informed every step of the way and didn't hesitate to consult with us whenever they had questions (a benefit of us working at home). Not only were we extremely pleased with the results, but a separate contractor who did some different work for us said their work was the best he had ever seen. 100% satisfied. 100% recommended.”
