The Benefits of Marvin Windows

Although founded in 1912, it wasn’t until 1945 that Marvin began making windows, and the impetus behind that decision wasn’t profit but to open up additional jobs for servicemen returning from World War II. But the company was a natural fit, and in 1952, it gained national attention with a Sack and Strip window that could be used as an awning, casement, or hopper. In 1978, Marvin became the first window company to have its entire product line certified, and by the 1990s, Marvin had become a standard for residential windows, which Money magazine recognized in its “99 Things Americans Make Best.”

Marvin windows are manufactured from premium materials and built to last. There are a wide range of material and design options, and these windows will enhance your home’s curb appeal and your property value while lasting for decades with little to no maintenance. Windows by Marvin are highly energy efficient as well and will make a real difference in what it costs to cool and heat your home.

Many Different Window Materials

Marvin windows are made from many different materials as well. Those include real wood, which is a traditional choice, but also fiberglass, which has become a popular modern alternative.

Marvin Wood Windows

Wood is the classic choice for residential windows and provides an unmatched elegance and charm. Marvin offers both wood and wood-clad windows through its signature collection, which features three notable series: Coastline, Modern, and Ultimate. Wood windows are timeless and suitable in all climates, and they’re a superior insulator that provides better energy efficiency than most other materials.

Marvin Fiberglass Windows

Marvin Fiberglass Windows

Fiberglass windows are affordable and require next to no maintenance over their long lifespans. Marvin windows made from fiberglass are available through two core collections: Essential and Elevate. The Marvin Essential collection combines performance, quality, and design into a streamlined series, and Marvin Elevate delivers remarkable design and superior strength with striking aesthetic options like Gunmetal.

Many Types of Window Styles

Another great reason to choose windows by Marvin is the many types of windows it offers. These include double- and single-hung windows, which are the most prevalent residential window style, but also awning, bay, bow, casement, corner, picture, sliding, and specialty shape windows.

Vinyl Window Replacement

Vinyl is not currently an option among Marvin windows as the brand focuses on its proprietary fiberglass. Our company does, however, offer a wide range of vinyl replacement windows from other leading brands, including Andersen and Pella. Vinyl windows tend to be more affordable than fiberglass, and while fiberglass windows tend to last longer, the total cost of ownership is often similar or even superior to vinyl.
