Why Choose Marvin Windows?

Mar 30, 2018

At Johnson County Siding & Window Co., we proudly offer Marvin windows, particularly their Ultrex fiberglass series as a leading replacement window option. You may have already heard of Marvin windows or fiberglass windows before and wondered if they could be any benefit to your home. Marvin is a leading window brand with 100 years in the industry, on par with Pella and Andersen, for a reason. There are a number of ways that installing Marvin windows could improve the quality of your home.

Long Life, Little Maintenance

Marvin windows are known for durability, and Ultrex fiberglass windows can stand up to whatever Mission Hills weather might bring their way. Ultrex is the same material often used in bridge construction. It’s considered by many to be the “perfect building material.” If it can hold up cars day in and day out, it can certainly stand up to harsh storms and debris. In fact, these windows are all but impossible to destroy.

Because these windows can hold their own, they’re easy to take care of. The color lasts for decades without needing to be painted, although these windows can be painted if you change your style. They’re easy to clean and rarely require any further maintenance.

Energy Efficiency

All Marvin windows meet, and in fact exceed, ENERGY STAR guidelines. They’re an excellent way to save money on your energy bills for years to come or add value to your home. Again, the windows durability comes in handy again. Because these fiberglass windows are so tough, cold air doesn’t get into the home from outside and hot air doesn’t leak out. Fiberglass is also exceptional when it comes to keeping cool in the midst of hot weather. Outperforming wood, aluminum, and vinyl, fiberglass windows are known as one of the most energy efficient window materials available today.


Some manufacturers create one or two styles of windows and do them well. Marvin windows offers a variety of window styles, all manufactured with care and quality. At Johnson County Siding & Window Co., we offer Marvin’s Ultrex fiberglass windows. There are options even within their fiberglass selection, however. You can choose windows that are All Ultrex, with a sleek and cool look, or Wood Ultrex, offering the authentic look of wood with the strength of fiberglass. They come in special, custom sizes to fit your home exactly.
