Fiberglass Windows Deliver Benefits for Homeowners in Kansas City, MO

Large of various styles in luxury kitchen with adjacent dining areaThere’s never been a better time to replace your home’s windows, thanks to the many options on the market. If you’re a homeowner in Kansas City, Missouri, one of the best choices you can make is to go with fiberglass window frames. Fiberglass doesn’t absorb moisture and it’s far more resistant to shrinking and swelling than either wood or vinyl. This translates into superb resistance to damage from the often-extreme seasonal weather changes we experience in this region.

At Johnson County Siding & Window Co., we heartily recommend choosing high-performance fiberglass windows for your upcoming replacement project. We’ve been outfitting Kansas City homes with long-lasting replacement windows for over 40 years, and we’re proud to offer and expertly install several lines from Marvin®, one of the nation’s top-tier window manufacturers. Here are only two of the reasons why:

Beauty That Derives From Strength

Marvin’s fiberglass windows are striking to behold. The ultra-slender frames are crafted from the manufacturer’s proprietary Ultrex® fiberglass, which is three times stronger than wood and eight times stronger than vinyl. This remarkable strength allows for windows with noticeably large expanses of glass, creating a streamlined appearance as well as exceptional views of the outdoors. What’s more, thanks to the hardwearing fiberglass frames, Marvin windows hold their beauty year after year with practically no maintenance required.

Additionally, as a longtime replacement window manufacturer, Marvin understands the importance of offering lots of aesthetic and performance-enhancing options. This means you’ll have no trouble finding the right color and style to suit your tastes.

Energy Efficiency That Leads the Industry

The strength of fiberglass windows also plays a key role in protecting the seal between the glass and the frame. The replacement windows we install meet or exceed ENERGY STAR® standards, so you can feel confident that they’ll help keep your cooling and heating costs in check, and you’ll be able to enjoy that confidence for decades.

If you’d like to explore your options for replacing the windows of your Kansas City home with fiberglass upgrades, contact Johnson County Siding & Window Co. today. We’ll be happy to set up an in-home consultation as well as tell you about the financing options available to qualified homeowners.


If you know you want to get your home exterior project done, but are feeling stress about paying for it all at once, we can help.
