Replacement Windows Kansas City

Sleek & Durable Fiberglass Replacement Windows for Kansas City Homes

More and more people are discovering the long-lasting beauty and distinctive style that fiberglass windows can bring to a home. These windows are especially well-suited to homes in the Kansas City metro area, and Johnson County Siding & Window Co. is proud to be a leading installer of top-caliber Integrity® from Marvin fiberglass replacement windows for homeowners in this region.

When you choose Integrity® windows, your home will sport windows crafted from the manufacturer’s exclusive Ultrex® pultruded fiberglass, a material that’s far stronger than other window frames. This gives Integrity® window frames the strength to hold a wider expanse of glass, thus providing an exceptionally generous view of the outdoors. What’s more, these fiberglass windows won’t expand and contract the way vinyl and wood windows do when the weather changes from bitterly cold to muggy and warm. This means they resist seal failure better than other types of windows, thus providing your home with superior protection against air and water infiltration.

Other Reasons To Choose Integrity® Fiberglass Windows

Energy Efficiency

Integrity® windows are engineered to meet or exceed ENERGY STAR® standards, so you can rest assured that they will help your indoor areas retain a comfortable temperature year-round while potentially reducing your heating and cooling costs.

Exceptionally Durable Finish

Thanks to the manufacturer’s meticulous techniques, Ultrex® fiberglass windows lead the industry with the highest third-party ratings for enduring finishes. This means your Integrity® windows won’t fade, chalk, peel, or crack for many years after installation.

Aesthetic Appeal

When you choose Integrity® fiberglass windows, they’ll be made to order to fit the openings of your home, and you’ll have numerous customization opportunities. These windows are available in a generous array of styles, from traditional double hung to specialty shapes. There’s also an option for real wood interior frames, which means you can enjoy the unbeatable strength of fiberglass without sacrificing the rich woodgrain textures that can add so much to your home’s interior décor.
