Beautiful & Strong Fiberglass Windows for Overland Park, KS Homeowners

At Johnson County Siding & Window Co., we’ve been in the business of outfitting homes in the Overland Park area with beautiful replacement windows for over 40 years. And we’re often asked what type of windows provide the best combination of beauty, energy efficiency, and weather resistance for homeowners in this part of Kansas. In recent years, that answer has been, hands-down, Integrity® from Marvin fiberglass windows.

The primary reason these windows stand out from the rest is the manufacturer’s proprietary Ultrex® pultruded fiberglass used in construction. Integrity® window frames are eight times stronger than their vinyl counterparts, yet they’re every bit as easy to maintain, needing only an occasional wipe-down with soap and water. Moreover, the extra strength of the fiberglass frames allows these windows to feature a more expansive area of glass. Plus, unlike other window-frame materials, fiberglass doesn’t expand and contract, so Integrity® windows provide a more reliable and longer-lasting seal against air and water infiltration. This is an important feature to consider for homeowners in the Overland Park area, where temperatures can fluctuate from frigidly cold to oppressively hot, depending on the season.

When you turn to Johnson County Siding & Window for fiberglass windows, you’ll receive windows that are made to order to fit the specific openings of your home.
