ENERGY STAR Certified Energy-Efficient Windows for Your Leakwood Home

Homeowners are increasingly interested in choosing energy-efficient windows when it’s time for an upgrade, and Johnson County Siding & Window Co. offers some of the top-rated replacement windows in the industry to our customers in the Leawood area. What’s more, after over 40 years of providing excellence in home window replacement services, we’ve become the go-to experts in this region for windows that are not only energy efficient but also exceptionally beautiful and weather resistant. We’ll be happy to discuss the features that make our windows the ideal choice for homeowners in this part of Kansas so that you can feel confident that you’re getting the best value for your investment.

What Makes a Window Energy Efficient?

Choosing energy-efficient replacement windows will help your home maintain a comfortable indoor temperature year-round with less demand on your heating and cooling systems. As a result, you may enjoy lower monthly energy bills. You may have heard about the ENERGY STAR® program, which was developed to help consumers choose home upgrades that will meet those goals, and it’s a good idea to look for windows that are ENERGY STAR® certified for this region. At Johnson County Siding & Window Co., we’ve selected Marvin® fiberglass windows and ProVia vinyl windows to offer to our customers. Both of these manufacturers custom craft their windows with the latest energy-saving features and techniques, which meet or exceed ENERGY STAR® standards. Some of those features include:

  • Multi-pane glass with inert gas fill for enhanced insulation that can minimize heat transfer
  • Low-emissivity (Low-E) glass coating to reduce the amount of solar heat entering through the window while still letting daylight shine through
  • Warm edge spacer bars that help minimize heat loss through the window seal

Installation Expertise Is Also Key

Even the best energy-efficient windows may not perform as designed if they are not installed properly. At Johnson County Siding & Window Co., all of our window installations are performed by highly trained professionals who strictly follow the manufacturer’s installation guidelines. Plus, we back our installation services with a five-year workmanship warranty, on top of the outstanding product warranties provided by the manufacturers we partner with.

To learn more about the energy-efficient windows we expertly install for homeowners throughout the Leawood area, contact Johnson County Siding & Window Co. today.
