Energy-Efficient Windows Are a SoundSpacious bathroom with standalone bathtub, wood flooring, and four large energy-efficient windows overlooking landscape. Investment for Your Wausau, WI, Home

Wisconsin may be beautiful, but it certainly has its fair share of frigidly cold—and excessively warm—days. You can ensure your Wausau home is prepared by turning to RBA of Greater Wisconsin for energy-efficient windows. Our replacement windows are designed with a plethora of insulative properties to ensure that no matter what the temperature is outside, you can remain comfortable inside.

What Makes Our Windows Energy Efficient?

While many window companies advertise their replacement windows as being energy-efficient, we at RBA of Greater Wisconsin can back our claims. Our energy-efficient windows are crafted by Renewal by Andersen®, our parent company, which earned the 2020 ENERGY STAR® Partner of the Year award for Sustained Excellence. This is largely due to RBA’s exceptional windows, which are crafted with:

Fibrex® Frames

While there are plenty of windows on today’s market that are made from materials of reasonable quality, none of them compare to the Andersen-exclusive composite material: Fibrex®. Since it boasts superior thermal-insulating properties, you can count on these frames to help keep heat where it should be.

High-Performance Glass

The glass of your windows is just as important as the frames when it comes to energy efficiency. This is why our energy-efficient windows are equipped with high-performance glass and low-E coatings, which keep harmful ultraviolet (UV) and infrared (IR) sunrays from entering the home.


Air can infiltrate a home through gaps between its windows and their openings. But with energy-efficient windows from Renewal by Andersen, that won’t be a concern thanks to our seamless weatherstripping. It will not only prevent heat transfer but also keep any dirt/ debris from slipping through cracks.

Benefits Beyond Improved Energy Efficiency

A potential decrease in your monthly cooling and heating costs isn’t the only thing you’ll enjoy from having our energy-efficient windows installed at your Wausau-area home. These replacement windows will also:

  • Complement your existing home design – With an array of interior and exterior colors, hardware finishes, and optional grille patters available for you to select from, you can customize your new house windows how you see fit.
  • Fit virtually any window opening on your home – Our energy-efficient windows are available in many popular styles, including double-hung, casement, picture, bay, bow, and awning.
  • Last for years to come – Thanks to their aforementioned Fibrex® frames, our replacement windows won’t fade like vinyl, rot like wood, or corrode like aluminum.
