The Best Windows for Wisconsin’s Climate

Why Choosing the Right Windows Matters in Wisconsin

If you’ve lived in Wisconsin for more than a season, you know: our weather is no joke. From frigid winter nights dipping below zero to hot, humid summer days, your home’s windows are on the front lines. Drafty or outdated windows don’t just make your home uncomfortable; they can spike your energy bills and shorten the life of your HVAC system. So, how do you choose the best windows for Wisconsin’s climate? Let’s break down what matters most. 

Window Material: Fibrex® Outperforms Wood, Vinyl & Aluminum

Many window companies use wood or vinyl, but those materials just don’t hold up in Wisconsin’s freeze-thaw cycles. 

Fibrex®, a composite material exclusive to Renewal by Andersen, offers unbeatable benefits:

  • 2x stronger than vinyl
  • Won’t crack, peel or warp, even in extreme cold
  • Superior thermal performance, reducing heat loss in winter
  • Low maintenance with the timeless look of wood

Fun fact: Fibrex® is made from 40% reclaimed wood fiber and thermoplastic polymer, making it both durable and eco-friendly. 

Insulating Glass That Stands Up to the Seasons

Our windows are available with High-Performance™ Low-E4® glass, which reflects heat in the summer and retains warmth in the winter. For Wisconsin homes, this glass helps: 

  • Prevent heat loss during bitter cold spells
  • Reduce solar heat gain during summer heat waves
  • Block UV rays that can fade flooring and furniture

The result? A more comfortable home year-round and lower energy bills to match. 

Weatherstripping & Airtight Installation = Total Protection

Even the best window won’t perform if it’s poorly installed. Wisconsin weather calls for: 

  • Professional installation to prevent drafts and moisture intrusion
  • Precision-fit weatherstripping to eliminate air leaks
  • Seamless integration with your home’s siding and framing

At Renewal by Andersen, our certified installers ensure every window is ready to take on whatever the season throws at it. 

Window Styles That Maximize Comfort and Function

In harsh climates, functionality matters just as much as appearance.

Best Styles for Wisconsin Weather: 

  • Casement Windows: Seal tightly and open outward to catch cool summer breezes.
  • Double-Hung Windows: Great for ventilation, and easy to clean from the inside.
  • Bay & Bow Windows: Add natural light and extra insulation with multiple panes.
  • Picture Windows: Ideal for rooms with scenic views and minimal airflow needs. 

Energy Efficiency That Pays for Itself

Between heating bills in January and A/C costs in August, energy-efficient windows are a must in Wisconsin. 

Our windows are ENERGY STAR® certified, which means they:

  • Help maintain consistent indoor temperatures
  • Reduce strain on your furnace and air conditioning
  • Qualify for energy rebates and increase your home’s resale value
