The Best Windows for Wisconsin’s Climate

Living in Wisconsin? Your Windows Need to Work Overtime

From bone-chilling January winds to sticky July humidity, Wisconsin weather is no joke. And if your windows aren’t built for these conditions, you’re probably feeling it through drafts, rising energy bills, or frames that warp or stick. Choosing the right replacement windows isn’t just about looks. It’s about comfort, savings, durability, and long-term performance. Let’s look at the best windows for Wisconsin’s climate

Material Matters: Fibrex® Wins for Cold + Heat

Most windows on the market use vinyl, wood, or aluminum, all of which struggle with Wisconsin’s harsh weather. 

That’s why Fibrex® composite, exclusive to Renewal by Andersen, is the top choice for Midwest homes. It offers: 

  • Strength like wood, but with better resistance to moisture
  • Energy efficiency that beats vinyl and aluminum
  • No warping, cracking, or rotting, even in extreme temps
  • Low maintenance, so you can skip painting or scraping

Bottom line? Fibrex® keeps its shape and seals tight, no matter what the thermometer says.

Energy-Efficient Glass = Year-Round Comfort

Insulated glass is critical for a Wisconsin home. We recommend High-Performance™ Low-E4® SmartSun™ which: 

  • Reflects summer heat while letting light in
  • Retains interior warmth in winter
  • Blocks up to 95% of UV rays
  • Helps lower heating and cooling costs

It’s ideal for four-season climates, and ENERGY STAR® rated, making it perfect for Wisconsin. 

Window Styles That Seal Tight & Vent Well

Wisconsin homes benefit most from window styles that provide tight seals in winter and flexible ventilation in summer.

Best window styles for our climate:

  • Casement windows: Seal tight when closed and open fully to catch breezes. 
  • Double-hung windows: Versatile and great for airflow on mild days.
  • Bay and bow windows: Add visual interest and improve insulation with multiple panes.
  • Picture windows: Perfect for maximizing light and minimizing drafts. 

Proper Installation = Peak Performance

Even the best windows can underperform if installed incorrectly. At Renewal by Andersen, our Certified Master Installers ensure:

  • A perfect fit, no matter your home’s age or style
  • Air- and watertight seals to protect against leaks
  • Clean, professional service that respects your home 

You get performance that lasts, and windows that actually do their job.

Real Savings

Your windows need to protect your comfort and your wallet. Choosing the best materials, energy-efficient glass, and expert installation means:

  • Lower energy bills year-round
  • Better indoor air quality and comfort
  • Longer window lifespan

Hear From Our Customers

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgeable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.
