How to Choose Energy-Efficient Windows Built for Wisconsin

Winter is Coming. Is Your Home Ready?

If you’re a Wisconsin homeowner, you know how brutal winter can be. Between icy winds and freezing temperatures, your windows become more than just a view to the outside; they’re your first defense against energy loss. Upgrading to energy-efficient windows for winter in Wisconsin is one of the most important steps to improve comfort, reduce heating costs, and protect your home from harsh winters.

Here’s what to consider when evaluating new windows before the cold settles in.

Look for Advanced Glass Technology

The glass in your windows plays a critical role in energy performance. Choose windows with Low-E coatings that reflect indoor heat into your home while allowing natural light to pass through. This reduces heat loss and helps lower your heating bills.

Tip: Our SmartSun™ Low-E glass offers maximum energy efficiency without compromising on clarity or brightness.

Double or Triple-Pane Insulation Matters

In Wisconsin’s climate, single-pane windows are not enough. Instead, opt for double or triple-pane glass with argon or krypton gas fills between layers. These inert gases add extra insulation, keeping your home warmer in winter and cooler in summer.

Tip: The more panes and insulation, the better your window can resist extreme temperature changes.

Choose Insulating Frames

The material of your window frame impacts how much heat is lost. Old aluminum frames can easily transfer cold, creating drafts. Our Fibrex® composite frames offer superior thermal performance and maintain durability over time, even through freezing and thawing cycles.

Check for Air-Tight Installation

High-quality, energy-efficient windows won’t do much good if they’re installed poorly. Ensure your new windows come with expert installation and proper weatherstripping to eliminate gaps where cold air can seep in.

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.
