What to Look for in Energy-Efficient Windows

As Wisconsin Winters Approach, Are Your Windows Ready?

Wisconsin winters are fierce, with subzero temperatures and relentless snowfall. If your windows aren’t built to handle the cold, you could be losing hundreds of dollars in heating costs, not to mention comfort. That’s why choosing the right energy-efficient windows before winter is one of the smartest decisions you can make for your home.

At Renewal by Andersen, we specialize in helping homeowners prepare for the harshest seasons. Here’s what you should look for in energy-efficient windows.

Low-E Glass Coatings

Low-emisivity glass (Low-E) is a must for cold climates. This type of coating reflects heat back into your home, helping maintain a consistent indoor temperature. It also blocks UV rays that can fade flooring and furniture.

Tip: We design our High-Performance ™ Low-E4® SmartSun™ glass is specifically for extreme climates, keeping heat in and cold out.

Multiple Panes with Insulated Gas Fills

Single-pane windows don’t stand a chance in a Wisconsin winter. Look for double or triple-plane windows that have argon gas fills between the panes. These gases act as invisible insulation, reducing heat transfer.

Tip: Triple-pane windows offer the best performance in norther climates like ours.

Durable, Low-Conductivity Frames

Aluminum and vinyl window frames are a major source of energy loss. Renewal by Andersen windows use our exclusive Fibrex® material, which combines the strength of wood with the low-maintenance performance of vinyl. This makes Fibrex® material 7x more insulating than aluminum.

Proper Sealing & Weather Stripping

Even the most advanced window won’t perform well if it’s poorly sealed. Ensure the windows you choose come with airtight seals and top-quality weatherstripping to prevent drafts and heat loss.

Tip: All our energy-efficient windows are custom-fit and professionally installed to eliminate gaps that cause energy loss.

ENERGY STAR® Certification

The ENERGY STAR® label is your assurance that the windows meet or exceed energy-efficiency guidelines set by the U.S. Environmental Protection Agency. In a climate like Wisconsin’s, this label is incredibly valuable.
