Which Renewal by Andersen® Glass Option Is Right for You?

When it’s time to get new replacement windows for your home, it’s a good idea to consider the multiple glass panes in insulated glass units (IGUs) instead of the old single-pane glass windows of old. Renewal by Andersen® manufactures and installs multiple-pane glass windows that help conserve energy and make for a more comfortable indoor environment.

In this post, you will learn about the type of glass that comes with your new windows.

High-Performance™ Low-E4®

Our windows and doors come with High-Performance™ Low-E4® dual-pane glass as a standard feature. This is the glass for areas that experience plenty of sun and minimal cloud cover. It can filter out the sun’s heat while allowing in plenty of light. This is ideal for all climates.

High-Performance Low-E4 SmartSun™

Upgrade to this type of glass for all the benefits of Low-E4 glass plus up to 95% filtration of the sun’s harmful ultraviolet (UV) rays, all while providing your home with lots of daylighting. High-Performance Low-E4 SmartSun™ is also ideal for all climates.

High-Performance Low-E4 SmartSun With HeatLock® Technology™

Upgrade to High-Performance Low-E4 SmartSun glass with HeatLock® Technology to enjoy the benefits of SmartSun plus a special coating that saves energy and reflects heat back into the room. Enjoy warmer indoor environments during even the coldest winters with this glass option.

High-Performance Low-E4 Sun Glass

Sun Glass offers outstanding thermal performance with the benefits of High-Performance Low-E4 glass plus a subtle tint for added heat blocking. This is the perfect choice for homes in southern climates.

High-Performance Low-E4 PassiveSun® Glass

For homes in northern climates, ask your windows company about PassiveSun® glass. This protects you in cold weather and allows the sun’s heat to enter your home, leading to savings in indoor heating.

"Very pleased with installation of six windows and a ProVia entry door. I love the look of the windows and door. I am pleased that my wife is thrilled with the look of the door. She is very pleased that the bronze color fits in well with the color of the brick."

"I just had my Renewal by Andersen windows installed and couldn’t be happier, the entire process went very smoothly. The windows are high quality and look great. But the installers Roy, Zack and Jordan were the stars, they introduced themselves upon arrival walked me thru everything they were going to do and when they finished took me to each window to make sure I was completely satisfied. They were clean and courteous and I would definitely recommend and have them work in my home again."

"Wonderful experience with knowledgeable, competent employees. We had Andersen windows in a previous house & didn’t even consider anything else this time. After replacing our patio door almost two years ago, we replaced all our windows this year. What a difference over builder-grade windows, especially in the really cold temperatures we’ve had this year. Andersen windows may be a little more expensive than other brands, but they are top quality."
