A LOOK AT RENEWAL BY ANDERSEN® WINDOW GLASS OPTIONS

A Look At Renewal By Andersen Window Glass Options

This article discusses one key component of energy-efficient windows: glass packages.

Window Glass Qualities

Renewal by Andersen glass provides the necessary heating, cooling, visible light transfer and ultraviolet (UV) protection qualities you are looking for in an energy-efficient window. It utilizes a state-of-the-art technology, both on the exterior and the interior.

On the exterior of the glass, the metal oxide coating is applied to enable easy surface cleaning. When activated by sunlight, the likelihood of water spotting is reduced to 99%. Meanwhile, a light, multi-layer low emissivity (Low-E) coating is applied on the glass interior. This allows for visible light to pass through the glass while reflecting heat. With this coating, you remain comfortable both during summer and winter months.

Glass Options

Before windows installation begins, you will have to choose which glass option is best for you. The climate you live in, the architectural design of your home, the placement of your windows in relation to the sun and your desired “custom climate” are some of the factors you need to consider.

Your options include the following:

  • High-Performance™ Low-E4® glass – Standard for all windows we manufacture, it blocks 83% of harmful UV rays. It is effective in improving energy efficiency by up to 47% in the winter and 56% in the summer in comparison to ordinary dual-pane glass.
  • High-Performance Low-E4 SmartSun™ glass – It provides better energy efficiency by up to 49% in the winter and 70% in the summer. It has the best daylighting capabilities while blocking the sun’s heat.
  • High-Performance Low-E4 Sun glass – This glass has a tint coating that brings in just the right amount of visible light while keeping your home cooler during warm weather.

Reviews

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
