Double-Pane Windows: A Look at Their Advantages

Apart from the frame material, the type of glass is also a major factor to consider when choosing replacement windows. Double-pane windows offer many benefits, most notably increased energy efficiency and better indoor comfort all year round.

Double Pane Windows A Look At Their Advantages

About Double-Pane Windows

Also known as dual-pane windows, these are windows that feature two glass panes glazed to the sash and then placed in the window frame. Before this innovation, window products only had a single sheet of glass that protected the home’s interior against the elements. Unfortunately, they lacked thermal control and didn’t help in providing insulation.

Double-pane replacement windows, particularly ones that are energy-efficient, come with an inert gas fill between the two panes of glass. Krypton or argon is added to minimize convection currents within the space, which helps improve thermal efficiency by reducing heat transfer between the inside and outside of your home.

Advantages of Double-Pane Windows

Double-pane windows cost more than single-pane windows, but the impact on your energy bills will be evident. Less heat and cold get transferred through your windows, which means better comfort and energy efficiency. In fact, HomeAdvisor® states that double-pane windows can help reduce energy usage by up to 24% in the winter and 18% in the summer. The energy savings you accrue over time can exceed the initial cost of these windows.

Dual-pane windows also preserve your home’s serene ambiance by minimizing sound penetration. With an additional pane of glass, you can be sure outside noise won’t infiltrate your home. If you live on a busy street or in a noisy neighborhood, these products are truly worth considering.

When choosing which double-pane windows to purchase, consider glass with special coatings that prevent ultraviolet (UV) rays from causing your interior fixtures to fade. At Renewal by Andersen® of St. Louis, we offer Fibrex® replacement windows that come with High-Performance™ Low-E4® glass that selectively blocks unwanted UV rays and solar heat while allowing visible light to pass through.

"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!"
