The Advantages of Thick Glass Windows
Thick glass windows possess distinct advantages over standard builder-grade offerings which have thinner, single-strength glass. The primary one is added durability as they’re much less susceptible to breakage. Thick glass windows also help to reduce sound transmission keeping your home quieter than windows with thinner glass. Unsurprisingly, the lower noise level from thicker glass is very substantial.
Thicker, Double-Strength Glass – It Makes a Big Difference!
People often inquire about thick glass windows because they want information about sound dampening to control noise. While truly soundproof windows don’t exist, there are many ways to reduce sound including the use of thicker glass. In general, the replacement window industry has tried to educate people about the benefits of insulated, double-pane Low-E glass. However, despite this effort few seem to understand the relationship between thicker glass and sound control. In fact, the perks of thick windows are rarely understood even by professional window-sales people.
Ultimately, when defining what constitutes a better window the thickness of each glass pane is an important but often underappreciated feature. This is worth considering as you evaluate your window company and the attributes of the windows you plan to buy.
What is Considered a Thick Window?
There are five basic window glass thicknesses used in modern American window systems. They range from thin 2.2mm to very thick 5.9mm glass. For reference, please refer to the chart shown on this page.
It’s not surprising then that builder-grade windows, which frequently have 2.2mm thin glass, are virtually always the lowest cost and quality. By definition they are cheaply priced and offer substandard performance, durability, and longevity. For a slightly larger investment, you can purchase superior windows with tremendous benefits. Think about it….. Which would you prefer in your house?
Our Thick Glass Windows Reduce Noise
The most common compliment we receive from new clients is that their homes are much quieter immediately after Ringer Windows are installed. We think that’s a pretty big deal! Anyone who’s ever owned a home with builder-grade windows knows how easily outside sounds can come in (as if there is no glass in the windows at all). At Ringer Windows, we ONLY use double-strength insulated glass (or thicker) in ALL our windows.

Terminology Check:
Double-Pane Glass & Double-Strength Glass
People often confuse double-pane with double-strength glass. All Ringer Windows are manufactured with double-pane glass that includes inner and outer panes of hermetically sealed glass.
Double-strength glass refers to the thickness of each individual pane in our windows. We combine double-pane technology AND thicker double-strength glass to provide superior sound control. Our clients are always amazed at how quiet their homes become after installing Ringer Windows. You can learn more about our sound control windows under the options section of our website.
A Useful Tip When Comparing Competitor Windows & Glass Thickness
Regardless of which double-pane windows you buy, it’s wise to ask if they’re made with double-strength or thicker glass. The truth is most windows tend to look alike and it’s difficult for consumers to know the subtle differences between premium insulated and builder-grade windows. A significant builder-grade indicator is the use of single-strength glass (2.2 mm). Nearly all premium windows use double-strength glass (3.0 mm) or thicker. Always demand double-strength glass and get better windows.
