When getting new replacement windows, you may be debating if you should go with double or triple-pane glass. You may be asking yourself if that extra layer is worth the cost and what the additional benefits are. As you’ll see, the easy answer to the double-pane vs. triple-pane windows debate is to go with the double-pane windows. However, it depends on many factors that are unique to the home, the climate, and the owner’s preferences. In this article, we’ll go over each window’s functions and limitations to help you decide which option is best for you.

Double Pane Windows

If you want to get the most bang for your buck, double pane windows are the way to go. Double-pane windows are one of the most popular options for homeowners because they come with great benefits at a reasonable price. They’re significantly better than single-pane windows and will reflect 90% of energy while letting 10% through. This means that only 10% of the sun’s heat will get through during a hot summer day. During winter, 90% of your furnace’s heat will stay inside the home, and only 10% will escape. With only 10% of the heat escaping, it will be much easier for your heating system to keep your house warm. Since most homeowners don’t live in an extreme or fluctuating climate, double-pane windows are sufficient and will do a great job at insulating your home.

Triple Pane

Triple-pane windows are significantly more expensive than double-pane. So the question is if they are worth the extra cost. If you plan on living in your house for at least 20-30 more years, triple-pane windows may be worth it. Over this timeframe, the amount you save on your energy bills will be similar to the amount you paid for them, equaling out the extra cost. They will reflect 97% of energy, only allowing 3% to pass through the windows. Similar to how the double pane windows work, they will only let in 3% of the sun’s heat during summer, and during the winter, only 3% of your furnace’s heat will escape. Because of the minimal energy loss through your windows, your heating and cooling bills be lower, however not much more than with the double-pane windows.

While triple-pane windows have some benefits, we have to address some of their drawbacks. Yes, the third pane of glass does help preserve energy within your home, but it’s not an incredibly dramatic difference. While one pane of glass makes a big difference from single-pane to double-pane, it doesn’t make as significant of a difference from double-pane to triple-pane. From a financial perspective, depending on how much energy loss you currently have, the upcharge to triple-pane windows may take 20 or even 30 years to recoup the cost. While you may think that an added layer of glass will significantly reduce outdoor noise, it actually doesn’t make that much of a difference compared to double-pane glass. You also need to consider that triple-pane windows are heavier, so you need to be sure your home can handle the weight, which can make the installation process a little tricky.
