If you're working on updating your home, you may consider upgrading the windows. Choosing the right windows for your home requires a multitude of decisions, from the number of glass panes that you want and the style of the window itself to the R-value and UV ratings of the window. A window professional can help you understand the jargon, but it helps to know a little bit ahead of time. Below, you will learn about the difference between single, double and triple pane windows.  

What's the Difference?

  • Single-Pane Windows – The majority of older homes, have single-pane windows. These are the least energy-efficient of all windows because they only have a single pane of glass, just as the name suggests.
  • Double-Pane Windows – Double-pane windows are pretty popular, especially in newer homes. These windows consist of two separate panes of glass that are separated by non-toxic gases that help keep the sound out and improve insulation properties.
  • Triple-Pane Windows – These windows are just like double-pane ones except they have three panels of glass instead of just two. With the added panel of glass, triple-pane windows are the most energy-efficient, durable and sound-blocking.

Which Type of Window Should You Select?

In order to make a well-informed decision, it is important to understand what each type of window can offer you.

  • Single-Pane – Single-pane windows are the cheapest, but they are not energy-efficient. They are not well insulated or durable. Therefore, they are not a good choice when you're remodeling your home. After all, you're trying to upgrade your home, not downgrade it or keep it the same.
  • Double-Pane – Double-pane windows are next in terms of cost and energy efficiency. They are durable and can offer good sound transmission while also helping to keep your energy bill at a minimum. In fact, when compared to single-pane windows, you can save as much as 24 percent in the winter and 18 percent in the summer.
  • Triple-Pane – Triple-pane windows will offer more comfort, durability and quietness than double-pane windows, but it may not necessarily be worth the extra price for them. When compared with double-pane, triple windows make it possible to save two to three percent more on your energy bill in cold regions. However, it could take several decades before you can recoup the 10 to 15 percent extra that you paid for the windows to begin with.

What Else Should You Keep in Mind?

If you don't want to splurge on triple-panes throughout your entire house, the Family Handyman suggests only getting them for the east- and north-facing rooms. Then, you could upgrade to double-pane windows for the rest of them.

Ultimately, an energy-efficient window involves more than just choosing the number of glass panes you want. A good window requires a combination of the right glass, the most appropriate frame and quality installation. To ensure that you are getting the most bang for your buck, contact a window installation professional in your area who can provide some insight before you make a final decision.
