The value of a window in any space is evident: they let in natural light, provide ventilation outlets, and help add to the overall ambiance of a room.

But what goes into choosing the right window for a space? The short answer is it depends on what you’re looking for from a window, aside from an unobstructed view. 

As energy-efficient windows, [double- and triple-pane windows](https://blog.newanglebeveling.com/double-pane-vs-triple-pane-insulated-glass-unit) are the most popular choices for new window installations or replacements. 

Choosing a [double-pane vs. triple-pane window](https://newanglebeveling.com/insulated-glass-units/) for your project isn’t an either/or decision. Both window types offer different benefits and are best suited for certain applications. 

Let’s take a look at what both window types bring to the table.

## Double-Pane Windows: Where Affordability Meets Function 

[Double-pane windows](http://www.windownation.com/blog/post/double-pane-or-triple-pane-windows/) are the most popular window choice in America. 

This comes as no surprise as double-pane windows combine affordability with performance. 

Requiring less material to make coupled with shorter manufacturing times, double-pane windows are a budget-friendly option. 

As the name implies, double-pane windows feature** two panels of glass, which are usually separated by a spacer bar and seals**. The space in between the two window panes is filled with gas, typically argon.

With two panes of glass and a layer of gas creating an **extra layer of insulation**, **double-pane windows help lower heating and cooling bills**. During the colder months, cold drafts are kept out. Conversely, cooler air is kept inside during the warmer months.  

As an added bonus, **this type of window style also helps with noise cancellation**. In other words, double-pane windows offer a barrier from noises outside. 

Double-pane windows aren’t immune to some issues.

If poorly constructed, it's not uncommon for seals to fail prematurely, negating their energy efficiency and noise reduction capabilities. However, partnering with a [trusted glass fabricator and manufacturer](https://newanglebeveling.com/) can improve the quality of the windows for your project, and reduce defects.

Double-pane windows are a bit of an “all-or-nothing” deal. That is, the benefits of double-pane windows won't be realized unless all the windows in a facility or home are either double- or triple-pane.

## Triple-Pane Windows for Optimal Energy Efficiency 

A step up from a double-pane window, a [triple-pane window](https://www.familyhandyman.com/windows/are-tripleglazed-windows-worth-the-extra-cost/view-all/) features an additional pane of glass. Just like double-pane windows, the spaces in between the three glass panes are also filled with inert gas, such as argon or krypton. This kind of [insulated glass unit ](https://newanglebeveling.com/insulated-glass-units/)is alternately referred to as “[triple-glazed glass](https://newanglebeveling.com/triple-glazed-glass/).”

The additional pane of glass allows triple-pane windows to **perform better than double-pane windows** in terms of insulation, noise reduction, and strength.

Triple-pane windows are often installed in spaces where energy efficiency is important, such as:

- Homes in regions where temperatures commonly dip below freezing
- Businesses that create or store temperature-sensitive products

Triple-pane windows do have a few drawbacks. 

Most significantly,** it’s challenging to find a window maker in the United States that manufactures them **-- as they are more popular in Europe. At New Angle Beveling, we [manufacture and distribute triple-glazed glass units](https://newanglebeveling.com/triple-glazed-glass/). 

Being that they require more material make and additional processing, **triple-pane windows are more expensive**, too. 

  

## Situational Considerations for Double-Pane vs Triple-Pane Windows

There are various applications where a triple-pane window is a better option than a double-pane one. Perhaps the biggest reason to opt for three panes over two is if energy costs and overall home comfort are becoming a concern.

Triple-pane windows are estimated to help **home and business owners save up to 3 percent more** in energy bills compared to double-pane windows. This is in addition to helping reduce drafts to keep a space as comfortable as possible.

Triple-pane windows also help create an optimum indoor environment via enhanced noise reduction, which can be especially helpful for consumers located near a populated city, or in close proximity to an airport or railroad track.

However, triple-pane windows are not available in every structure. Due to the weight of the extra piece of glass -- the **balance can be inadequate for the window unit**. If a house or business is built with a single or double-paned window in mind, oftentimes they are unable to accommodate a heavier and thicker window added in post-construction.

One option is to mix and match double-pane with triple-pane windows. Aside from a lower price, **double-pane windows also let in more natural light**, which can be appealing for many consumers depending on the placement in the house and the alignment with the architectural plans.

## Double-Pane Vs. Triple-Pane Windows: A Winning Choice Either Way 

Despite their differences, double- and triple-pane windows outperform standard single-pane windows without question. 

With extra layers providing insulation and noise reduction, both types of windows are a proven investment in keeping a space comfortable. 

Regardless of window type, insulated glass units manufactured by New Angle Beveling are protected with a 10-year, dual-seal warranty. Learn more:
