One of the questions we hear most often is about the difference between single-pane windows and double- and triple-pane windows, so it is a topic worth revisiting here in our blog.

Whether you are choosing the perfect windows for your new home or replacing your existing windows, it is important to understand the pros and cons of each product so that you can choose the windows that best fit your budget, style, and desired energy efficiency.

Let’s take a look at the differences between each one.

Single-Pane Windows

Single-pane windows, as their name implies, are made with one layer (or pane) of glass. Though you can typically find them in the same styles and materials as double- and triple-pane windows, they are not as effective at insulating the home from noise pollution or seasonal temperature changes. However, homeowners who live in mild climates and quiet neighborhoods may lean toward single-pane windows as a budget-friendly option. Just keep in mind that the overall cost of single-pane windows will likely increase over time because they are less energy efficient.

Double-Pane Windows

In contrast, double-pane windows are made with two individual layers of glass with space in between them. The separated layers of glass act as a buffer and capture cold temperatures and high heat before they can leak into your home. This unique design also helps to reduce noise pollution. While not 100% sound-proof, double-pane windows are able to significantly reduce the sound of traffic and general neighborhood noises that may keep you up at night.

Double-pane windows generally result in a large return on your investment due to their energy efficiency and will likely add to the overall value of your home. According to the U.S. Department of Energy, heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use. Even the most basic double-pane windows can significantly reduce energy usage during the summer and winter months and in turn lower your energy bills.

Triple-Pane Windows

If you are looking for added security, superior energy efficiency, and excellent noise reduction, triple-pane windows are the best option. Though similar to double-pane windows in many ways, there are a few key differences. For example, triple-pane models can fill the space between the middle and inner window pane with insulating gas, such as argon, to double the amount of inert gas within the window. This acts as a highly effective insulator against radiant thermal heat from the outside, which is particularly beneficial for homes in hot climates (such as here in Arizona). In addition, triple-pane windows attract little to no condensation as a result of their inherent energy efficiency. They are also much harder to break and a great deterrent against would-be intruders.

A quick note about “Hung” vs. “Pane” 

We know that “pane” refers to the panes of glass in each window style, but what about “hung”? This term actually refers to the number of moveable sashes on a window. Sashes are the panels that hold the window panes together, and most windows have two sashes (an upper and a lower sash). The difference is that on single-pane windows, the upper stash is typically stationary, meaning it does not move, while on double-hung windows both sashes are moveable.
