Single Pane vs Double Pane Windows: What’s the Difference?

single pane vs double pane

The type of windows you have in your home can either make you save or spend money.

And we’re not just talking about style or material. The number of glass layers in your window (single pane or double pane) can have a big impact on the comfort of your home.

But what’s so different about the two?

Take a look at this single pane vs double pane guide to learn which type of window is the best choice for your home.

What Are Single Pane Windows?

Single pane windows have only one layer of glass, which means they have no insulation.

Windows with only one layer of glass aren’t able to block outside noises or temperatures from entering the house. If you live near a busy street, the sounds of driving cars will be louder than they would with double pane windows.

The outside temperature also affects the inside of your home more with single pane windows. Your house will get colder during the winter and warmer during the summer.

To keep the house comfortable, you’re air conditioner or heater will have to work harder. In other words, you spend more money on your energy bill.

Double Pane Windows

Instead of one layer of glass, double pane windows have two. These two layers are separated from each other by another thin layer of empty space. The air trapped inside this space serves as the window’s insulation.

This is how it works.

The air between the two sheets of glass traps the outside temperature inside with it. For example, as the winter cold makes its way through the first layer of glass, it gets trapped in the middle space. This means it never makes its way through the second layer of glass and inside the house.

Because the outside temperature doesn’t affect the inside of your home, you don’t have to spend extra money keeping your house comfortable. In fact, your savings with a double pane window can be as much as 24% during the winter and 18% during the summer.

The double panes also block noise from entering your home as well.

Double pane windows do cost more than single pane windows, but they keep the temperature in your home consistent. So you can lower your heater and turn off your air conditioner.

Which Type of Window Is Better?

In most cases, you’ll want double pane windows for your home, but there are a few situations where you might benefit from single pane windows.

For example, because there is only one layer of glass, single pane windows are less expensive than double pane windows. This can be helpful for people who don’t have a lot of money to spend on their windows.

Just remember, single pane windows may cost less to install, but over time, they’ll make your energy bill rise.

But this might not be an issue if the temperature where you live stays mild and consistent all throughout the year. If you don’t have to worry about your house getting too cold or too hot, single pane windows could be a cost-effective option.
