Dual-Pane Replacement Windows

Windows are obviously mostly made of glass, so it makes sense that the kind of glass on your replacement windows is very important. If you’re shopping for replacement windows, you need to be sure you’re choosing the right kind of glass. At United Builders we recommend dual-pane replacement windows.

The two most common kinds of window glass are single-pane and dual-pane. The main difference between the two is the number of glass layers. Single-pane glass only has one layer of glass, while dual-pane has two. This difference in layers is crucial for the function of your replacement windows.

Energy Loss

Most window experts can agree that about 70% of energy loss occurs through windows and doors, and 90% of window energy loss occurs through the glass. In other words, when your house is getting cold during a chilly Southern California night, or hot during a warm sunny day, it’s most likely because your window glass isn’t doing a good job at insulating your home.


Since dual-pane replacement window has two layers of glass, it’s automatically better at insulating than single-pane glass. Dual-pane windows’ layers are also separated by a space of air or gas that increases insulation even more. This is because gas, like the Argon used by Anlin window systems, is dense than air. The higher density makes it harder for energy to get through, making the window more impervious to outside temperatures.

Reduce Energy Usage

Dual-pane windows can help reduce your home’s energy usage by up to 24% in the winter months and up to 18% in the summer months. That’s a lot of savings, and that’s not even all the benefits that dual-pane glass offers. Dual-pane windows can also benefit your home with noise reduction. The two layers of glass and Argon gas between them not only stop temperature fluctuations but also noise. This works both ways, keeping the traffic or lawn mower sounds out of your living room, and your crying baby’s screams out of your neighbor’s backyard.

It is important to note that dual-pane windows cost more than single-pane. However, your long-term energy savings will be noticeable, and will eventually help you recoup your initial window replacement investment. It’s also vital to be aware that you won’t get the most out of these benefits from energy savings and noise reduction, unless you replace ALL the windows in your home. Replacing just one or two old windows won’t have the same effect as replacing all of them.
