If you’re going to invest in Redmond replacement windows for your home, why not make sure every aspect of those windows is as good as can be? One important aspect is the window glass. You need to be sure you choose the right kind of glass for your replacement windows, and that might be double-pane.

The two most common kinds of window glass are single-pane and double-pane. The main difference between the two is the number of glass layers. Single-pane glass only has one layer of glass, while double-pane has two. This difference in layers is crucial for the function of 7yoru replacement windows.

Most window experts can agree that about 70% of energy loss occurs in 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 Tucson night, or hot during a warm desert day, its most likely because your window glass isn’t doing a good job at insulating your home.

Since double-pane window glass has two layers of glass, its automatically better at insulating than single-pane glass. Double-pane windows’ layers are also separated by a space of air of gas that increases insulation even more. This is because gas, like the commonly used Argon and Krypton, is dense than air. This higher density makes it harder for energy to get through, making the window glass more impervious to outside temperatures.

Double-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 saving, and that’s not even all the benefits that double-pane glass offers. Double-pane windows can also benefit your home with noise pollution reduction. The two layers of glass and gas not only stop temperature 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 double-pane windows cost more than single-pane. However, your long-term energy savings will be noticeable, and might even help you recoup your initial window glass investment. It’s also vital to be aware that you won’t see any of these benefits, from energy savings to 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.
