Windows are the Achilles’ heel of a home that isn’t properly insulated. That’s because old, inefficient, or leaking windows will cause a considerable amount of cooled or heated air to escape from your home. By switching from old single pane windows to double pane windows, you can increase your home’s energy efficiency—as well as the money in your pocket from utility bills savings!
What are Double Pane Windows?
Double pane windows are made from two panes of glass separated by a spacer that holds trapped gas, such as argon or krypton. The spacer helps hold the panes of glass firmly in place even if they’re subjected to pressure. A seal keeps the gas from leaking out from between the two layers, ensuring that the windows will perform at impressive levels.
The Benefits of Double Pane Windows
Lower Condensation Issues
If you’ve owned a house with single pane windows in a cold climate, you know all about winter condensation issues. This is when water accumulates on your windows due to the temperature difference between the house’s interior and exterior. Single pane windows also transfer the cold into your home. As the cold infiltrates, all the water vapor in your home that comes into contact with it turns to water and then freezes from the low temperatures coming through your windows. Double pane windows solve this issue by separating the warm interior pane and the outer colder pane. Find out about double pane window repair for fogged windows here.
Because double pane windows keep the cold out in the winter and retain heat in the summer, they are more effective insulators than single pane windows. The increased insulation comes from the extra layer of glass, of course. But even moreso, the gas or air that’s trapped between the two layers does the brunt of the insulating by slowing the transfer of heat in either direction of the window.
Blocks the Noise
If you live in a noisy neighborhood, you’ll enjoy the noticeable increase of quiet you get after upgrading to double pane windows. Compared to single pane windows, they barely let any sound in at all.
Why Choose a Special Gas Filler?
Some double pane windows have air between the layers. Though air helps effectively insulate the window, a dense gas like argon or krypton will provide even better insulating properties for the windows. Argon is the best gas to use because it’s colorless, odorless, and nontoxic. Even if the glass leaks for some reason, it won’t cause any harm in your home.
Pay Attention to Spacers
Most people give them very little thought, but the spacers between the two layers of glass in the window make a difference in thermal performance. Look for “warm edge spacers” which function as insulators and prevent heat from moving from one pane to the other.
Are they Worth the Investment?
If you have single pane windows and high energy bills, double pane windows are worth the investment if you upgrade all of them. Keeping even a couple of single pane windows, however, will limit any savings you’ll see. When you change out all the windows at once, you form an effective barrier that will make the most difference.
By upgrading to double pane windows, you’ll be making a significant improvement in your home’s insulation with cost-efficient and long-lasting benefits. Best of all, your home will be more comfortable year round, which makes it an invaluable investment.
