Homeowners interested in making their houses more energy efficient are asking the question: What is a double glazed glass pane and how does it help with energy costs? Since windows can be the cause of major energy loss throughout the year, the right windows can make a significant difference in your heating and cooling bills.
Understanding Double Glazed Glass Panes
A double glazed window is made from two panes of glass that are separated from each other by a spacer bar. The two panes are then sealed to create an area of contained air within the pane that acts as an insulator for the home’s interior. A number of additional features can be added to increase the insulating properties of the double-glazed panes, such as inert gas inside the two panes or low-energy coatings on the glass.
How Does Double Glazing Save Money?
Double glazed windowpanes help to reduce the amount of temperature-controlled air that is lost through heat transfer. The pocket of air acts as an insulation material to reduce energy loss.
How Much Can You Expect To Save?
Energy experts estimate that replacing your old windows with double paned glass windows can reduce your energy costs by as much as 50 percent. These energy efficient windows reduce the amount of heat and cold air lost through conduction of air from the inside to the outside surfaces of the window, keeping indoor temperatures more comfortable and reducing the amount of wear on your system to maintain temperatures, according to the Department of Energy.
Old windows on your home can cost you hundreds of dollars each year in additional energy costs. Replacing them with more energy efficient double glazed glass panes can reduce energy loss and maximize the efficiency of your heating and cooling system.
