Back when we didn’t know better – when electricity prices were also way more affordable – energy efficiency wasn’t much of an issue. Today, though, with higher electricity rates and a heightened awareness of the rapid depletion of the planet’s natural resources, homeowners are much more energy conscious.
Energy-efficient windows are practically de rigueur these days, with windows playing such a huge and important role in energy conservation. The heat that passes through a window can affect how hard the home’s heating and cooling systems need to work. During summer, solar heat passing through a window will make the home’s cooling system work at capacity, consuming more energy. In winter, heat inside the home can escape through the windows, making the home’s heating system work extra hard as well.
According to the U.S. Department of Energy, heat gain and loss makes up around 25% to 30% of the home’s energy usage. This is rather significant, especially if the home has a particularly high energy consumption.
Fortunately, modern windows provide a solution to this problem. Energy-efficient windows have the ability to drastically reduce the transfer of heat through the window glass and frame. The less heat that is transferred through the window, the less the environmental systems have to work. Moreover, it is easier to control the indoor environment, making it more comfortable inside.
How Energy-Efficient Window Glass Works
The secret lies in the glass panels. Energy-efficient windows usually have double-pane glass,making it difficult for heat to pass through. Aside from the additional pane, the small space between the panes is usually filled with argon gas that also helps prevent heat transfer. On top of that, each glass panel is coated with a special film, known as low-emissivity (Low-E) coating, that acts as an additional barrier against heat.
Over the long run, the energy savings of your energy-efficient windows will more than make up for their initial cost.
With the information provided in this three-part blog series, you should be able to choose the right type of window for your home, not just for curb appeal, but also for the right function and energy reduction as well. Make sure that you work with a trusted window replacement professional in your area for best results.
