An energy-efficient window is a must for any green home. Having an idea on what makes a window energy-efficient can help you make an informed purchase. Better View Windows and More, one of the top roofing contractors in the state, lists them below.
The number of window panes can affect a window’s energy-efficiency. Glass is a poor insulator, so a single-pane window would be a poor choice for an energy-efficient window.
As a rule of thumb, when shopping for an energy-efficient window, look for double-paned windows. The pocket of air between the two glass panes slows down the transfer of heat, improving your window’s insulation capabilities. If you want higher energy-efficiency, does this mean that you should look for windows with a higher number of panes? The short answer is no.
Triple-pane windows are slightly more energy-efficient than double-pane windows, but they cost a lot more. As such, it makes more financial sense to buy a double-pane window. With a double-pane window, you can get roughly the same energy-efficiency at a lower cost.
To get a better idea on a window’s energy-efficiency, check a window’s thermal conductivity. The higher the frame material’s thermal conductivity, the less energy-efficient it is.
Total Window Performance
Keep in mind that a higher number of green features doesn’t necessarily make a window more energy-efficient. Instead of focusing on the features, focus on total window performance or how these features interact with each other to promote energy-efficiency.
The same rule applies to designing a green home. The various energy-efficient features of your home, including your windows, siding, roof and doors, have to work in conjunction to minimize power consumption.
Of course, you won’t be able to enjoy all the benefits of an energy-efficient window if it isn’t installed properly. That’s why you should only hire a qualified contractor.
