What Makes a Window Energy-Efficient

Windows can be a major source of heat loss and gain, and this can have a significant impact on your energy costs. However, today’s windows are far more energy efficient that those produced even 10 or so years ago, which means that installing new energy efficient windows is one of the easiest ways to reduce your environmental impact and lower your energy bills.

Still, you may be wondering just what it is that makes these newer windows so superior? Luckily, this immediately becomes clear as soon as you look at the overall design of these windows.

High-Quality Insulated Frame

The overall quality of the frame construction and the materials used are both important in determining how energy efficient the window will be. You can easily find Energy Star-rated windows with aluminum, fiberglass, wood, vinyl and composite frames, each of which is designed is a slightly different way to improve its insulating ability. For instance, fiberglass and vinyl frames are often filled with foam insulation.

The improved insulation helps to prevent air leakage, which is a major source of heat loss in the winter and heat gain in the summer. Weather-stripping around the window also helps to prevent air leaks. However, it is important that the window is installed properly to actually gain these benefits.

Two or More Panes of Glass

Many old windows featured only a single pane of glass, which dramatically reduced their insulating ability. Modern windows generally feature two panes of glass separated by a small pocket of air that allows for better insulation. Some manufacturers go a step further and fill this cavity with krypton, argon or other gasses, as these are an even better insulator than air.

At Peach Building Products, we also offer a range of windows with three or more panes of glass. These windows are not only that much better insulating and thus more energy efficient, but they also provide improved resistance to impact and breaking to make your home more secure.

Reflective Glass Coating

Many energy efficient windows also feature a special coating or glazing over both the interior and exterior panes. Referred to as a low-emissivity (or Low-E) coating, this glazing helps the glass to refract infrared light. By refracting sunlight, the coating helps to prevent it from heating up the house during the summer. As well, any interior light is also refracted back into the home, which helps to prevent heat from escaping during the winter.

In addition, this coating can also help to protect your furniture, floors, walls and other décor from fading or being damaged by sunlight. This is because the Low-E coating helps to block out harmful ultraviolet rays in addition to standard infrared light.

Improving the energy efficiency of your home is something every homeowner really needs to strongly consider. Not only will it help you reduce your energy bills, but it will also ensure that you do your part to reduce your environmental impact. Luckily, having new energy efficient windows installed isn’t all that difficult and doesn’t have to be that expensive.
