If you have old-style, single-pane windows in your home, the chances are pretty good that you’re spending more money to heat and cool your home than you would if you upgraded to modern energy-efficient windows. In fact, the opportunity to enjoy beautiful new windows and lower utility bills is the primary reason that many homeowners seek energy-efficient windows. However, there’s also the satisfaction of knowing that you’re doing your part to conserve precious natural resources and preserve a healthy environment. To make it easy for homeowners to identify energy-efficient windows, the U.S. government and the window industry teamed up to create the ENERGY STAR® certification program. Replacement windows that meet the standards set by this program qualify as ENERGY STAR® windows, and that’s a handy way for homeowners to evaluate whether they’re truly investing in a home upgrade that will help them reduce their energy consumption.
Understanding the Components of Energy-Efficient Windows
Although looking for the ENERGY STAR® label is one way to identify energy-efficient windows, if you’re interested in maximizing the thermal performance of replacement windows, it can be helpful to know what features to look for. At Johnson County Siding & Window Co., we’ve been using our industry expertise to help homeowners in the Kansas City metro area choose high-performing energy-efficient windows for many years. A few of the features we typically point out are:
Energy-efficient windows typically have at least two glass panes with inert gas filling the space between them. This type of construction blocks heat transfer far better than a single-pane window can. Some windows are available with triple-pane glass, which will increase their energy efficiency even more.
Low-Emissivity Glass Coating
Commonly referred to as Low-E, this coating can block up to 90% of the sun’s rays from entering your home through your windows. The more layers of this coating there are, the more energy efficient your windows are likely to be.
The most energy-efficient windows will have premium-grade spacers crafted from silicone foam or stainless steel. A window’s spacer system is important because it maintains the proper distance between panes and helps preserve the window seal, thus minimizing air infiltration.
Depending on the type of replacement windows you’re considering, you may find additional features aimed at enhancing energy efficiency, including triple weather stripping and foam insulation.
