How Do Energy Efficient Windows Work?

Energy Efficient WindowsOne of the most popular reasons homeowners replace the windows in their homes is because of the improved energy efficiency that new windows can provide. With energy efficient windows installed in your home, you can reduce the workload of your HVAC system, which may lead to a reduction in your monthly energy bills. But, how do new windows better insulate your home?

Replacement windows, especially modern ones, contain a number of features to minimize heat loss. First, the glass itself will contain a Low-E (short for low emissivity) coating that reflects solar radiation. Some windows contain double and even triple panes of this Low-E glass to maximize the effect. Additionally, the window frame can include small chambers that trap warm air and create a barrier to heat transfer.

What Are the Best Energy Efficient Windows for Your Home?

Determining which energy efficient windows are best for your home all depends on the climate where you live. When shopping around, look for labels from the following two organizations:

  • National Fenestration Rating Council
  • Energy Star

These two organizations work together to give ratings to each window, which you can reference against the weather patterns in your area to determine which are the most appropriate. For instance, the U-factor illustrates the strength of the window’s insulation, and the solar heat gain coefficient (SHGC) measures the amount of solar radiation the window allows to pass through. If you live in a cold climate, you’ll want better insulation and more solar radiation. If you live in a warm climate, less insulation and solar radiation will likely be better for your home.
