Summer is in full swing. As the temperature rises, so too does the air conditioning bill. But with some smart window covering management, you can save on energy costs and cool your home.

According to Energy.gov, “about 30% of a home’s heating energy is lost through windows. In cooling seasons, about 76% of sunlight that falls on standard double-pane windows enters to become heat.” [1] The type of window covering will play a huge role in determining how much energy you can ultimately save. Here are a few examples:

Drapes or Curtains

The material, color, and backing material on your curtains or drapes will affect the amount of heat allowed to enter into your home. “Studies demonstrate that medium-colored draperies with white-plastic backings can reduce heat gains by 33%.” [1]


Window blinds can be especially effective at reflecting the sun’s heat. The type and color of your blinds, like with your drapes and curtains, will ultimately determine effectiveness. You also have the added benefit of extra flexibility by adjusting the slats to allow for more or less light. “When completely closed, highly reflective blinds can reduce heat gain by around 45 percent.” [2]

Window Films

Another way to block the heat is with window films. Window films adhere directly to the glass and can block ultraviolet (UV) radiation without obstructing your view. [1] Window films come with different performance ratings. You can check window film ratings by visiting the National Fenestration Rating Council (NFRC) website. [3]
