Why Buy Energy Star Windows

Brought to you by Armorvue Home Exterior of Cleveland

The key to saving energy is not to waste it in the first place, and that’s especially true when it comes to windows. We all know that old windows can be drafty and cold. That’s because the materials they are made of degrade over time and just don’t seal like they used to. Plus, the construction materials and techniques used years ago just aren’t as energy efficient as they are today. The solution, of course, is to remove the old windows and install new energy-efficient ones, and this is where Energy Star comes into play.


ENERGY STAR is a program run by the U.S. Environmental Protection Agency and U.S. Department of Energy that promotes energy efficiency.  ENERGY STAR Certified Products meet three criteria: they are manufactured by an ENERGY STAR partner; they are certified by the National Fenestration Council (NFRC); they meet strict EPA energy efficiency guidelines.

What are the direct advantages of using ENERGY STAR windows?

Studies have shown that installing ENERGY STAR certified windows and skylights can shrink energy bills – and carbon footprints – by an average of 12% nationwide, compared to non-certified products. For typical homes, this can result in significant savings.

How are ENERGY STAR windows constructed?

Superior frame and sash materials – Companies use a variety of framing materials today when making energy-efficient windows. Especially popular are vinyl windows with low maintenance vinyl frames. These are typically made with thick vinyl walls with multiple air chambers to improve thermal performance. Wooden windows are also available and provide excellent thermal insulation values; they are a good choice for homes that have historical features.
Low-E glass – Low-E refers to a special coating applied to panes of glass. By reflecting infrared light, Low-E helps stop temperature transference. In addition to its energy-saving properties, Low-E glass helps reflect UV rays too that lead to fading color on interior furnishings.
Multiple panes – Glass itself is not a very good insulator. Older windows with only one pane of glass allow heated or cooled air to escape more rapidly. Two panes of glass insulate much better than a single pane because of the air space between the two panes. Triple pane adds another air pocket, enhancing the insulation value even more.
Gas Fills – The air between the glass panes works as an insulator because air is a poor conductor of heat. Some energy-efficient windows go one step further and have argon or krypton gas injected between the panes of glass. These gasses are heavier than air and provide even better insulation.

Do ENERGY STAR windows help with air-conditioning?

Rooms that have direct sunlight baking down on the windows during the summer can get pretty hot. That’s because a standard single-pane window allows approximately 75 percent of the sun’s heat to cross over into your home. With ENERGY STAR windows this number is cut down significantly so the room is cooler and the load on your air conditioner is reduced. So, yes, ENERGY STAR certified windows help keep houses cooler.
