What Makes Energy Star® Windows More Efficient

We have all heard about the need to minimize our carbon footprint by reducing energy consumption. Energy Star® windows and doors are a great way to help keep heat out in the summer and heat in come winter. But how do these technologically innovative panes of frame glass really improve efficiency over a standard window?

Energy Star® Standards

First off, in order for a window to be considered Energy Star®, it must undergo rigorous testing by the National Fenestration Rating Council (NFRC), an independent organization that certifies and verifies all Energy Star products. Each product is required to meet incredibly strict standards with regards to its energy efficiency as dictated by the Environment Protection Agency (EPA).

Energy Star® Rated Materials

Energy Star® windows, regardless of the partnered manufacturer and the technology they use in their product, they all have similar efficiency features that are pretty much ubiquitous under the Energy Star® label. All Energy Star® windows are fabricated with the highest quality framing materials varying from fiberglass, to wood, to aluminum. These premium grade materials are built to be incredibly durable and designed to require as little maintenance as possible. The glass in an Energy Star® window is designed to have low-emissivity, filtering out some of the damaging ultra-violet radiation that enters your home daily. These low-emissive panes can reduce fading damage in your home by up to 75%. This drastically improves the lifespan of any furniture, painted walls, and flooring exposed to natural sunlight from the windows.

Energy Star® Performance

Energy Star® windows are designed to meet the specific needs of a specific climate and should be selected accordingly. Most common Energy Star® windows are comprised of two panes of glass with an inert, colorless, odorless, non-toxic gas such as Argon or Krypton that reduce heater transfer significantly better than air found between standard double-paned windows. Some windows under the Energy Star® label have three or more panes of glass providing optimal insulation value while still serving its main function as a window. Edge spacers on Energy Star® glass panes, especially the non-metallic kind, keep the glass panes at the proper distance from one another and minimize heat being transferred through the window.

Quality materials, advanced engineering/design, accompanied by the achievement of passing the highest efficiency standards, translates to a more energy-efficient home when equipped with the best windows in the industry. Consider Energy Star®, the benchmark for superior energy efficiency, when searching for ways to reduce your environmental impact, utility bill and preserve your home.
