Yes newer windows are more efficient. It’s important because, according to the US Department of Energy, heating and cooling a home represents 54% of your energy bill. Windows are a weak area in your homes insulation and can be responsible for 25-50% of a home’s energy loss. Over time that can add up to a substantial amount. Consumers have demanded better windows and manufacturers have made them.
Unlike older windows, new energy efficient windows have multiple panes of glass with a pocket of air or gas trapped in between the panes. Argon is the most frequently used gas. It, like all the gasses used in windows, is non-toxic, colorless, and odorless. A gas layer is important because it slows down the transfer of energy through the window just like a layer of insulation does to your walls. Double pane windows have become the standard but if you want even better performance you can get triple pane windows. The more panes and more dense the gas used the better your performance. A side benefit to this gas layer is it tends to reduce sound transfer as well.
Another element to a better energy performing window is using specially formulated coatings on the glass. Low E glass has a layer of transparent metallic oxide applied during it’s manufacture. This layer reflects infrared and ultraviolet (UV) light. This helps to keep heat in in the winter and out in the summer. A side benefit to keeping the UV light out is it protects your home from these damaging rays.
