Double pane windows are an eco-friendly alternative to traditional single pane windows. They are becoming more common in today's homes and offices because of their ability to save energy, reduce noise pollution, and absorb UV radiation. Although their cost is higher than traditional windows, the energy savings over the long run more than makes up for it.
What are double pane windows? They are windows made up of two panes of glass with inert gas pumped between them, which creates an insulating layer. The space between the two panes is generally 1/2 to 3/4 inch, and is most often filled with argon, carbon dioxide, or krypton. Additionally, the glass is often coated with a reflective layer, which reflects heat. Double pane windows have become more common over the past twenty years, and there are even options for triple or quadruple paned windows.
By using double pane windows over single pane windows, it is estimated that one will save 25% on electricity in the winters by reducing heating bills and 18% in the summers by using less air conditioning. This is because in the winter, the window allows sunlight in but provides an insulating barrier to the cold. For the reflective coating to be most beneficial in hotter climates, you want the coating to be on the outside surface of the inner glass. This will reflect away the sun in the summer months. For more Northern, cold climates, the coating should be on the inside, to keep the heat in.
One can expect to pay a considerable amount more for double pan windows, especially considering one must replace all of their windows in order to receive the maximum benefit. However, the energy savings will add up over the years, making it a wise investment. By using less energy to heat your home, you are also minimizing your eco-footprint and making a positive environmental step.
