![]() ![]() Various performance ratings – like U-factor and Solar Heat Gain Coefficient – measure a product’s effectiveness in insulating and blocking heat from the sun, among other things. How do I know if a window or a door is energy efficient?Ĭertification programs such as those administered by the National Fenestration Rating Council (NFRC) and ENERGY STAR provide ratings designed to indicate a window or door’s efficiency. Choosing energy-efficient windows makes your home more comfortable, as their performance determines how much heat comes in and escapes out through the windows. Replacing windows with energy-efficient ones can help reduce your utility bills, but the benefits go much further. What’s the first thing I need to know when it comes to windows and energy efficiency? In winter, the heat will be reflected back into your home whereas, in summer, it will be reflected away to keep your home cooler.I need new windows. LoĒ-180 glass also helps improve the efficiency of your windows by reflecting heat. The harder your heating system has to work, the more it will cost you on a daily, weekly, and monthly basis. Leaky windows or windows with poor U-Factors will allow the heat inside your home to escape. High U-Factor windows will then do their job and help maintain the lowest possible temperatures in your home.ĭuring the winter, you want to keep your home comfortably warm without making your heating system work overtime. After a few minutes, or once the air in your home is well circulated, you should close all of your windows and keep them shut throughout the day. While some might be tempted to air their home throughout a hot day in the middle of summer (in an effort to make the most of a nice breeze), it’s best to air your home in the morning while the air is crisp and at its coolest. Instead of allowing the hot summer air to sneak in, they keep the heat outside where it belongs. The right windows can make a great difference in the comfort level of your home. The Benefits Of Quality Windows In The SummerĮven if you don’t use any kind of cooling system during the summer, you will still feel the benefits of quality windows. For those who are in the market for energy efficient windows, you should look for double-pane windows with a U-Factor of 0.30 or less, or a triple-pane window with a U-Factor of about 0.15. The window frame and spacers also need to be inspected and put to the test as part of their U-Factor evaluation. High-quality, specialized window coatings can also help improve the rating as well as the type of gas used to fill the spaces between the window panes. Triple-pane windows will have a higher rating than double-pane ones, for obvious reasons. It’s not just about the window glass itself and the type of glazing but also the other parts of the window. ![]() When measuring the U-Factor of a window, there are several parts that need to be considered. This means that investing in a quality window will pay off in the long run since you’ll spend that much less money keeping your home warm in winter and cool in summer. Lower U-Factors reflect a greater level of insulation and a higher level of energy efficiency. The U-Factor or U-Value measures the rate at which heat is lost through a particular surface or substance. ![]() It’s also good to note that a U-Factor of 0.25 equals an R-Value of 4. The U-Factor, on the other hand, is used to determine the energy efficiency of windows. The R-Value is normally used for rating walls, roofs, and floors. Both are relevant to the thermal resistance of various elements of your home’s structure. When you consider the insulation of your home, two terms are particularly relevant the R-Value and U-Value. ![]()
