With so much focus on energy-efficient replacement windows nowadays, the National Fenestration Rating Council (NFRC) has designed an energy-performance label to help homeowners and contractors more easily choose windows that will meet their needs. Because climates in different regions of the United States vary so widely, looking at this NFRC label can help ensure that your new windows will perform . . .

The Condensation Resistance Factor (CRF) is a measurement established by the American Architectural Manufacturers Association (AAMA) that identifies how well a window resists the formation of condensation on the inside surface of the glass. The National Fenestration Rating Council (NFRC) has a similar measurement simply called Condensation Resistance (CR), however, there are some differences in how these two values are . . .

One of the major performance rating categories that is usually (but not always) listed on an NFRC label is Air Leakage. This measurement is sometimes referred to as “air infiltration” and measures the amount of exterior air that will pass through a window and into a home. In general, most air infiltration happens through gaps and cracks in the outside . . .

One of the major performance rating categories listed on an NFRC label is Visible Transmittance (VT). This category measures how well a window is designed to let daylight into a home. The rating score for visible transmittance ranges from zero to one, and most homeowners look for a higher number because this means that their homes will get more natural . . .

One of the major performance rating categories listed on an NFRC label is the Solar Heat Gain Coefficient (SHGC). This measurement is also sometimes called Passive Solar Gain (PSG). The SHGC measures the amount of solar radiation (heat from the sun) that a window allows through the glass. While a U-Factor measures the amount of heat that passes from inside . . .

One of the major performance rating categories listed on an NFRC label is the U-Factor, which is also sometimes called the U-Value. This category measures the rate of heat transfer from the inside of a home to the outside. While the scientific measurements that go into calculating a U-Factor can be rather complex, all that a homeowner really needs to . . .

This is a question that gets asked a lot by homeowners in Baltimore, Maryland, and surrounding areas. However, in order to provide a precise answer, we need to get more specific with the question. There are a few different factors to consider when determining the energy efficiency of a window, such as frame material, window style, and window brand. Let’s . . .

If you’re like many homeowners in the Nashville, Tennessee, area, you hear all the time about how having new windows installed is such a great investment to make because it will increase your home’s energy efficiency. But what does this really mean? How exactly will new windows help you conserve energy? Let’s examine some of the most important features and . . .

If any of the windows on your Atlanta, Georgia, residence have been underperforming, you may be considering having replacement windows installed. However, such a situation begs the question: Should you only replace the windows that are giving you the most trouble? Or should you take this opportunity to replace all of the windows on your home at once? How Many . . .

If you’ve ever lived in a home with underperforming windows, then you probably know how much windows can affect your everyday life. From keeping cold air out during the winter to retaining all that nice air-conditioned air in the summer, your windows play a huge role in regulating your home’s comfort level. However, comfort isn’t the only thing that your . . .
