Energy efficiency is a big deal across the world. The National Fenestration Rating Council has designed energy performance label guides for homeowners and contractors so they can search out the perfect window for window replacement projects. Since climates are different in various parts of the U.S., the labels vary as well. Those who live in Chino, CA need different windows than those who live in the Midwest. You need to know what the labels mean if you are going to make the right decisions for your window replacement in your home. Here are some guidelines to follow.</br>
<br>Energy Performance Ratings</br>
<br>The U-factor is an important rating to watch when looking into window replacement. The rate of heat loss from a building is indicated in the U-factor and the ratings usually fall between 0.20 to 1.20. The lower the value, the greater the window’s resistance to heat flow and the better it insulates your home. The insulating value of the window is the R-value, which is inverse of the U-value. The higher the R-value, the better.</br>
<br>You will also want to pay attention to the solar heat gain coefficient, or the SHGC. This number indicates how well a window blocks heat from the sun. The fraction of solar radiation that is admitted and absorbed in the window and then released inward is expressed as a number between 0 and 1. The lower the number, the better. A low SHGC means the window transmits very little solar heat.</br>
<br>The U-factor and the SHGC are the most important numbers in a window replacement project. However, there are many others that can help you gain access to understanding on the windows as well.</br>
<br>Visible transmittance is the property that shows how much visible light is transmitted through the window. The higher the VT (which lies between 0 and 1), the more light is transmitted.</br>
<br>Air leakage is shown through cubic feet of air passing through a square foot of window space. Heat loss and gain can infiltrate through cracks in the window assembly. The lower this number is, the less air will leak through the cracks.</br>
<br>And condensation resistance measures the ability of the window to resist condensation on the interior surfaces. The higher the rating, the better it is at resisting condensation. The rating cannot predict condensation, but it can give a method of comparing products to each other. The number will lie between 0 and 100 in this case.</br>
