Benefits of Energy Efficient Windows

Today and every day the sun rains down immense quantities of energy on the earth. In cooler climates and winter months, this energy can be quite beneficial, warming our homes and reducing our need for heating. However, for homes in warm summer months, unmanaged solar energy creates a thermal heating load that must be removed by air-conditioning.

The majority of this solar heat gain comes through your windows. The most effective way to manage the amount of solar heat gain that enters your home is to block it before it gets into the building. The best way to accomplish this is to simply install replacement windows that have a low solar heat gain coefficient (SHGC) rating.

The National Fenestration Rating Council (NFRC) has established a standard method for rating the amount of solar heat gain that is admitted through a replacement window. This rating is readily available for all energy efficient windows and should be a major consideration in choosing a replacement window company. This method rates a replacement window from 0 (the least amount of SHG) to 1 (the maximum amount of SHG). The smaller the SHG number the better.

Our Cardinal LOE3-366 window units have an incredible solar heat gain of .21. Compare this energy rating with any replacement window product and you will discover what an incredible value our energy efficient windows provide. Dollar for dollar Jemison Window and Door sells and installs the most energy efficient windows in the marketplace.
