R-Value and Insulation

R-value is a measure of an insulating material’s ability to resist heat flow. The higher the R-value, the better the insulating power. According to the U.S. Department of Energy, the R-value of loose-fill fiberglass insulation is 2.2 to 2.7 per inch. The total R-value of blown-in insulation once installed will depend on the overall depth and density of the layers of insulation.

The depth to which your fiberglass insulation should be installed depends on the climate where you live. In colder climates, more layers of insulation should be used in order to result in a higher overall R-value. This is to combat the phenomenon known as convection, which typically occurs in attics in cold weather. As the warm air from a heated home rises, it can infiltrate into the cold attic. The cold air then sinks into the house, making it harder for the HVAC system to maintain a comfortable temperature inside.

One of the most important factors in obtaining a high R-value of your insulation is how it is installed. In order to get the maximum R-value, it is important to hire professionals to install a quality fiberglass insulation. That’s why you should work with BELDON® to get energy efficient insulation for your home. We install Owens Corning Expanding Blown-In PINK® Fiberglas™ insulation, which has been specifically designed to anticipate the phenomenon of convection. Plus, our knowledgeable technicians will use a specialized machine that maximizes the material’s insulating power.
