What Is R-Value and Why Is It Important?

Posted on on April 9th, 2015


Did you know that many older homes have little or no insulation?  According to the U.S. Department of Energy, 80% of homes built before 1980 are not considered well insulated.


If you have an older home, it might be time to consider improving your home insulation to reduce your energy bills and improve the comfort of your home.  This measurement of energy-efficiency is called “R-Value.”


What is R-Value?


R-Value is a measure of how well your home insulation keeps your home cool in the summer and warm in the winter.  The higher the R-Value, the better job your insulation does at preventing heat from passing through your walls and ceilings.  The graph above depicts the effectiveness of each type of insulation and how well it prevents heat from entering your home during the summer, and and leaving your home in the winter.


Spray foam insulation has the highest R-Value.  It is a great option for open areas, including your home attic, walls, basement, and crawl spaces.  Tripolymer injection foam insulation also has a high R-Value.  Injection foam insulation can be applied to existing wall cavities from the exterior of your home.  This helps fill more of your wall cavity, providing protection against the outside elements and keeping healthy, conditioned air indoors.
