An insulation materials r-value refers to its ability to stop or slow down the transfer of heat. It is based on a laboratory measurement, called an r-factor. The r-factor, multiplied by the thickness of the material in inches, gives you the r-value of the insulation. Laboratory measurements, however, do not always accurately reflect conditions in the real world. Most insulation materials lose their effectiveness when crammed into a tight space between walls. In addition, temperature can also make a big difference, some insulations operate better in colder temperatures, while others work best in warmer environments. In addition, if a material is stretched too thin or installed improperly, the r-value could diminish.
Good insulation can make your home more energy efficient, or it can leak the valuable energy you spend to regulate the temperature of your home. Which insulation you choose is an important decision, but it is even more important to make sure you hire a reputable contractor to apply the insulation. Many homes have incorrectly-installed insulation that causes serious energy issues, and the owners can go years without realizing the problem. Your insulation can go a long way toward making your home greener and more energy efficient.
