Foam Insulation & R-value
What is R-value?
We keep talking about this R-value when it comes to home insulation, but you may not know what it is. Here's a simple explanation:
The "R" in R-value stands for "resistance"; resistance in the movement in temperature through your walls and ceilings. When you buy insulation, you are buying "R-value". Therefore, the higher the R-value, the better the insulation.

Your Home May not Have Enough R-value
Most homes in the United States are not well insulated. In fact, according to the U.S. Department of Energy, only 20 percent of the houses built before 1980 are considered well insulated. Incredibly, many homes have no insulation at all, due to the fact that building codes didn't require insulation prior to the mid-1970's.
