What You Should Know About R-Values
R means resistance to heat ow. The higher the R-value, the greater the insulating power.
Compare insulation R-values before you buy. To get the marked R-value, it is essential that
this insulation be installed properly.
There are other factors to consider. The amount of insulation you need depends mainly on
the climate you live in. Also, your fuel savings from insulation will depend upon the climate,
the type and size of your house, the amount of insulation already in your house, and your
fuel use patterns and family size. If you buy too much insulation, it will cost you more than
what you’ll save on fuel.
