R-Value
FTC R-VALUE STATEMENT:
R-Value is the
measurement of resistance to heat flow. The higher the R-value, the
greater the insulating power. Compare insulation R-values before
you buy. 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. To get the marked R-value, it is essential
that this insulation be installed properly.
