· In accordance with the chart below, you must Install the minimum number of bags ~
per 1,000 sq ft of net area for each R-Value listed
· The maximum net coverage must not exceed that specified for each R-Value
· The Installed insulation must be at or above the specified minimum thickness for
each R-Value
· Failure to Install the required minimum weight per sq ft of insulation at or above
the minimum thlck-ness will result In reduced R-Value
· ThiS product should not be mixed with other blown insulations or the thermal
claims will become invalid

R-values are determined In accordance with ASTM C 687 and 518
Compiles with ASTM C 764 as Type 1 insulation
"R" means resistance to heat flow The higher the R-Valuel the greater the
insulating power To get the marked R-Value, It IS essential that the
insulation IS Installed properly

READ THIS BEFORE YOU BUY
What you should know about R-Values
The chart shows the R-Value of this Insulation R means 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
