This Is Loose-Fill Cellulose Insulation
Pneumatic Application Chart |
The manufacturer recommends that the insulation be installed at these minimum thicknesses, maximum coverages, and minimum weights per square foot to provide the levels of insulation thermal resistance (R-value) shown. The following coverages are based on settled density of 2.4pounds per cubic foot and nominal bag weight of 30 pounds. Actual coverage may vary on application technique. |
| R-Value Mean. Temp | Minimum Thickness | Maximum Net Coverage (No allowance for joists) | Minimum Weight per Square Foot | |
| To obtain a heat flow resistance of: | Installed insulation should not be less than : | Maximum Square Feet Per Bag | Bags per 100 Square Feet | The weight per sq. ft. of insulation should be not less than |

READ THIS BEFORE YOU BUYWhat 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 save on fuel. To get the marked R-value, it is essential that this insulation be installed properly. |
