Cellulose Insulation Calculator

Use the appropriate calculation tool below depending on the type of application to determine how many bags of thermal insulating cellulose you will need to perform your insulation work.


Attic

ft²

This calculation indicates the minimum number of bags to use. The final result will vary according to the application technique, the equipment and the hose used. The thermal resistances presented in this chart are measured after settlement, according to ASTM C518 standard and ASTM C687 conditioning method. A 15% settlement rate for RSI 8,6 (R-49) and RSI 8,8 (R-50) and a 20% settlement rate for RSI 10,8 (R-61) was added.

Floor/Ceiling

ft²
in
lb/ft³

This calculation indicates the minimum number of bags to use. The final result will vary according to the application technique, the equipment and the hose used. The minimum number of bags required takes into account the volume of the wood structure. For floors/ceilings with metal structure, additional bags may be required. Check with your representative for more information.

Wall

ft²
in
lb/ft³

This chart indicates the minimum number of bags to use. The final result will vary according to the application technique, the equipment and the hose used. The minimum number of bags required takes into account the volume of the wood structure. For walls with metal structure, additional bags may be required. Check with your representative for more information.
