SOPRA-CELLULOSE 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 m²
m²K/W

{{ results.numBags }} Estimated number of bags needed

RSI value {{ results.rsi }} m²·K/W

Applied thickness {{ results.thickness_applied }} in

Settled thickness {{ results.thickness_settled }} in

Mass per unit area {{ results.mass_per_unit }} lb/ft²

Coverage per bag {{ results.coverage_per_bag }} ft²

SOPRA-CELLULOSE technical data sheet does not have coverage recommendation for nominal insulation that exceeds R61 for attics,  and R75 for walls assembly. Therefore, any output from the calculator for situations that exceed those two limits are only given for guidance and do not represent a RESISTO Inc. prescription. This is explained by complex settlement behavior, namely, for high thickness applications.

For more support for applications which exceed the datasheet content, the customer shall contact a RESISTO Inc. representative.

The quantities indicated by the calculator are not a guarantee, express or implied, of the number of SOPRA-CELLULOSE bags needed for a specific project. RESISTO Inc. will not accept any liability whatsoever resulting from the use of the calculator, including the numbers of bags needed for the surface to be covered. Moreover, the number of bags required depends, in any situation, on the application technique, the equipment settings and the hose used, which is not under RESISTO Inc. control.
