Loose fill cellulose insulation r value.

This calculator is to be used as an estimating tool only. Input depth of existing blown in insulation in inches. When walls are already finished injecting loose fill cellulose insulation is one of the few ways of adding insulation. However like other loose fill insulation it also has a tendency to settle over time reducing its r value and its ability to prevent air movement.

Loose fill fiberglass has an r value of r 2 2 to 2 7 per inch3. With loose fill cellulose insulation you can achieve an r value of 3 2 to 3 8 per square inch. Loose fill fiberglass by comparison provides an r value of 2 2 to 2 7 per square inch.

Loose fill cellulose is relatively inexpensive yet still has an r value of about 3 5 per inch of thickness compared to fiberglass r value between r3 to r4 per inch. Click the button to calculate the approximate r value for this job. For loose fill insulation each manufacturer must determine the r value of its product at settled density and create coverage charts showing the minimum settled thickness minimum weight per square foot and coverage area per bag for various total r values. R means resistance to heat flow.

The thermal conductivity of loose fill cellulose is approximately 40 mw m k r value. There are other factors to consider. The higher the r value the greater the insulating power. In laboratory testing the average r rating for cellulose insulation is between 3 2 and 3 8 per inch.

This doesn t represent the whole picture of thermal performance. Imperial r3 8 per inch which is about the same as or slightly better than glass wool or rock wool. This is r value loose fill cellulose insulation read this before you buy what you should know about r values the chart shows the r value of this insulation. Insulation depth depending on your climate energy codes require varying r values for ceiling insulation.

Achieving the desired r value depends on both the depth of the insulation and its density. The r value of loose fill cellulose is r 3 2 to 3 8 per inch2. This is higher than other common loose fill insulation such as fiberglass which averages.
