Loose fill cellulose insulation r value.

Metric r2 6 per 100 mm. 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. There are other factors to consider. 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. Imperial r3 8 per inch which is about the same as or slightly better than glass wool or rock wool. The higher the r value the greater the insulating power. Click the button to calculate the approximate r value for this job.

Loose fill fiberglass by comparison provides an r value of 2 2 to 2 7 per square inch. Achieving the desired r value depends on both the depth of the insulation and its density. Loose fill fiberglass by comparison provides an r value of 2 2 to 2 7 per square inch. In laboratory testing the average r rating for cellulose insulation is between 3 2 and 3 8 per 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. The thermal conductivity of loose fill cellulose is approximately 40 mw m k r value. R means resistance to heat flow. As a loose fill insulation cellulose provides high insulating values represented by its higher r value and it creates a good barrier against air leaks and infiltration.

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. Compare insulation r values before you buy. This doesn t represent the whole picture of thermal performance. The r value of loose fill cellulose is r 3 2 to 3 8 per inch2.

Insulation depth depending on your climate energy codes require varying r values for ceiling insulation. This is higher than other common loose fill insulation such as fiberglass which averages. This calculator is to be used as an estimating tool only.
