Loose Fill Cellulose Insulation R Value

Metric r2 6 per 100 mm.

Loose fill cellulose insulation r value.

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. In laboratory testing the average r rating for cellulose insulation is between 3 2 and 3 8 per inch. The r value of loose fill cellulose is r 3 2 to 3 8 per inch2. 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.

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. With loose fill cellulose insulation you can achieve an r value of 3 2 to 3 8 per square inch.

The thermal conductivity of loose fill cellulose is approximately 40 mw m k r value.

The higher the r value the greater the insulating power. Insulation depth depending on your climate energy codes require varying r values for ceiling insulation. Loose fill fiberglass by comparison provides an r value of 2 2 to 2 7 per square inch. R means resistance to heat flow.

There are other factors to consider. This is higher than other common loose fill insulation such as fiberglass which averages. When walls are already finished injecting loose fill cellulose insulation is one of the few ways of adding insulation. Loose fill fiberglass has an r value of r 2 2 to 2 7 per inch3.

Loose fill fiberglass by comparison provides an r value of 2 2 to 2 7 per square inch. Compare insulation r values before you buy. Imperial r3 8 per inch which is about the same as or slightly better than glass wool or rock wool. 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.

Achieving the desired r value depends on both the depth of the insulation and its density. This calculator is to be used as an estimating tool only. This doesn t represent the whole picture of thermal performance.
