Loose Fill Cellulose Insulation R Value

Compare insulation r values before you buy.

Loose fill cellulose insulation r value. R means resistance to heat flow. The higher the r value the greater the insulating power. 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. 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.

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 higher than other common loose fill insulation such as fiberglass which averages.

This doesn t represent the whole picture of thermal performance. This calculator is to be used as an estimating tool only. 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.

Imperial r3 8 per inch which is about the same as or slightly better than glass wool or rock wool. 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.
