How to Use Cellulose Insulation

Cellulose insulation is a loose, blown-in insulation product that is easy-to-apply in open attics, wall cavities using dense pack or netting or an added adhesive, and in mid-floor applications. Cellulose insulation can be utilized in both residential and commercial construction, and certain cellulose insulation products are designed for different construction types.

Cellulose Insulation R-Values

Cellulose insulation is a blown-in insulation product that has a flexible R-value. The R-value is determined by the depth of material installed by the contractor. The more depth, the higher the R-value. (R-value requirements are governed by the Authority Having Jurisdiction (AHJ) in each state or municipality. Please check with your AHJ to determine the correct code for your area.)

Different regions require different levels of insulation.This map shows the most cost-effective levels of insulation for the different climate zones in the U.S. Based on your zone, use the table to find out how much insulation you need. The higher the R-value of insulation, the more thermal insulating capacity it has. Zones 1, 2, and 3 make up the southern portions of the U.S. and have an average suggested minimum insulation rating of R-30 in attics and R-13 along floors. Zones 4 to 7, which cover the northern half of the country, suggest that attic insulation have a minimum R-38 rating and floor insulation have a minimum R-25 rating.
