It's the insulation you will want in your home. Cellulose insulates better. It not only offers more heat transfer resistance per inch than other fiber insulation materials, it also seals the home against air infiltration better than other fiber insulations. Cellulose insulation productively recycles a waste product that presents communities with a serious disposal problem. Cellulose insulation makes homes safer by slowing the spread of fire.
Cellulose insulation makes efficient use of natural resources.
At R 3.6 to 3.8 per inch cellulose insulation is considerably better than most mineral fiber blowing wools, but R-value is only one factor in the energy efficiency of a home. One reason for this is the capacity of cellulose to stop air infiltration. The fibers of cellulose insulation are much finer than mineral fiber blowing wool. When cellulose is pneumatically installed it takes on almost liquid-like properties that let it flow into cavities and around obstructions to completely fill walls and seal every crack and seam. No fiber glass or rock wool material duplicates this action.
