The information on this page, and the publications available from CIMA should help you decide for yourself which insulation approach is right for your project. When you choose insulation for a new or existing home you will find many alternative products available. You must sort through confusing and conflicting claims to find the right insulation material. When you know all the facts, however, you'll find that one insulation material stands out from the rest. 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.
