Blown in cellulose insulation is 2-3 times denser than fiberglass insulation. Studies comparing blown in cellulose insulation and fiberglass insulation show that cellulose insulation was 38% tighter and required 26% less energy. A Princeton University study shows, a group of homes with blown in cellulose insulation in the walls had an average of 24.5% reduction of air infiltration compared to fiberglass insulation, with only the walls insulated. A similar study, the Leominster MA Housing Project for the Elderly, found that a building with blown in cellulose insulation compared to a building with R-13 fiberglass batt insulation in the walls and R-38 fiberglass batt insulation in the ceiling, had 40% lower leakage.
Blown in cellulose insulation is treated for fire retardancy. If a fire occurs, the blown in cellulose insulation, combined with its fire retardants, can slow the fire from spreading and can create a “2-hour firewall”. Scientists at the National Research Council of Canada report that, blown in cellulose insulation increases fire resistance by 22%-55%. When Blown in Cellulose insulation does burn, it generally doesn’t emit toxic chemicals.
Another advantage of blown in insulation is that it easily flows around obstructions and penetrates odd shaped cavities and it easily conforms around wires, electrical boxes and pipes.
