Cellulose vs. Fiberglass:
Why Cellulose Insulation is Superior.
Do you really care how well your insulation works at 70 to 75 degrees Farenheit? At 70 to 75 F blown fiberglass is at its best, but as shown in the graph to the right, blown Fiberglass falls behind Cellulose at every other tested temperature. Cellulose Insulation is the insulation that works well when you need it - through winter's cold and the summer's heat.
Insulating power, there when you need it. Fiberglass loses insulating power when air temperatures get colder - as much as 41%. Cellulose increases insulating power when air temperatures get colder - as much as 12.7%. When air temperatures get warmer, rising from 70 to 90ºF, fiberglass loses 21% of its R-Value, while cellulose loses only 3 1/2%.
