(The thermal resistance factor measure the insulation's ability to resist cold or heat from the outside environment and keep the temperature even indoors.) In addition to being more fire resistant, cellulose averages a higher thermal resistance factor than either fiberglas or rockwool. According to Merril Warnick, corporate secretary for Intermountain Industrial Insulation, thermal resistance factors in cellulose average Under pressure from cellulose manufacturers, and faced with shortages of the other two types of insulation, the utility is reevaluating the policy which bans insulation contractors using cellulose from participating in the program. IN has. in 20 months, netted the 16 participating contractors about $2 million. 3.7 per square inch, while fiberglas average 2.2 and Since the IN program requires a resistance of 19 and the price per pound is similar in all three materials, cellulose is actually the cheapest insulator, Warnick says.
