Understanding R-Value:
Insulation is specified by its thermal resistance or R-value. "R" means resistance to heat flow. The higher the R-value, the greater the insulating power. The amount of insulation you need depends mainly on climate, type of heating (gas, oil, electricity) you use, and the area of the house you plan to insulate. The U.S. Dept. of Energy has established minimum recommended insulation R-values for six distinct parts of the country, or insulation zones.
