The type of insulation you need depends on where it will be installed, what R-values are required and your budget. Where you live also affects which insulation you choose. For example, a home in Arizona will have different minimum R-value requirements than one in Minnesota.
Almost any type of insulation can be used to insulate a wall. If cavity insulation is installedâfor example, fiberglass batts, sprayed fiberglass, cellulose, or spray polyurethane foamâthe maximum R-value Measure of resistance to heat flow; the higher the R-value, the lower the heat loss.nder no circumstances should fiberglass batts be used to insulate basement walls. Because fiberglass batts are air-permeable, they are unable to prevent moist interior air from contacting colder basement walls. That's why fiberglass-insulated basement walls can easily become damp and moldy.
