Where you live different climates require different insulation r values.

Why higher r value in an attic.

The recommended level for most attics is to insulate to r 38 or about 10 to 14 inches depending on insulation type. An insulating material s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or r value the higher the r value the greater the insulating effectiveness. R value is a measure of insulation s ability to resist heat flow. There are many ways to retrofit a home with fiberglass and.

Achieving greater r values in exterior walls. R value is a measure of insulation s ability to resist heat traveling through it. Recommended home insulation r values. Insulation level are specified by r value.
