The R-value is a way of comparing the insulating properties of different materials. The U.S. Department of Energy recommends unfinished attics have an R-value of R-30 for hot climates, R-38 for temperate climates and R-49 for cold climates. Loose fill cellulose insulation typically offers an R-value of 3.7 per inch; loose fill fiberglass, 2.5 per inch; loose fill mineral wool, 2.8 per inch; and fiberglass blanket insulation, 3.2 per inch.

The Department of Energy states that a properly insulated attic can save a typical homeowner 10 to 50 percent of her energy bill. Signs that a home may need more insulation include drafts, temperature variation between rooms, a ceiling that is cold in winter or warm in summer, excessively high energy bills and ice damming on the roof and eaves in winter. A homeowner can contact a professional energy auditor to assess the situation. After receiving an assessment, a homeowner may want to contact her local utility company, since many offer financial incentives for insulation projects.
