On average, you can save up to 20% on your home's heating and cooling costs or up to 10% on its total energy costs by adding insulation to attics, floors, crawl spaces, and accessible basement rim joists, and by reducing unwanted air leaks all around your house.

R-Value – Insulation is important because of its ability to reduce the amount of heat that flows between the inside and outside of your home. The ability of insulation material to reduce heat flow is called its R-value. The greater the R-value, the more this heat flow is reduced.

Cost of Insulation –  Insulation costs depend on R-value and type of material, and costs vary greatly at the retail level. The table below contains very general averages. Prices for loose- fill and spray foam are based on professional installation and reflect both material and labor costs. Check with a local supplier and/or contractor for actual costs.
