In the Chicagoland area you need to have between R-49 and R-60. Realistically, you should be at R-49 or higher. We recommend R60 because insulation will settle over time.

If you live in an older home, you should have more insulation because it is likely not air sealed the same way a newer home is.

The right type of insulation to use really depends on how each home is built. If you have dropped ceilings, we can often use spray foam insulation. However in other cases blown insulation works best. Fiberglass is recommended in basements wall below ground level. 

Let our insulation experts talk to you about your home and what would be best for you.

Attic insulation cost is between $1.90 and $2.50 per sq. ft for R49- R60 Cellulose or Fiberglass.  . Close cell foam insulation price will range from $3.50 per sq. ft. for R21 to $7 per sq. ft. for R49.

Price will vary depending on the type of insulation we use, sq. ft. of the house and roof or wall structure.
