Testing Existing R-Value

Does your existing insulation meet current standards? More Importantly does if function as intended? Performance is measured in R-Value. R-Value is a scale of heat retention. Often Insulation is improperly installed, leaving gaps and cracks for air to travel through. Lastly, air quality is an important test.

what is R-Value

R-value tells us how well insulation can resist heat flow.

R= Resistance to heat escape.

  • Attics is R-49/60 
  • Sidewalls R-21
  • Cantilevered Floors R-38
  • Transition Walls R-21
  • Basement Walls R-13
  • Crawlspace Walls R-21

Illinois current standards are moving closer to a 4.0 Air Exchange Rate and R-values consistent with optimal standards.

Illinois current standards for construction.  Choosing the right materials.

From mineral wool to radiant barriers, spray foam insulation, fiberglass insulation, foam board insulation, blown in cellulose insulation or some other less common form such as sheep’s wool, denim or others, each is measured in terms of its R-Value.

In Chicago, current standards are measured in R-Value ( the resistance to heat escape ) measured on a scale from 0-70 for all intended purposes of this example.

Current Insulation Standards

In the Chicagoland area you need to have between R-38 and R-60. Realistically, you should be at R-49 or higher.

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.

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

Attic insulation cost is between $1.50 and $3.50 per sq.ft. depending on the type of insulation we use, sq.ft. of the house and roof type.

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.
