How Much Home Insulation Do You Need?

Home Insulation Installation

Home insulation is a vital part of controlling your dwelling’s internal temperature. The right amount of insulation in your attic, walls, and crawl space forms a barrier between the inside of your home and the outside. In summer, that means cooler temperatures inside and your air conditioning works more efficiently. During the winter, insulation keeps chilly Ohio winters at bay. Valley Insulation discusses how much home insulation you need.

R-Values in Cincinnati

Standards for R-values in home insulation vary depending on where the insulation goes. The Insulation Institute recommends homeowners insulate their attics with R-values of R-38 to R-60. Floor insulation should be R-25 to R-30, and walls should be R-13 to R-21 in Cincinnati. Higher R-values for attic insulation occur for two reasons. First, warm air easily escapes through the attic as it rises in your home. Second, installers can readily add more insulation in between attic joists. 

Thickness

The thickness for home insulation in the Greater Cincinnati region depends on where the insulation is going. Loose-fill insulation varies anywhere between 13 to 18 inches deep in an attic. Wall insulation depends on the thickness of wall cavities, which typically are 3-¼ to 3-½ inches thick. Joists in a crawl space that hold up your home’s floors are anywhere from 9 to 11 inches deep.  

Understanding R-Value

R-value measures the efficiency of insulation for every inch of material. Nu-Wool blow-in insulation has an R-value of 3.8 per inch, which translates to an R-value of 13.3 for walls. Crawl space insulation can amount to R-values of 35 to 41. Cellulose insulation such as Nu-Wool works wonderfully in an attic, where R-values can range from 50 to almost 70. How much home insulation we put in your attic depends on how much insulation you already have and how much weight your ceilings can hold. 

Adding It All Up

The most important measure of how much home insulation you need comes down to overall efficiency. This happens by preventing air temperature swings between the inside and outside of your home. Over time, you save more money on your utility bills by reducing how much your air conditioning and heating runs. The longer you own your home, the more money you save with the right amount of home insulation.
