A more energy efficient home starts with proper insulation. Here’s what you need to know about insulating your home.
Insulation & R-Value
Insulation effectiveness is measured in R-value.
The higher the R-value, the more effective the insulation.
Certain areas in your home need a higher R-value than others.
Roof Slope Cavity
Spray foam applied to an R-value of R49 or greater keeps heat from escaping the attic in the winter and entering in the summer.
Insulation to at least R60 using spray foam and cellulose keeps temperatures in living spaces below more stable.
Spray foam or blown-in cellulose applied to an R-value of at least R20 further stabilizes indoor temperatures.
Batt, blown-in, or sprayed insulation in these areas provides soundproofing between rooms.
The area between floors is a crucial area to insulate and should be applied to an R-Value of at least R30.
Basement or Crawl Space
Water resistant insulation with an R-value of R15 and drainage help control temperatures and humidity.
