If you have been looking into insulating your home or business, then you have probably come across the term “R-value”. R-value is an important factor when it comes to insulation. Understanding the R-value of an insulation material will tell you about it’s effectiveness, as well as help you to decide how much of it you need.
So, what is R-Value? R-value measures how well certain insulation materials can resist heat transfer. The higher the R-value, the greater the insulation’s performance. Here in Northern Illinois, the recommended R-value for attic insulation is between R49 and R60, because we are in the cold climate zone. This is equal to about 14 to 19 inches of loose fill cellulose insulation. So even if there is some insulation in your attic, it is very possible that it is not enough for our climate.
Factors used to determine an R-value include the material’s thickness, density, and type. Adding additional insulation in your home increases the R-value and the resistance to heat flow. If you’re planning to use more than one layer of insulation, then you would add the R-values together to determine their total effectiveness. To choose the best insulation for your home from the many types of insulation on the market, you’ll need to know where insulation is needed, and what R-value you want to achieve.
