Determining The R Value of Insulation

To calculate the correct R Value for your home insulation project you must consider a few factors including the coverage area, type of climate and heating system in the home. The R Value indicates an insulation's resistance to heat flow. The higher the R-value, the greater the overall insulating effectiveness.

R Values can vary depending on the location of the insulation, wheather it is compressed or not and there are even diffences between walls and ceiling R Values.

The department of energy has an online R Value calculator that determines the appropriate values based on zip code and area and insulation materials.

You can find this free online R Value calculator at Department of Energy R Value Calculator
