R-values of Carpet Pads. r value

Share:


What is the best type of carpet pad to use with EFH?

For TZ under the pad:

Lower the r-value the better.  3/8" to 1/2", 6-8 pound density.


For EV OVER the pad:

Higher the r-value the better.  3/8" to 1/2", 6-8 pound density.


See attached sheet with common r-values of flooring materials.
