Find your zone on the map and then use the above insulation r value chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces. The higher the r value of the underlayment the less heat will be able to move through it while the lower the r value is the less insulation the underlayment provides.

R value is a measure of insulation s ability to resist heat traveling through it. For radiant floor heating you want the total r value to be as low as possible lower than 4 0. F see r value definition at definitions of r k u values for some building materials such as sheet flooring we give an r value for a specfic thickness other than the standard 1. The higher the r value the better the thermal performance of the insulation.
