A: The denser, thinner pads such as a slab rubber or waffle rubber pad, without clay fillers, are considered the best choice among pads for use with radiant floor heating systems.

The lighter, less dense pads, such as bonded urethane and prime urethane, are usually too high in R-value to be a good choice because they inhibit the heat from passing through the cushion into the room, reducing your system's efficiency. For example, Treadmor by Sponge Cushion is a quality pad that performs well with radiant heating.
