Carpet and pad may be installed over Ecowarm RadiantBoard. When installing the pad, care should be taken to avoid puncturing tubing. Optionally, if especially high point loads are anticipated on a floor it is advised that a thin layer of underlayment plywood be applied over Ecowarm RadiantBoard prior to carpet and pad installation to protect the very tough PEX radiant tubing. As with all radiant heating installations, a thin slab foam rubber pad should be used in all cases. If possible, a low R-value carpet is the best selection for best system performance. If carpet pad is glued, a high-temperature latex adhesive must be applied. Do not glue to the PEX radiant tubing! Maintain 2” minimum tubing clearance from carpet tack strips.
