Amvic’s Ampex hydronic radiant panel combines rigid insulation, a vapor barrier and a PEX tubing locking mechanism into a single solution for both residential and commercial applications, the company states. A four-sided interlocking shiplap connector system makes for a quick, easy and secure panel installation, and mushroom nub technology allows for easy walk-in pipe installation, Amvic adds.
