Maxxon® Gyp-Crete® Radiant is a gypsum underlayment designed to pour over hydronic tubes or electric heating cables, which then acts as the thermal mass for radiant floor systems. Encasing the tubes or cables in crack-resistant, non-combustible gypsum, the special formula resists breakdown to 150 °F (66 °C). Poured at just 11/4"" (32 mm) thick, Maxxon Gyp-Crete Radiant stabilizes your heating system, creating a more comfortable home/environment. Some radiant systems installed under plywood subfloors result in lost heat, as plywood is nearly four times more insulative than Maxxon Gyp-Crete Radiant.

Maxxon Gyp-Crete Radiant works above the subfloor for greater efficiency and consistent comfort.
