LEVELROCK RH® is a gypsum underlayment engineered for rapid installation over hot water tubes or electric heating cables. It acts as the thermal mass for any infloor radiant system. LEVELROCK RH encapsulates the tubes or cables in crack resistant, noncombustible gypsum. This unique system resists breakdown to 150ºF (66ºC). And because it's poured only 3/4" above the tubes or cables typically 1 1/2" thick, the heating system is more responsive and more comfortable.
Also offered in a "Green" formulation for LEED points, LEVELROCK is an ideal solution for sustainable building projects.
