One of the most common and effective installations of infloor radiant heating is with Therma-Floor, commonly known as a gypcrete. The gypsum underlayment is designed to pour over hot water tubes or electric heating cables, acting as the thermal mass for any radiant floor system. Therma-Floor systems can be used in many different situations, because it can be installed on top of subfloors and concrete slabs, whether existing or new.
Manufactured by Maxxon Corp., Therma-Floor encases the tubes or cables in crack resistant, noncombustible gypsum. Its special formula resists breakdown up to 150ºF (66ºC). And because it’s poured only 1-1/4″ (32 mm) thick, the heating system is more responsive and more comfortable. As a “green” building material, Therma-Floor is an ideal solution for sustainable building projects.
