PRODUCT DESCRIPTION:
Maxxon's Therma-Floor^® is a gypsum underlayment designed to pour over hot water tubes or electric heating cables. It acts as the thermal mass for any radiant floor. Therma-Floor encases the tubes or cables in crack resistant, noncombustible gypsum. Its special formula resists breakdown to 150ºF (66ºC). And because it's poured only 1-1/4" (32 mm) thick, the heating system is more responsive and more comfortable.

THERMA-FLOOR® TECHNICAL DATA: Compressive Strength: Typical range of 2,000 to 3,000 psi (14 to 21 MPa) Specific Heat: .224 Btu/(lb · ºF) at 85ºF (.9385 kJ[kg · ºC] at 29.44ºC) Weight: At 1-1/4", less than 12 lbs./sq.ft. (At 32 mm, less than 58.7 kg/m²) Dry Density: 115 lbs./ft³ (1840 kg/m³) Point Loading: Typical loading of up to 2,500 pounds (1134 kg) on a 1" (25 mm) diameter disc Acoustical Performance: The acoustical performance of Therma-Floor is similar to Gyp-Crete Floor Underlayment. Contact Maxxon Corporation for reports. Coefficient of Conductivity (K): 4.96 Btu/(h­ · ft2 · °F) (.7142 W/[m · °C]) Thermal Resistance at 1-inch Thickness: R-0.208 Surface Burning Characteristics: Flame spread: 0 Fuel contributed: 0 Smoke density: 0 VOC: <24>3
