⚠️ Important DITRA HEAT Installation Points ⚠️
PLANNING ⚠️ DITRA-HEAT is not for exterior applications. ⚠️ DITRA-HEAT is not designed as primary heat source. For more information on using DITRA-HEAT as primary heat, click here . For access to the DITRA-HEAT Online Estimator, click here . Select DITRA-HEAT and DITRA-HEAT-DUO membrane according to the size of the area to be tiled. Use DUO for assemblies over concrete subfloors. Though not required, it is recommended as it will improve the performance of the floor by preventing the concrete for competing for the heat. The maximum level of thermal insulation under the subfloor to which DITRA-HEAT can be installed is R20 (or Rsi 3.5). For the applicable heating cable spacing for your application, see the Spacing Details section in the Warnings section (pages 20-21). For buffer zone planning see the Warnings section (page 20-21) under Spacing Details. When measuring the area to be heated, be sure to measure accurately. The heating cable CANNOT be cut to fit.
