Schluter®-DITRA-HEAT-E-HK are twisted pair heating cables designed for integration with the DITRA-HEAT uncoupling membrane in interior floor warming applications.
All substrates must be clean, even, and load bearing. Bond inhibiting surfaces must be removed prior to the application of DITRA-HEAT. For complete installation guidelines and warranty criteria, please refer to the downloadable Schluter®-DITRA-HEAT Installation Handbook or to the installation video online.
Note: Type, thickness, and format of the tile or stone surface covering must be suitable for the intended application. Minimum tile format is 2" x 2" (5 cm x 5 cm).
