Schlüter-DITRA-HEAT is a polypropylene membrane with a cut-back stud structure and an anchoring fleece laminated on the underside.
It is a universal substrate for tile coverings that forms an uncoupling, crack bridging, waterproofing and vapour pressure equalisation layer and can also be used to attach heating cables.
The substrate for the installation of DITRA-HEAT must be level and load-bearing. DITRA-HEAT is installed in a thin-bed tile adhesive that is suitable for the substrate, using a notched trowel (recommended size: 6 x 6 mm). The anchoring fleece on the underside of DITRA-HEAT is fully embedded and the fabric mechanically bonds with the adhesive. The curing time of the adhesive must be observed.
In floor areas, the heating cables can be installed immediately after adhering DITRA-HEAT, using a minimum spacing of 9 cm (every third stud ≙ 136 W/m²).
For wall installation, the heating cables are installed once an adequate adhesive bond has been reached. The installation spacing is either 6 cm (every second stud ≙ 200 W/m²) or 9 cm (every third stud ≙ 136 W/m²). The use of mats is recommended for wall areas.
The tile or stone covering is installed directly over DITRA-HEAT in accordance with the applicable standards, using the thin-bed method. The thin-bed tile adhesive bonds with the cut-back stud structure of the DITRA-HEAT membrane.
DITRA-HEAT is waterproof and resistant to any chemical stresses that typically occur in conjunction with tiled coverings. Where required, DITRA-HEAT can be used to create a certified bonded waterproofing assembly.
Use the cable tester Schlüter-DITRA-HEAT-E-CT to measure the resistance of the electrical heating cables DITRA-HEAT-E-HK and the remote sensors supplied with DITRA-HEAT-E thermostats. The testing device monitors the resistance of the heating cables during the entire installation phase and alerts the installer with an acoustic signal in the event of damage. The cable tester automatically shuts down 60 minutes after the last key activation (values will not be saved).
