Schlüter®-DITRA-HEAT | Material | Schlüter-Systems



Schlüter®-DITRA-HEAT is a polypropylene membrane with a cut-back stud structure. A fleece fabric is laminated on the underside. The thickness of the membrane, including the stud structure, is approx. 5.5 mm or approx. 7.5 mm in the case of Schlüter®- DITRA-HEAT-DUO.

Polypropylene is not UV-stable in the long term; the product should not be stored in places with prolonged exposure to direct sunlight.

Material properties and areas of application:

Schlüter®-DITRA-HEAT is non-rotting, waterproof, elastic and crack-bridging. The material is highly resistant to solutions containing salts, acids and alkalis, as well as many organic solvents, alcohols and oils. The suitability of the material must be verified based on the specific chemical stresses, including the anticipated concentration, temperature and length of exposure. The water vapour diffusion seal of the material is relatively high. The material is physiologically safe. In special cases, the suitability of the material must be verified based on the anticipated chemical and mechanical stresses. The information provided below is intended as a general guideline.

Due to the special characteristics of the system, coverings installed over Schlüter®- DITRA-HEAT may have a certain hollow sound when they are walked upon with hard shoes or tapped with a hard object.

The use of Schlüter®-DITRA-HEAT in conjunction with heating cables for floor/wall heating is only approved for interior areas.
