Schluter DITRA HEAT DUO Matting is polyethylene membrane with a cut-back stud structure and a special sound-deadening/thermal barrier fleece laminated on the underside. It is a universal substrate for tile coverings, which serves as an uncoupling, crack bridging, waterproofing, vapour pressure equalization layer and is designed to be used as a carrying membrane for the Schluter DITRA HEAT E HK Heating Cable.
Available in either 10 metre rolls (10m length x 1m width), single 1m² units (multiple 1m² units will be supplied as a single roll) or single 0.8m² mats (0.8m x 1m).
This membrane is also available with a self-adhesive fleece backing for easier and faster installation – the Schluter DITRA HEAT DUO PS Self Adhesive Matting.
Schluter DITRA HEAT DUO Matting can be used on both walls and floors. The Schluter DITRA HEAT E HK Heating Cable snaps easily into place in the matting without the need for fasteners or clips. The heating cable can be installed wherever it is necessary in the matting, meaning you can put heating cables only under the areas that you want to heat – creating a cost efficient and effective under tile heating installation.
Schluter DITRA HEAT DUO Matting 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 adhesive and the covering materials used in conjunction with Schluter DITRA HEAT DUO Matting must be suitable for the corresponding application and meet the applicable requirements. We recommend using a 6mm notch trowel when installing, such as the Schluter TROWEL.
If installing covering materials that are sensitive to moisture (e.g. natural stone or synthetic resin panels) or in the case of moisture underneath the covering (e.g. from fresh screeds), it is recommended to trowel the sealing adhesive Schluter KERDI COLL L over the abutting joints of the matting and to cover the joints with the 12.5 cm wide seaming tape Schluter KERDI KEBA.
Schluter DITRA HEAT DUO Matting features a special thermal fleece laminated to the underside which bonds with the adhesive, while also reducing impact sound and enabling a faster heat-up response for the tiled covering. The fleece results in a sound improvement of 13dB. The thermal barrier results in approx. 80% more heat directed to the tiled surface compared to the standard DITRA HEAT E Matting.
