Schluter-DITRA-HEAT-DUO-S is a polypropylene membrane -universal tile substrate that reduces impact sound and ensures a quicker heat up response. It is waterproof and resistant to chemical stresses, and can be used to create a certified bonded waterproofing assembly.

• It is a universal substrate for tile coverings, which means that it can be used on both floors and walls.
• It reduces impact sound, which can be a problem in areas with heavy foot traffic.
• It ensures a quicker heat up response, which can be beneficial in cold climates.
• It is waterproof and resistant to chemical stresses, which makes it a durable and long-lasting product.
• It can be used to create a certified bonded waterproofing assembly, which is a requirement for some applications.

In floor areas, the heating cables can be installed immediately after adhering DITRA-HEAT-DUO, 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-DUO in accordance with the applicable standards, using the thin-bed method. The thin-bed tile adhesive bonds with the cutback stud structure of the DITRA-HEAT-DUO membrane.
