Schluter DITRA HEAT DUO PS - 10m² Uncoupling Membrane & Underfloor Heating Mat

Properties

Application

• Underfloor heating cable installation: Designed for the attachment of heating cables, the system is intended to be installed as a secondary heat source to provide added comfort for tile and stone surface.
• Interior floor installation substrate: Exclusively intended for installation on floors in interior areas, it is a universal substrate for tile coverings, which serves as an uncoupling, crack bridging, waterproofing and vapour pressure equalisation layer. Substrates must be flat, clean, dust free, dry, smooth, rigid and load bearing, with no deflection. The tile covering is installed directly over DITRA-HEAT-DUO-PS in accordance with the applicable regulations, using the thin-bed method. The cementitious tile adhesive bonds with the cut back stud structure of the DITRA-HEAT-DUO-PS membrane.
• Sound insulation & quick heat up: DITRA-HEAT-DUO-PS includes a special 2mm fleece covered in pressure sensitive adhesive laminated to the underside, which, in addition to bonding with the substrate, reduces impact sound and causes a faster heat-up response.
• Pressure sensitive adhesive: To install, peel the release film off and place the membrane on the substrate. It can be lifted and re-positioned providing no pressure has been applied to it. However once pressure has been applied the adhesive sticks the membrane firmly to the substrate. The heating cables can be installed immediately after adhering the membrane, using a spacing of 9 cm (every third stud ≙ 136 W/m²).

Both polypropylene and the adhesive layer are not UV-stable in the long term; the product should not be stored or processed in places with prolonged exposure to direct sunlight. With dry storage at temperatures above freezing (5-30 degrees C), DITRA- HEAT-DUO-PS should be installed within 18 months of manufacture. It is best to install DITRA-HEAT-DUO-PS at ambient temperatures of 5-30 degrees C.
