Schluter^®-DITRA-HEAT

Schluter® DITRA-HEAT suma una función personalizable y cómoda de calefacción eléctrica del piso a las funciones de DITRA: desacoplamiento, impermeabilización, control del vapor y soporte para asegurar una instalación duradera.

Calefacción del piso

DITRA-HEAT combina la flexibilidad de los cables calefactores sueltos con la facilidad de instalación de los sistemas de membranas. Los cables pueden ubicarse donde sea que se desea calefaccionar, sin crear diferencias de altura en el piso. No se requiere el uso de componentes autoniveladores para encapsular los cables, lo que reduce el tiempo y el esfuerzo de instalación.

Desacoplamiento

Las baldosas llevan años instalándose de manera exitosa mediante la incorporación una membrana de desacoplamiento, o interfaz resistente al cizallamiento, en el conjunto de baldosas. DITRA-HEAT brinda desacoplamiento por medio de su configuración geométrica, la que permite un movimiento de los planos que neutraliza de manera efectiva el movimiento de tensión diferencial entre el substrato y las baldosas, eliminando así la causa principal de rotura y astillamiento de la superficie revestida.

Waterproofing

DITRA-HEAT provides reliable waterproofing. Its polypropylene composition protects the substrate from moisture penetration, which is particularly important in today’s building environment where most substrates are moisture-sensitive.

Vapor Management

The free space on the underside of DITRA-HEAT provides a route for excess moisture and vapor to escape from the substrate that could otherwise cause damage to the tile covering above. Thus, DITRA-HEAT effectively manages moisture beneath the tile covering.

Support/load distribution

When placed on a solid foundation, columns or pillars can support tremendous loads. The same physical principle applies to DITRA-HEAT installations. Column-like mortar structures are formed in and between the studs on the surface of the matting. Loads are transferred from the tile covering through these column-like mortar structures to the substrate. Since DITRA-HEAT is virtually incompressible within the tile assembly, the advantages of uncoupling are achieved without sacrificing point load distribution capabilities.

Alternate Floor Coverings over DITRA-HEAT

DITRA-HEAT is suitable for applications with engineered wood, vinyl, wood plastic composite (WPC), luxury vinyl tiles (LVT), luxury vinyl planks (LVP), stone plastic composite (SPC) tiles and planks, and laminate flooring. See the Alternate Floor Coverings over DITRA-HEAT Technical Bulletin for more information, including requirements and limitations.

DITRA-HEAT and DITRA-HEAT-DUO membranes do not require any special maintenance.

All substrates must be clean, even, and load bearing. Bond inhibiting surfaces must be removed prior to the application of DITRA-HEAT. For complete installation guidelines and warranty criteria, please refer to the downloadable Schluter®-DITRA-HEAT Installation Handbook or to the installation video online.

Note: Type, thickness, and format of the tile or stone surface covering must be suitable for the intended application. Minimum tile format is 2" x 2" (5 cm x 5 cm).

Applications with tile formats less than 2” x 2” (5 cm x 5 cm) require special considerations, please contact Schluter-Systems Technical Services Representatives at 800-472-4588 (USA) or 800-667-8746 (Canada) for more information regarding installation requirements and warranty eligibility.

1. Using a thin-set mortar that is suitable for the substrate, apply the thin-set mortar (mixed to a fairly fluid consistency, but still able to hold a notch) using a 1/4" x 1/4" (6 mm x 6 mm) square-notched trowel.

2. Apply DITRA-HEAT to the floor, fleece side down. Solidly embed the matting into the mortar using a float, screed trowel, or DITRA-ROLLER, making sure to observe the open time of the bonding mortar. If the mortar skins over prior to matting installation, remove and reapply. Note: It may be helpful to back roll the end of the matting before installation, or place boxes of tile on top of the matting after installation, to avoid curling.

*When using the DITRA-ROLLER, place a weight (e.g., bags of mortar/grout or box of tile) not to exceed 75 lbs on the DITRA-ROLLER shelf. Slowly move the roller from one end of the matting to the other, slightly overlapping successive passes.

3. Lift up a corner of the matting to check coverage. Proper installation results in full contact between the fleece webbing and the thin-set mortar. Note: Coverage may vary with mortar consistency, angle at which the trowel is held, substrate flatness, etc. If full coverage is not achieved, remove and reapply, making sure to verify proper mortar consistency and application.

4. Abut end and side sections of adjacent sheets. Note: Aligning the studs on the top of the matting during installation can help make subsequent heating cable installation easier.

5. The DITRA-HEAT-E-HK heating cables can now be installed. Installation instructions are covered under the DITRA-HEAT-E-HK product page.
Note: Tile can be installed directly over the DITRA-HEAT membrane immediately after the Schluter®-DITRA-HEAT-E-HK cables have been installed using an unmodified thin set.
