The reliable Schlüter-BEKOTEC-EN 18 FTS covering assembly technology is a system for crack-free and functionally safe floating screeds and heated screeds, with coverings made of ceramics, natural stone and other covering materials.
This floating system is installed directly on load-bearing, weight-distributing substrates, such as concrete, as well on existing wooden ceiling structures. The suitability of the substrate for heating purposes has to verified (movement joints, edge strips, etc.). The system is based on the Schlüter-BEKOTEC-EN 18 FTS studded screed panel with integrated 5 mm sound insulation, which is installed directly on the load-bearing substrate. An impact sound improvement of 25 dB in accordance with DIN EN ISO 717-2 has been measured for the system. The actual improvement offered by the respective assembly depends on the local conditions (structural design) and can deviate from this value. Therefore the measured test values do not always apply for the situation at the respective construction site. Reliable values can only be obtained by making direct measurements on site, taking into account the respective actual structural design. The geometry of the BEKOTEC-EN 18 FTS studded panel dictates a minimum screed layer thickness of 26 mm between and 8 mm above the studs. The stud distances make it possible to clamp the heating pipes of the system, which have a 12 mm diameter, in a 50 mm grid to produce heated screed.
Since only a relatively small amount of screed has to be heated or cooled (with a coverage of 8 mm, approx. 52 kg/m² ≙ 26 l/m²), the floor heating system is easily adjustable and ideally suited for operation at low supply temperatures.
The curing stresses that occur in the screed due to shrinkage are absorbed by the studded pattern. Tensions resulting from deformations can therefore not affect the entire area, and it is not necessary to install movement joints in the screed. Once the cement screed is ready to support weight, the Schlüter-DITRA uncoupling mat (alternatively, Schlüter-DITRA-DRAIN 4 or Schlüter-DITRA-HEAT) can be installed (gypsum-based screed ≤ 2 CM %). Ceramic tiles or natural stone can then be installed directly over this layer, using the thin-bed method. Movement joints in the covering layer have to be created with Schlüter-DILEX according to industry standards.
Cover materials that are not susceptible to cracking, such as parquet or carpeting, are installed directly over the screed as soon as it reaches the corresponding residual moisture level.
