Schlüter-BEKOTEC-THERM is a safe, low-height, underfloor heating assembly. In conjunction with offering underfloor heating with control technology, the modular system is an energy efficient and quick reacting radiant heated floor system with especially low supply temperatures. The system is based on the studded screed panel, Schlüter-BEKOTEC-EN, which is directly installed on top of a load bearing substrate and/or conventional heat and sound insulation panels.
The studs are spaced in such a way that the Schlüter heating pipes can be installed at regular intervals to suit the room requirements; the studs are spaced at intervals of 75 mm. Screed mortar CT-C25-F4 (ZE 20) or CA-C25-F4 (AE 20) (maximum flexural strength F5) covers the studs and the heating pipes by a minimum of 8 mm and maximum of 25 mm. This results in a screed thickness of at least 32 mm between the studs.
The contraction that occurs when the screed cures is reduced within the pattern of the studs, so that no tension can build as a consequence of contraction buckling. It is therefore not necessary to divide the screed into separate fields with movement joints. Upright structural elements need to be secured with edging strips and construction joints will be carried over into the floor assembly.
Once the screed is ready to support weight, the Schlüter-DITRA uncoupling mat is installed. Ceramic tiles or natural stone can be installed directly on top of this layer in thin-bed tile adhesive. Movement joints in the cover layer above Schlüter-DITRA should be established with Schlüter-DILEX in the usual spacing. Since the screed mass to be heated or cooled is comparatively small, the radiant heated floor is easily regulated and can be operated with low supply temperatures.
The electronic Schlüter control components, which are also available in wireless versions and are coordinated with the system, also allow for the quick and accurate control of the Schlüter-BEKOTEC-THERM ceramic thermal comfort floor. The modular structure of the entire Schlüter control technology allows for simple installation and operation.
A wide range of requirements are placed on heated floor constructions
- Heat and sound insulation
- Absorption and distribution of traffic loads
- Waterproofing in wet rooms
- Utilisation area and design
- Large area heating
In addition to ceramic tile and natural stone, other coverings such as parquet, laminates, and carpet can also be used, following the applicable installation standards.
With Schlüter-BEKOTEC-THERM we have managed to achieve a balance of the varied requirements placed on heated floors. The modular system allows for simple, effective, and building wide co-ordination and installation.
