Schlüter®-BEKOTEC

Application and Function

Schlüter®-BEKOTEC is a modular screed system for crack free and functionally safe floating screeds and heated screeds with coverings made of ceramic tiles, natural stone or other materials.

The system is based on the studded polystyrene screed panel, Schlüter®- BEKOTEC-EN, which is directly installed on top of load bearing substrates or conventional heat insulation and/or sound insulation panels. The geometry of the Schlüter®-BEKOTEC-EN studded panel results in a minimum screed thickness of 32 mm between the studs and 8 mm above the studs. The studs form a grid pattern with a distance of 75 mm between them to accept the 16 mm diameter heating pipes if a heated screed is to be installed. The floor heating system is easily adjustable and ideally suited for use with low temperatures, since the screed volume to be heated or cooled is relatively small (approx. 57 kg/m2 or 28.5 l/m2 with 8 mm coverage).

The curing stresses that occur in the screed due to shrinkage are absorbed by the studded pattern, thus controlling deformations such as curling over the entire area. It is therefore unnecessary to install movement joints or control joints in the screed. As soon as the cement screed is ready to support weight, the uncoupling mat Schlüter®- DITRA 25 (alternatively: Schlüter®-DITRADRAIN 4 or Schlüter®-DITRA-HEAT) can be installed (calcium sulfate screed ≤ 2 CM-%).
Ceramic tiles or natural stone tiles are then installed directly over this layer, using the thin-bed method. Movement joints in the covering layer are created using Schlüter®-DILEX according to industry guidelines.

Cover materials that are not susceptible to cracking, such as parquet or carpeting, can be directly installed over the screed as soon as it reaches the necessary residual moisture level for the corresponding covering.


Schlüter®-BEKOTEC

Installation

  1. Schlüter®-BEKOTEC-EN is installed over an even and sufficiently load bearing substrate. Larger uneven sections should be levelled with screed or suitable fill materials prior to installation. If required, install additional suitable insulation materials on the substrate, observing the applicable regulations for sound and/or heat insulation. If cables or pipes are installed on the load bearing substrate, install a full layer of sound insulation in accordance with DIN 18560-2 above the levelling layer. Observe the maximum compressibility CP4 (≤ 4 mm) when selecting a suitable insulation material. If the construction height does not allow for using polystyrene or mineral fibre insulation, the Schlüter®-BEKOTEC-BTS sound insulation membrane with a thickness of just 5 mm can achieve a significant improvement in sound insulation. 
  2. The 8 mm thick perimeter strip, Schlüter®-BEKOTEC-BRS 810, is placed at the perimeter, where the covering meets wall or fixtures. The foil leg integrated into the edge strip must be positioned between the substrate (or the top insulation layer) and the studded panel. If a flowing screed is to be applied, the Schlüter®-BEKOTEC-BRS 808KF with adhesive leg is used. The edging strip is attached to the wall using the adhesive strip on the reverse side. Placing the screed panel onto the self adhesive foam leg prevents back flow of the screed. 
  3. The Schlüter®-BEKOTEC-EN modular screed panels must be cut to size in the peripheral areas. Use of the special edge board, Schlüter®-BEKOTEC-ENR 1520P (see page 4), simplifies cutting and minimises waste. The Schlüter®BEKOTEC panels are equipped with a mortise and tenon type edge design for interconnection.
  4. To create a Schlüter®-BEKOTECTHERM comfort floor, the system pipes with a diameter of 16 mm are now clamped between the cut back studs. The spacing of the pipes must be determined on the basis of the required heating output, as shown in the Schlüter®-BEKOTEC heating diagrams. 
  5. As part of the screed installation, fresh cement screed of quality CT-C25-F4, max. F5, or calcium sulfate screed CA-C25-F4, max. F5, is installed with a minimum screed cover of 8 mm over the studded panels. The screed thickness may be increased to max. 25 mm for levelling. Appropriate flowing screeds of type CAF/ CTF with the respective specification may also be used. Please refer to the systems approved for this application. Note: Please contact our Technical Department unit to discuss different screed properties for specific building projects in advance. To avoid sound transmission between individual rooms, the screed should be separated in these places, using the expansion joint profile Schlüter-DILEX-DFP.
  6. As soon as the cement screed is ready to support weight, the uncoupling mat Schlüter®-DITRA 25 (alternatively: Schlüter®-DITRA-DRAIN 4 or Schlüter®DITRA-HEAT) can be adhered, observing the installation instructions of product data sheet 6.1 (alternatively: 6.2 or 6.4). Gypsum based screeds may be covered as soon as they have reached a residual moisture content of < 2 CM %. 
  7. Ceramic tile or natural stone can be directly installed on top of the uncoupling mat, using the thin bed method. The ceramic covering must be divided into fields with movement joints above the uncoupling mat in accordance with the applicable regulations. We recommend the movement joint profiles Schlüter®DILEX-BWB / -BWS / -KS / -AKWS for creating movement joints (see also product data sheets 4.6, 4.7, 4.8 and 4.18). 
  8. Our corner movement profiles Schlüter®DILEX-EK or Schlüter®-DILEX-RF (see product data sheet 4.14) can be used as a flexible edge joint in floor to wall transition areas. The protruding sections of the Schlüter®-BEKOTEC-BRS edging strip should first be trimmed.  
  9. The Schlüter®-BEKOTEC-THERM ceramic thermal comfort floor is ready for heating just seven days after the completion of the cover assembly. Increase the supply temperature by a maximum of 5 °C a day to reach the desired operating temperature, starting from 25 °C water temperature. 2 9.1 Schlüter®-BEKOTEC 
  10. Covering materials that are not susceptible to cracking (e.g., parquet, carpeting or synthetic coverings) are directly installed over the BEKOTEC screed without the uncoupling mat. The height of the screed must be adjusted to the corresponding material thickness. In addition to the applicable installation guidelines, note the permissible residual moisture level of the screed for the selected covering material.

Benefits of the Schlüter®-BEKOTEC System

Warranty:
Schlüter-Systems offers a five year warranty for the life of the cover assembly, provided all installation instructions were observed and the covering is used as intended.

Crack free covering:
The Schlüter®-BEKOTEC system is designed to reduce shearing tensions in the screed within the grid of the studded panel. No construction reinforcement is required.

Non buckling construction:
The cover assembly of the Schlüter®- BEKOTEC system is free of inherent stresses. Consequently, buckling in the system is virtually impossible. This is especially applicable in the presence of temperature fluctuations; e.g. with heated screeds.

Joint free screed:
The regular patterns of the Schlüter®- BEKOTEC studded panel evenly reduce tensions in the screed, which allows for constructing the screed without movement joints.

Movement joints in the joint pattern of the tile or stone covering:
With the Schlüter®-BEKOTEC system, the design of movement joints can match the joint pattern of the tile or stone covering, since it is not necessary to continue construction joints from the screed into the surface covering. The applicable regulations for the placement and construction of movement joints in and around the tile field must be observed.

Short construction time:
As soon as the screed produced with the Schlüter®-BEKOTEC system is able to support weight, coverings of ceramic tile, natural stone or artificial stone can be directly installed on top of the Schlüter®- DITRA 25 membrane. Ceramic thermal comfort floors are ready for heating only seven days after the completion of the cover assembly.

Low construction height:
Compared to conventional heated screeds according to DIN 18 560-2, the Schlüter®-BEKOTEC system saves 37 mm in construction height.

Material savings:
Only 57 kg/m2 ≙ 28.5 l/m2 of screed are required with a screed cover of 8 mm. This advantage is reflected in the static calculation.

Fast reacting heated floor assembly:
Compared to conventional heated screeds, cover assemblies installed with a Schlüter®-BEKOTEC-THERM ceramic thermal comfort floor react much faster to temperature changes, since the volume to be heated or cooled is much lower. Consequently, the heated floor system is particularly suitable for operation at low temperatures.
