Schlüter®-BEKOTEC-EN 12 FK


For crack free and functionally safe floating screeds and heated screeds suitable with most floor finishes. Suitable for use with conventional cement screeds of strength class CT-C25-F4 (ZE 20) or calcium sulfate screed CA-C25-F4 (AE 20) as well as flowing screed.


A reliable covering assembly system. Installation is preferred by Schlüter-Systems trained installers

Features and benefits:

  • The floating system is installed directly on load-bearing, weight-distributing substrates such as concrete or existing wooden floor structures, using the thin-bed method.
  • The system is based on the studded polystyrene screed panel Schlüter-BEKOTEC-EN 12 FK with an anchoring fleece on the underside. The studded screed panel is directly installed onto suitable weight-distributing substrates as a bonded assembly, using the thin-bed method.
  • The studs have a cutback design to securely keep heating pipes in place without the need for clamps.
  • The studded panels are connected by overlapping a row of studs and clicking the panels together.
  • The curing stresses that occur in the screed due to shrinkage are absorbed by the studded pattern, thus controlling deformations such as curling. It is therefore unnecessary to install movement joints in the screed.
  • Schlüter-BEKOTEC-EN 12 FK is made of a high-impact polystyrene deep-drawn foil and is suitable for use with conventional cement screeds of strength class CT-C25-F4 (ZE 20) or calcium sulfate screed CA-C25-F4 (AE 20) as well as flowing screed.
  • Schlüter-BEKOTEC-EN 12 FK, -ENFGK, and -BRS are non-rotting and require no special maintenance or care.
  • 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.
  • The cover assembly of the Schlüter-BEKOTEC system is free of inherent stresses. Consequently, curling is virtually impossible to occur in the area. This is especially applicable in the presence of temperature fluctuations, for example with heated screeds.
  • The regular patterns of the Schlüter-BEKOTEC system evenly reduce tensions in the screed, which allows for constructing the screed without movement joints.
  • The design of movement joints can match the joint pattern of the tiles or stone covering, since it is not necessary to continue construction joints from the screed into the surface covering.
  • The floor heating system is easily adjustable and ideally suited for use with low temperatures.
  • Compared to conventional heated screeds, cover assemblies installed with a Schlüter-BEKOTEC system react much faster to temperature changes, since the volume to be heated or cooled is much smaller. Consequently, the heated floor system is particularly suitable for operation at low temperatures.
  • Schlüter-Systems offer a five year warranty.
