A really good base:

Floor insulation with flapor

Nowhere is more important than your own home – this is why having optimum thermal insulation at home is so important. But the requirements in terms of the type and thickness of the insulation material are very different depending on where it is being installed. So it’s even better when you can rely on a material that has flexible and versatile uses: flapor. It simply stops the cold getting in.

The flapor thermal insulation board EPS-W20 – developed for thermal insulation with loading – provides optimum insulation between floors and the ground where there are temperatures of just 8 to 12°C all year round. Appropriately thick flapor thermal insulation therefore makes a home cozy and warm from the ground up.


flapor is not just outstandingly suited to preventing heat loss, but also noise: Integrated in the floor structure of the intermediate floors, flapor footfall sound insulation boards absorb every step. They are also elastic, highly resilient and can be laid easily and quickly in floating screed.

The key requirement for the footfall sound insulation to work perfectly is to avoid any acoustic bridges between the screed and adjacent brickwork.

The advantages of footfall sound insulation boards.

  • Low levels of compression
  • Suitable for all levels of traffic in residential buildings
  • Proven to work in building construction for decades
  • Moisture-resistant
  • Easy to lay
  • Outstanding value for money

Processing recommendation for screed

  1. Prepare ceiling surface
    The bare ceiling must be thoroughly cleaned before starting the footfall sound insulation works. Any protruding concrete parts or reinforcement bars or lumps of mortar must be removed. If necessary, a bed of sand or flaporplus EPS-W20 may also be applied as a leveling layer. This will allow you to lay installation cables between or in flaporplus EPS-W20 boards. If moisture is expected to penetrate down through the insulation boards, waterproofing or a PE foam film should be applied to the ceiling.
  2. Lay edge strips
    Provide PE edge strips all the way round the wall (prevent acoustic bridges).
  3. Lay insulation boards
    Starting in a corner, lay out the boards loosely in rows. Bump up to flapor EPS-T footfall sound insulation to prevent any acoustic bridges. Lay in combination with offset butt joints, although you should start by alternating between full and half boards.
  4. Lay separating layer
    Cover the insulation boards which have been laid with a separating layer. The paths of the separating layers must overlap each other by at least 10cm and be pulled up on all wall sides to the top edge of the PE edge strips.
  5. Apply screed
    Apply screed in accordance with the manufacturer’s instructions.
