Screed with insulation screed

Information

This floor structure consists of two layers: the screed and the insulation screed. The screed ensures that the floor is made flat and firm. This is necessary to create a stable and flat surface for the finishing floor.

An insulation screed is placed under your screed as insulation for your floor construction. This can be cast on an uneven surface and around pipes.

Insulation screed is composed of EPS beads mixed with cement and additives to obtain thermal insulation.

The insulation screed layer has a high load-bearing capacity, does not require reinforcement and has a seamless finish with less construction height, which is useful for renovations.

Benefits

  • Achieving a perfect end result without any experience
  • Compartment of the screed = crack-free screed
  • Replaces an uncoupling mat = savings of an average of 30 euros/m²
  • Replaces the steel reinforcement mesh = savings of an average of 3 euros/m²
  • No expansion joints needed in the screed = savings of an average of 3 euros/linear metre
  • Spread screed work over several days (no stress during installation)
  • Much faster start-up of underfloor heating possible = faster construction process
  • No dishing/cupping of the screed = perfectly flat screed

We deliver screed in a silo to your home (only in Belgium)

Chape in silo delivered to home in Belgium

By simply pressing a button on the silo, you can prepare fresh sand cement screed at a rate of 3 m³/h and this without time pressure to process the large amount of sand cement screed.

There are 2 separate compartments in the silo. 1 part filled with sand (0/4-0/7mm) and the other part filled with dry cement (250kg/m³). These are only mixed with water at the moment you wish.

The big advantage of this is that you can make fresh sand cement screed at your own pace and for a few weeks.
