Screed floor structure insulated 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

1. Pour the insulation screed and make sure that the insulation screed layer is flat (max. 2 cm difference in height), so that installation with the Staenis grid is possible. Then cover it with a layer of plastic and install the floor heating if necessary. 2. Place the Staenis grid and adjust it to the correct height with a screwdriver. As standard, screed is poured 8 cm high/thick. 3. Fill in the Staenis grid properly with screed and flatten it on the top of the Staenis grid. Sprinkle some screed on the surface and polish with a large sanding board. This ensures that the remaining holes are filled and a good bonding strength to the tile is guaranteed. Always place an expansion strip or edge insulation along the walls. 4. Tip: At the start you must first align the grid globally. Then fill it in with the screed. At this point the grille may move or sink slightly - this is normal and part of the process. Only after this initial setting and the addition of the screed, you need to finely align the grille to the nearest millimetre. 5. Tip: Place a foil over the freshly placed screed to prevent it from drying out too quickly and silting up. 6. Approved floor coverings: natural stone and ceramic tiles, multi-layer parquet, laminate, cork, carpet and vinyl. Always follow the installation instructions of both the floor covering manufacturer and the store where the purchase was made, and, if necessary, first apply a leveling layer or waterproofing.

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

Screed 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.
