Laying insulation screed with Staenis grid

This lightweight floor construction is ideal for rooms with limited floor construction height. In this situation, the Staenis grid makes it possible to insulate, level and quickly finish your floor structure with tiles or OSB panels.

A floor construction with insulating screed is 7 to 10 times lighter than a traditional screed and very easy to install. The tiles, laminate, multilayered parquet, etc. will also feel warmer due to the insulating effect of the mortar.

The tileable insulating screed can be tiled directly after 3 to 4 days of drying time, provided that a primer and a screed or tile adhesive layer are applied, which is 28 days for a screed.

With ordinary insulation screed, the Staenis grid serves as a wooden grid that can be easily adjusted in height. This allows you to screw OSB or Durelis sheet into the slats of the Staenis grid and then cover it with laminate or multilayer parquet, for example.


Insulation screed with OSB

Upstairs: Create a very light and insulating surface with a floating floor covering.

Tileable insulation screed with tiles

Low construction height: Create a very light and insulating surface on which you can glue tiles after a few days of drying.

Why insulating screed?

If you are going to install a new floor, it is best to provide a screed. When a screed is placed directly on the supporting floor, it forms a solid basis for your floor covering or floor finish. But you can also opt for insulating screed: a mixture of EPS granules, cement and water. Insulation screed offers a strength that is more than sufficient for a private home and also ensures good insulation of your floor. Did you know that a floor construction with insulation screed is 7 to 10 times lighter than one with a traditional sand and cement screed? Ideal for an attic or bathroom, for example. Tip: tileable insulation screed has a very high cement content and can be tiled directly.

Install insulation screed yourself with EPS pearls

Requirements and preparation: The handy thing about insulation screed is that you don't actually need many products to get started. Our insulating mortar with EPS pearls is available in handy bags. These contain ready-made insulation screed where you only have to add water. The insulating mortar can be mixed with a hand mixer in a tub, with a concrete mixer or any screed pump. When you have all this ready, you can get started. Remember that cement can be harmful to the skin, so protection is a must. Gloves are not a superfluous luxury. Please observe the safety precautions before you start.

Simply install insulation screed yourself

Placing insulation screed yourself does not have to be difficult, because you can simply buy our products from us in the webshop. The insulation screed contains EPS granules and all additives in the correct proportions, so you only need to add water. This makes it perfectly possible for the do-it-yourselfer to install insulation screed himself. The insulation mortar can be placed on any surface, on concrete vaults as well as on sand or wood. This way you can achieve the perfect filling of the substrate yourself and create a perfect basis for the screed.

Insulating properties of EPS beads

EPS beads are a very good insulation material that is mixed with cement to make insulation screed. The lambda value of the EPS beads is low, which means that the material has a high insulating effect. When you request a quote for insulation screed, it will often be stated that this type of insulation material is used.

Mixing process and acoustic benefits

When mixing the insulation screed, the EPS pearls are combined with cement, which gives the screed its strength and insulating properties. In some situations, insulation screed can also separate acoustically, which helps to reduce noise pollution.

Purchase and preparation of EPS screed

In most cases, self-build insulation screed is sold per bag and not per square metre, which makes it easy to order and have the quantity required for your project delivered. EPS screed is available ready-made, where you only need to add water to make the mixture.


Placing insulation screed yourself with EPS pearls is a simple and efficient way to insulate your floor. It offers many advantages, such as the prevention of thermal bridges, an increase in living comfort and living climate, and an environmentally friendly solution. With the right preparation and materials, you can install insulation screed yourself and thus create a perfect basis for further finishing layers and floor covering.

Frequently Asked Questions

Insulation screed is used in various situations. For insulating and levelling a concrete floor, on which utilities have been placed, after which a screed or insulation boards can be placed.

The Staenis grid can also be filled in with insulation screed for subsequent cladding with OSB or Durelis wooden panels or it can be filled in with tileable insulation screed for immediate tiling afterwards.

On average 7 to 10 times lighter than a sand cement screed.

Insulation screed is a mixture of EPS granules, cement and water. The lower the cement content, the better the insulating screed will insulate and the less load-bearing it will be. With a very high cement content, one can even tile the insulation screed directly, this is then called tileable insulation screed.

This varies from manufacturer to manufacturer. The average insulation values are between 0.045 and 0.087 W/mK

Yes, with tileable insulation screed. For this you should keep in mind that this tileable insulation screed is weaker than regular screed. So for use in a garage, we recommend screed where the tyres rest/run over.

Even where sprayed pur insulation, insulation boards or insulation screed has already been installed, we always recommend sand cement screed to be placed on top.

You may use a membrane for the installation of standard insulating screed in the Staenis grid. Afterwards it can be clad with OSB or Durelis tongue and groove boards.

For the installation of standard insulation screed as a filling layer (without Staenis grid), always place without a membrane.

You can improve the adhesion of the standard insulating screed by moistening the concrete surface with water the night before.

It is best to install tileable insulation screed without a membrane so it sticks to the substrate.

You can improve the adhesion of the tileable insulation screed by moistening the concrete surface with water the night before.

If there is a risk of rising damp, it is best to place a membrane. To be on the safe side, you can place a screed reinforcement net (in combination with the Staenis grid) on the membrane to avoid curving the insulation screed.

Yes, insulation screed and aerated concrete granules can be shipped, but count on paying a few hundred euros in shipping costs. Feel free to ask us for a custom quote.

Yes, but not with a wet system as with a screed. An insulating screed is, as the name itself suggests, insulating. Underfloor heating pipes must never be placed in a material that insulates, but a material that can transfer heat conduction well. We therefore recommend a dry underfloor heating system that is placed on top of the insulation screed, or a wet underfloor heating system in a screed.

The floor finish will always feel a few degrees warmer due to tileable insulation screed. This is because there is insulation directly under the floor finish. In fact, you do not need to install underfloor heating.

Yes, you must first place a primer + levelling compound/tile adhesive levelling layer on the tileable insulation screed to strengthen the surface.

Afterwards you can place a waterproofing cloth or spreadable waterproofing.
