Product Information

The insulating screed/insulation mortar is ready-mixed, composed of EPS beads mixed with cement and additives. The EPS beads are specially designed with a small diameter of 2-4 mm to achieve an even flatter result with the Staenis leveling grid. You only need to add water and mix.

To be used as insulating filling in the Staenis leveling grid, single or double covered with at least 18 mm OSB (depending on the chosen floor finish). Can also be used as an insulating fill layer without a grid, over which a screed is placed.

Please note:

- Do not store bags outside or in damp areas.

Required Quantity

- 10 bags = ± 10 m² with a thickness of 5 cm
- 1 m³ = 1000 l = 150 kg = 20 bags
- 1 Sack = 50 Liter = ± 5 cm/m²
- 1 pallet = 40 bags
- Consumption: 1 bag of insulating screed/insulation mortar per m² at 5 cm thickness.

Specifications

This insulating screed/insulation mortar has better insulation value than the tileable version but with a lower compressive strength (note: this compressive strength is still more than sufficient for a private residence). We recommend this insulating screed/insulation mortar if the Staenis leveling grid, filled with insulating screed/insulation mortar, will be subsequently covered with OSB or Durelis wooden plates and then finished with, for example, laminate, cork, etc.

- A very light and hard insulating screed with a high pressure resistance.
- The insulating screed fills all cavities under and between pipes and tubes for 100%.
 This makes the best choice as insulating screed for floor heating.
- Easy to use and various floor insulation applications are possible.
- Easily make your own insulation screed & quickly get to work: in one go you have installed an insulation screed all by yourself.
- Accessible after 48 hours at 15°C

Technical Specifications*:

*Tried and tested internally, at eps-suppliers and/or at the European recognised certification body Buildwise, according to the current standards EN 12667 & EN 1015-10, producers based on cement.

* Do not use in garages or where the load is too high.

Prepare insulation screed:

Mix the entire contents of the bag (50L) with 4.5 to 5 liters of water, for 3 minutes in a mixing bowl with hand mixer and for 5 minutes in a concrete mixer.
Tip: Start by adding 4 liters of water and add additional water if necessary. Too much water will wash the cement slurry off the EPS beads, while too little water will hinder the bonding of the cement.

Attention: video is still available on 70L bags!

Subsidies and technical indication

There is no automatic subsidy for this insulating screed. The former Fluvius subsidy for DIY roof or attic-floor insulation could be applied for no later than 30 June 2026. It is therefore not a general reference for floor insulation.

For floor insulation, the Mijn VerbouwPremie voor vloer may still be relevant for owner-occupiers in income category 3 or 4 and landlords renting to a social housing company. The work must be carried out by a contractor, the floor must achieve at least Rd 2 m²K/W and the invoice must be at least €1,000 excluding VAT. This subsidy does not apply to DIY installation. The building, the work and the applicant must also meet the remaining conditions.

View the current subsidy conditions on Vlaanderen.be or search for local and provincial subsidies through Premiezoeker. An existing EPC label subsidy or BENO pass is relevant only if you already have a valid file.

Technical indication: with λ = 0.045 W/mK, R = d / λ. For Rd = 4.5, the required thickness is d = Rd × λ = 4.5 × 0.045 = 0.2025 m ≈ 203 mm. This calculation alone does not determine subsidy eligibility.
