Insulating screed floor structure
Information
This lightweight floor structure forms an ideal insulated base for your parquet, laminate, cork, carpet, etc. The insulation screed can be covered after a few days of curing with a wooden OSB or Durelis board and screwed onto the Staenis grid, which in this situation serves as a wooden joist structure.
Advantages
- Achieve a perfect end result without experience
- Can be covered with wooden Durelis or OSB boards after 3 days
- Directly suitable for many types of floor finishes
- Lightweight (10 times lighter than a sand-cement screed) and sound-insulating floor
- Possibility to insulate your low floor construction over the entire thickness.
- Spreading screed work over several days (no stress during placement)
Floor construction manual
- Place the StaenisGrid and adjust it to the correct height using a screwdriver.
- Mix the ready-made insulation screed from bags with water (see webshop for the amount of water) and pour it into the grid. Level it with a screed bar on top of the Staenis grid.
- Place at least an 18-22 mm thick OSB on top of this. Screw the wooden board into the slats of the StaenisGrid.
- Tip: Depending on the type of floor finish, you choose the thickness of the OSB. A thin floor finish requires a thicker OSB, while a thick floor finish can be combined with the minimum OSB thickness for this floor structure.
- Tip: Keep in mind that not every substrate is identical. For optimal adhesion to a concrete surface, it is advisable to thoroughly moisten it with water the evening before. Make sure that no puddles of water remain before applying the insulation screed. You can also consider adding a bit of primer to the water to prepare the substrate even better.

We deliver insulation screed in bags to your home
The insulation screed is pre-mixed with new EPS beads, combined with cement, water, and specific patented additives.
The EPS beads have a specially small diameter of 2mm-6mm, in order to achieve an even flatter result with the StaenisGrid.
The insulation screed in bags is easy to transport and makes it possible for you to insulate your floor yourself.
This non-walkable insulation screed can be used as insulating infill in the StaenisGrid, single or double layered with at least 18mm OSB. It can also be used as an insulating leveling layer, with a screed on top.
