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.

Directly suitable for many types of floor finishes

Lightweight (10 times lighter than a sand-cement screed) and sound-insulating floor

Floor construction manual

1. Place the StaenisGrid and adjust it to the correct height using a screwdriver. If necessary, use Staenis extension legs or sawn wooden blocks under the Staenis legs to adjust it to a higher level. 2. 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. 3. Place an OSB board with a minimum thickness of 18-22 mm on the StaenisGrid and screw it to the slats. Alternatively, you can use a 12 mm board, but then you must apply sufficient construction silicone under the OSB board to prevent sagging when walking over it. 4. 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. 5. 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. 6. To prevent moisture infiltration from the insulation screed, we recommend filling any gaps in the concrete subfloor with PU foam or sealing them with mortar before installation. 7. Tip: Glue all the legs to the substrate with PU foam, so the height adjustment remains correct after leveling. 8. Permitted floor coverings: floating floor coverings such as multilayer 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.

Insulation screed or insulation mortar in ready-to-use bags

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.
