Manual and important points of attention for the Staenis grid
Insulation screed, finished with OSB or Durelis boards

Processing temperature

Only install insulation screed at temperatures between 10°C and 20°C, as this ensures that the insulation screed will not become sandy or come loose. Also make sure that the insulation screed feels cool/cold during installation or that the ambient temperature does not drop below 5°C.

Installation method

• Pre-positioned:
  1. Place all StaenisGrids in the room
  2. Adjust all StaenisGrids to the correct height
  3. Fill the StaenisGrid with tileable insulation screed
  4. Level the tileable insulation screed on top of the grate.
  5. Check the height of the grid
  6. Repeat until the entire space is finished

* Insulation screed is so light that you can easily walk over the grid with a filled tub of tileable insulation screed and pour it into the StaenisGrid.

Placement of StaenisGrid

• Place the frames by clicking the slats and legs together.
• Shorten the slats at the wall by sawing or grinding them. The maximum distance from the grid to the wall is 5 cm.
• At the connection to the wall, you can stabilize the grid by clicking legs sideways into the slat. At both ends of the slat, a third type of click connection can be seen. This allows you to connect two slats with a sideways leg to each other using a slat. Note that the slat then only clicks in one direction.
• Raise or lower the StaenisGrid with a screwdriver by turning the adjustment screw to the left or right.

Height adjustment

The highest levelness can be achieved with a laser that you align with a line on a wooden tool/beam or folding ruler. Once you use a digital receiver, the insulation screed will inevitably cause height differences of a few millimeters. A digital water level hose is also not recommended. Try to use a digital receiver or water level hose only to mark out a few points, so that you can level everything in between using a stretched string or aluminum straightedge.

Accuracy

We ask you to pay close attention to the height adjustment during installation and to regularly check the flatness with a long aluminum straightedge or laser.

Placement of insulation screed

• Fill the StaenisGrid with insulation screed and place it just slightly higher than the top surface of the grid.
• Take a long screed iron or aluminum straightedge, hold it slightly at an angle, and drag all the excess insulation screed off the grid. This way, the screed is now level with the top surface of the grid.
• Check and correct each cell for flatness to avoid cavities in the grid.

Placement of the OSB or Durelis board

• Let the insulation screed dry for a few days and then smooth it extra flat using an aluminum straightedge. Remove all loose EPS beads using a vacuum cleaner.
• Place an OSB or Durelis board on the substrate and screw it into the battens of the StaenisGrid. The screws must be 2 cm longer than the thickness of the wooden board and may have a diameter of 3.5/4/4.5 mm.
