Insulating screed floor construction 6

Why the Staenis grid

This light floor structure forms an ideal insulated surface for your parquet, laminate, cork, carpet, etc. After a few days of curing, you can cover the insulating screed with a wooden OSB or Durelis sheet and screw it on to the Staenis grid, which in this instance serves as a wooden grid.


  • Achieving a perfect end result without any experience
  • Can be clad after 3 days with wooden Durelis or OSB panels
  • Can be covered directly with many types of floor finish
  • Lightweight (10 x lighter than a sand cement screed) and sound-absorbing floor
  • Possibility to insulate your low floor construction over the full thickness.
  • Spread screed work over several days (no stress during installation)

Floor construction manual

  1. Place the Staenis grid and adjust it to the correct height with a screwdriver. Use sawn wooden blocks under the Staenis legs to adjust higher (Staenis extension legs cannot be used for this).
  2. Mix the ready-to-use insulating screed from bags with water (+ the bag of additives) and pour it into the grid. Flatten these with a screed iron on top of the Staenis grid.
  3. Plaats hierop minimaal een OSB van 18 mm dikte. Schroef de houten plaat vast in de latten van het Staenisrooster.
