Why the Staenis grid

This light floor construction with load-bearing fillers, such as levelling granules/cellular concrete, is ideal for levelling a room dry. By using the Staenis grid, expensive gypsum fibre floor sheets are saved, resulting in a much easier installation. It is also possible to work with cellular concrete instead of the expensive levelling granules. The floor structure is removable and can be reused without waste.

Benefits

  • Achieving a perfect end result without any experience
  • Can be covered directly with double staggered wooden Durelis or OSB panels
  • Can be covered immediately afterwards with many types of floor finish
  • Lightweight, fire-resistant and sound-absorbing floor construction
  • Very fast, light and dry installation
  • Possibility to insulate your low floor construction over the full thickness.
  • Spread floor works over several days (no stress during installation)
  • Circular floor construction through dry ecological & sustainable fillers

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. Pour the load-bearing levelling granules or aerated concrete into the grating and level it with a screed iron on the top of the Staenis grating.
  3. Place on this at least an OSB of 22 mm thickness. Screw the wooden plate into the battens of the Staenis grid. If necessary, apply double plating for extra strength.
  4. With a single plating on the load-bearing fillers, the 22mm OSB will still spring slightly. With a double plating (12mm + 18mm) the deflection is completely gone. (1 ton/m² compressive strength)
