Laying your own dry floor
By using dry products in combination with the Staenis grid, you can easily and directly cover your floor with OSB (or Durelis) and finish it with a floor covering such as laminate, multilayer parquet, etc. You also ensure that your floor structure becomes reusable/circular/environmentally friendly, thus contributing your part to the climate.
The Staenis grid serves as a wooden slatted frame that's easy to adjust in height and is ideal for attics. The grid can be filled with load-bearing fillers such as recycled aerated concrete granules or insulating fillers such as rock wool insulation, EPS beads, cork granules, and lime hemp, or without filler.
By combining the Staenis grid with recycled aerated concrete granules and OSB, you save on expensive gypsum fibre boards (+25 euros/m²) and expensive levelling granules.
You can screw the OSB or Durelis into the battens of the Staenis grid. Insulating, soundproof, and fire-resistant floor structure, depending on the filler and boarding used.
30 kg less CO² emissions per m² = 10 x less CO² emissions compared to screed
Up to 15 dB less contact noise by using felt pads under the adjustment screws.
Which lightweight floor build-up suits your situation?
Compare the fillers at the same layer thickness. Your choice affects not only the weight, but also insulation, acoustics and the feel underfoot.
| Filler | Dry weight at 7 cm | Best choice when |
|---|---|---|
| EPS beads | ±1.0 kg/m² | Minimum weight and strong thermal insulation are most important. |
| Cork granules | ±8.3 kg/m² | Better acoustics and a circular, natural filler are important. |
| Insulation screed soft | ±10.5 kg/m² | A stiffer, more solid feel underfoot is desired and wet installation is possible. |
| Aerated concrete granules | ±35 kg/m² | Maximum stability and a solid sound underfoot are more important than the lowest weight. |
The table shows only the dry weight of the filler at an average layer thickness of 7 cm. Indicative weights per m² for the other layers: 12 mm OSB approximately 7.5 kg, 18 mm OSB approximately 11.3 kg, 22 mm OSB approximately 13.8 kg, the green dry floor grid approximately 1.4 kg and the screed grid approximately 0.9 kg. The final floor covering must still be added.
Applications
Circular: By using aerated concrete, the dry floor becomes more load-bearing and sounds acoustically better when you walk on it.
As wooden joisting: In this project, the Staenis dry floor grating is used as a wooden grating. This is now easily achieved thanks to the fibre-reinforced dry floor grating.
dry floor: A standard dry floor with levelling granules tends to settle over the years, but with the Staenis grid, the floor always remains nicely at the correct height.
Filling layer: You can also use the Staenis grid in combination with cellular concrete levelling granules as an environmentally friendly fill layer under insulation boards.
