StaenisGrid Floor Structure: Tips for Insulation and Stability

Customer asked if the StaenisGrid, filled with cellular concrete granules, can be used directly on rigid insulation boards for his floor construction. Employee replied that this is not possible because the grid would sag. He suggested filling the grid with cellular concrete granules, placing insulation boards on top, then loosely laying 12 mm OSB and screwing down 18 mm OSB.

  1. Fill the grid with cellular concrete granules and reinforce where necessary.
  2. Place the insulation boards on top.
  3. Place 12 mm OSB loosely on the insulation boards.
  4. Screw the 18 mm OSB into the 12 mm OSB.

For the bathroom, he referred to a specific floor structure for the bathroom. More information about this can be found at the specific floor structure for the bathroom.
