Dry floor with glass wool or cork granules

Information

Non-load-bearing fillers such as glass wool, cork granules or EPS beads are ideal for providing additional insulation to a floor structure. In this situation, the Staenis grid serves as a wooden grid. The floor structure is demountable and can be reused without waste. If additional load-bearing capacity and strength are required, it is best to use levelling granules (cellular concrete) or insulation screed as a filler.

Very lightweight floor structure

Very fast, light, and dry installation
Simple transport from the front door, through the finished house, to the upper floor or attic space.
Possibility to insulate your low floor construction over the entire thickness.
Spreading floor work over several days (no stress during installation)

Floor construction manual

1. Place the fiber-reinforced green drying floor grid and adjust it to the correct height with a screwdriver. 2. Glue all legs to the substrate with PU foam, so that the adjusted height is maintained during installation. With the old black and yellow Staenis grid, 8 extra legs had to be placed per square meter and reinforced with lime or cement mortar; thanks to the fiber-reinforced green version, this is no longer necessary. 3. Pour the loose cork granules or EPS beads into the spaces of the Staenis grid and level them out. 4. Place a flat OSB or Durelis panel on top. Option 1 – single panel: use one 22 mm panel and screw a wooden reinforcement strip (± 9 cm wide × ± 2 cm thick × ± 40 cm long) under each seam in each 50 × 50 cm grid cell; if desired, glue the seams with D4 wood glue for extra rigidity. Option 2 – double plating: first place a 12 mm panel. Stand on the panel while screwing and insert 2 screws per 60 cm length, per row of 50 cm), place a second panel (min. 18 mm) on top of it, staggered, and screw the top one into the bottom one; for maximum rigidity, you can also use two 18 mm panels. 5. Choose between option 1 or 2 and the board thickness based on the floor finish. Thin, flexible finishes (cork, carpet and vinyl) require double OSB or Durelis plating, while for a thick or rigid floating floor (multi-layer parquet, laminate) option 1 with one board plus reinforcement is sufficient. 6. Tip: To prevent loose granules from rolling away or flowing through holes and cracks, it is advisable to carefully seal all openings in the concrete substrate beforehand with PU foam or mortar. 7. Permitted floor coverings: floating floor coverings such as multilayer parquet, laminate, cork, carpet, and vinyl. Always follow the installation instructions of both the floor covering manufacturer and the store where the purchase was made.

We deliver cork insulation granules in bags to your home

Moisture-resistant expanded cork insulation granules for thermal and acoustic insulation of floors and ceilings.

The cork insulation granules in bags are easy to transport and make it possible to dry-level your floor yourself.

Cork insulation granules are not load-bearing, so you need 8 additional StaenisFeet per square metre for extra load-bearing capacity.

Fibre-reinforced levelling grid

Fibre-reinforced leveling grid for dry floors

With these green, fiber-reinforced slats, you do not need to install 8 extra leveling feet per m² when using a non-load-bearing filler in the leveling grid. This makes the installation process much smoother.

The 5 leveling feet must be reinforced with mortar and bonded to the substrate with PU foam.

These fiber-reinforced slats are 2.5 times stronger than the standard black slats.
