Screw the acoustic panels to the joists in the ceiling by screwing the black plaster screw (35 mm) through the black acoustic felt and into the battens.
We recommend 15 screws per panel.
The acoustic panels have a felt side and a slat side.
The sides of the acoustic panels therefore fit together, so that the joints themselves will be hidden behind the lamella of the previous panel.
When you install the panels, push the panels together (felt side to slat side) until there is 13 mm between the slats in the joint. Do NOT push the panels all the way together. To keep the right distance, you can take a slat of a color sample and put it between the two panels.
If you want a game in the pattern on the ceiling, you can shift the position of the panels from each other.
