(see diagrams 5 and 7). The tiles manufacturers are then embedded and secured into place with a Sikaflex Pro 11 FC type sealant between the lower lips of the tiles and the upper wing of the rail.

? For Phoniceram® dB: ? For Phoniceram®: (see diagrams 4,5 and 6) When the framework is installed (vertical and horizontal adjustments thanks to brackets), the spaces are filled with an acoustic insulation, reference Rockwool 381-652 (thickness: 80 cm, density: 147 kg/m
3 )thickness 80 mm 3 ) or Protisol by Eurocoustic.This insulator can be covered with a black PVC screen (density: 70 gr/ m
2 ). The thickness of the insulator must be equal to the thickness of the space to be filled so that the rail abuts the face of the insulation. The rail is fixed onto the frame with a wood screw (for wooden frames) or a self-tapping screw (for metal frames) with a theoretical interaxial distance of 305 mm (average theoretical gauge indicated on the pallet).

Even thought it is easy to replace independent tiles, it is impossible to remove an entire piece.
