Cleaneo® Akustik Tiles installation

Cleaneo® Tiles
Acoustics and design with no restrictions

The Knauf tiles ceiling system is based on the concept of modular suspended ceilings and is ideal for hiding of various installations, cables and air ducts. Additional devices such as detectors or lights can be installed in these ceilings. In addition, the Knauf tiles ceiling system can significantly improve the acoustic environment in the rooms. The Knauf tiles ceiling system consists of a suspended gridwork (made of lightweight metal profiles T15 or T24) and Cleaneo tiles. The structure is suspended to the main ceiling by adjustable hangers, and the tiles are placed on the profiles of the gridwork.

Knauf tiles ceiling system

The Knauf Cleaneo tiles for ceilings are gypsum boards with dimensions 600 x 600 mm, which are produced in two variants: without perforation - ordinary and acoustic - perforated.

Configuration of the gridwork



The locations of the Knauf ceiling hangers are marked and the hangers are fixed with steel dowels suitable for the main structure. The distances between the hangers, profiles and friezes are determined in advance based on the ceiling system according to the specified scheme. For mounting with spring hangers in the T-profile there is a special hole in which the hook of the hanger ends, which must be tightly closed.

Hangers and their elements

The T profiles on both sides are shaped by means of special joints at their ends so that they will be able to extend. The joints of the T profiles are located evenly at a maximum distance of 10 cm from the point of suspension. Perpendicular to the T-profiles in their punched holes, the cross-sections are mounted so as to obtain the desired grid. The arrangement of the transverse T profiles is based on the dimensions of the tile. At all intersections of the raster, the profiles must close 90 degrees.

The finish of the ceiling to the wall is accomplished with a corner profile, which is attached to it with dowels. The bearing components of the grid must not be fixed to the L profiles. Finally, Knauf ceiling tiles are placed through the profile grid. When installing lighting, sound and other fixtures, the structure of the raster ceiling must not be affected. The load-bearing capacity of the tile on the suspended grid ceiling complies with the requirements of EN 13964:2014. The tiles can be applied under normal living conditions. Luminaires weighing up to 1.8 kg can be built into 12,5 mm elements in an opening designed for them in the tiles with a diameter of 65 to 265 mm without reinforcing the structure. If the openings diameter is greater than or equal to 160 mm, the built-in body can weigh up to 2.5 kg. Luminaires weighing up to 0.9 kg can be built into tiles with a thickness of 9.5 mm in a hole designed for them in the tiles with a diameter of 65 to 265 mm without reinforcing the structure. Under these conditions, the ceilings correspond to deformation class 1 - deflection is less than 1,2 mm. For larger elements, it is necessary to add additional reinforcing elements. These additional elements must reach and transfer their load to the bearing profiles of the system. The suspended structure must be checked for load-bearing capacity, taking into account these additional loads. Suspension of loads larger than the specifiedones is done independently,without loading the ceiling.
