Partition thickness is 15-16 cm.


Step 1

Mount two runs of KNAUF SP 50/50 stud profile according to KNAUF process chart (in case of big height of the room, 75 or 100 mm profile can be used).


The guide elements of the frame must not adjoin the floor and the ceiling rigidly. Apply two layers of MaxForte damping tape under the guide profiles. Use tape 100 mm in width under each part of the partition. Stick the tape in two layers.

The optimum spacing between the metal frame studs is 600 mm. In order to reinforce the frame (if loads on the future wall are expected), doubled stud profiles fastened to each other with self-tapping screws can be mounted.

Step 2

Sheathe the partition with gypsum fiberboard (GF 10 mm) on one side.


Important! Sheathing sheets should adjoin the floor, the ceiling and the side walls through MaxForte damping tape mounted according to Step 1.

Step 3

Fill the space between the metal frame studs tightly with MaxForte-ECOplate 60 kg/m3 sound absorbing material. Fill both runs of the frame: the right and left halves at once.


Step 4

Sheathe the second side of the partition with GF sheets covering the sound absorbing layer.


Step 5

Treat the seams between the GF sheets with MaxForte silicone sealant.


Step 6

Fasten the gypsum plasterboard (GP) sheets 12.5 mm in thickness on both sides.


Seam spacing should be ensured: joints between GF sheets and joints between GP sheets should be placed apart at a distance equal to half of the sheet width.

Step 7

After the sheathing has been mounted, cut off the excess of the damping tape and treat the seams around the perimeter (i.e. junctions of the soundproofing structure to the walls, the floor and the ceiling) with MaxForte non-drying silicone sealant.

Joints between GP sheets have to be puttied during further finishing.
