THIN SOUNDPROOFING OF CEILING

Potolok VibroStop Standart

Thin soundproofing of the ceiling takes 4-5 cm.

PROCESS CHART:

Step 1

Before starting works related to soundproofing of the ceiling, examine the ceiling thoroughly for cracks. Cracks have to be pointed and filled up with gypsum plaster or cement and sand grout (CSG).

Examine locations where slabs adjoin walls. If there are any gaps, they should also be eliminated.

Step 2

Mount the frame of the single-level suspended ceiling from KNAUF CP 60/27 mm ceiling profile elements. Fasten the load bearing elements to the ceiling using VibroStop Standart vibration mounts.

Guide elements of the frame must not adjoin the walls rigidly. Apply two layers of MaxForte damping tape under the guide profiles.

Important! After the frame has been assembled, unscrew concrete nails from KNAUF CP 27/28 mm guide profiles.

Step 3

Fill the space between the metal frame studs tightly with MaxForte-ECOplate 80 kg/m3 sound absorbing plates.

Step 4

Mount sheathing materials in the following sequence:

а. Gypsum fiberboard (GF) 10mm in thickness (or gypsum plasterboard 12.5 mm in thickness).

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

c. Gypsum plasterboard 12.5 mm in thickness.

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.

d. Joints between GP sheets have to be puttied. 

There should be two layers of MaxForte damping tape between the sheathing sheets and the walls.

After the ceiling soundproofing has been mounted, treat the seams along the perimeter (i.e. where the soundproofing structure adjoins the walls, the floor and the ceiling) with MaxForte non-drying vibroacoustic sealant. The use of sealing foam is not allowed!
