Thin noiseproofing of the ceiling takes 4-5 cm.


Step 1

Before starting works related to soundproofing of the ceiling, examine the ceiling thoroughly for cracks between slabs. 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

Fasten MaxForte-SoundPRO rolls to the ceiling throughout the area using umbrella dowels 70 mm in length (2-3 dowels per m2). Rolls should be laid with an overlap of 4-5 cm. Smear the joints between MaxForte-SoundPRO rolls thoroughly with single-component rubber or seal with reinforced mounting tape.

Step 3

Mount KNAUF CP 60/27 mm metal frame to the ceiling according to KNAUF technology.

Important! The ceiling system should be vibration isolated from the walls. Apply two layers of MaxForte damping tape under the guide profiles.

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.

The sheathing sheets must not touch the adjoining walls directly (as well as the profile guide elements).

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