Introduction to the project:

The System with resilient bars has been designed to act as a shock absorber in structure. When the sound hits the decoupled layer of sound plasterboard it will begin to vibrate, however since the plasterboard is isolated it will absorb most of the vibrations, meaning they are unable to reach the main structure. Also, we will install the sound blocking membrane between two sound plasterboards.

Stages 1/2/3/4/5/6/7/8/9

Quotation and instructions for the soundproofing of the party wall:

1) decouple the ceiling and the sidewalls from the main structure (not applicable on the solid structure)
2) create the timber partition with a minimum of 20mm gap away from the main structure
3) insulate the new partition wall with acoustic insulation
4) install the resilient bars system on top of the new partition wall
5) install the first layer of the sound plasterboard and seal the gaps around the entire wall (leave the gap on the sides, minimum of 5mm)
6) install acoustic mat on top of the first layer of the sound plasterboard
7) install acoustic foam on top of the acoustic mat
8) install the second layer of the sound plasterboard and acoustic sealant around the new structure (note that the first layer of the sound plasterboard need to be 15mm and second 12,5mm)
9) plaster the walls

The new wall is ready to paint!
