Remedial treatment for walls

The following steps for construction are typically used:

  • build a studwork frame, attached to the ceiling and floor but not fixed to the original wall
  • hang mineral wool inside the cavity, and tack between the studs or to a batten on the wall
  • line the studwork with two layers of plasterboard, (make sure the joints between the sheets in the first and second layer do not coincide)
  • seal the perimeter and all other sound paths with flexible sealant
