Remedial treatment for ceilings

The principle used in the wall treatment can be equally applied to ceilings, the idea being to build a new ceiling below the existing one. The following steps for construction are often used:

  • attach wall plates to the walls to give the shortest room span and run new ceiling joists between them
  • fix mineral wool between the new ceiling joists, or drape it over them
  • line with two plasterboard layers, making 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.
