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.
