Definition
Sound insulation reduces sound passing through walls, ceilings and floors, by adding mass or layers such as rock wool inside partitions, separating floors with a resilient layer, and sealing gaps around services.
Why it matters on a project
It matters between bedrooms, majlis, cinema rooms and adjoining flats. Adding it after finishing is costly and less effective.
Measurement and pricing
In square metres by type and thickness.
Common mistake
Insulating the wall well but leaving gaps around pipes and doors unsealed, so sound leaks through them.
Frequently asked questions
Sound insulation or acoustic treatment?
Insulation stops sound passing between rooms; treatment reduces echo inside a room.
Is wool inside the partition enough?
It helps a lot, but gaps and doors must be sealed too.
