6.10.15Acoustic performance

LSF walls and floors shall have adequate resistance to the passage of sound.

Internal walls and floors should be in accordance with relevant building regulations.

Separating walls

Separating walls should be in accordance with the design. Care should be taken to avoid gaps:

  • between mineral wool quilt or batts
  • between internal lining board layers
  • between cavity barriers
  • around openings for services.

Separating floors

The floating part of a floor should be separated from the main structure and surrounding walls by a resilient layer. Where boards are laid loose over insulation without battens, joints should be glued.
