Ceiling
Treatment Using Plain or Decoupled Barriers
Barrier
material installed on the underside of the joists can be used
to control sound from transmittting through the floor / ceiling
structure.
Absorptive
material is installed in the spaces between the joists. Generally,
4 to 6 inches of standard fibreglass or mineral wool is sufficient.
This will prevent resonance in the cavities between the joists.
Plain or decoupled barrier material is then applied to the
underside of the joists.
Drywall can be installed directly over the barrier material
or in combination with the RSIC-1
Sound Isolation Clip System.
