Ceiling Soundproofing

Many properties are built with plasterboard, or lathe and plaster, ceilings which are fixed onto wooden ceiling joists with boards or a chipboard floor laid over the joists, thereby creating a void or cavity.

In order to stop airborne sounds transferring through a ceiling dB Soundproofing London would look at insulating the cavity between the ceiling and floor. This method of soundproofing a ceiling is carried out on new build and converted properties to meet the current regulations. If you are soundproofing an existing ceiling call dB Soundproofing London.


Types of Ceiling Soundproofing

 

Genie clip system: retain existing ceilingAcoustic-Wool

  • Retain existing ceiling and install genie clip to ceiling joist
  • Place furring strip in position on genie clip
  • Compact fit RW3 50mm acoustic rock wool between furring strips
  • Install 1st layer of 19mm acoustic plank
  • Seal all cavities with acoustic & fire rated mastic
  • Install final layer of 12.5 mm acoustic plasterboard
  • This system will reduce the ceiling height by approximately 72mm

Independent ceiling: retain existing ceilingIndependent-Ceiling

  • Construct wooden batten frame, leave a gap of approx. 25mm from the original ceiling
  • Insert RW3 100mm acoustic rock wool
  • Install resilient bar with 1st layer of 19mm high density plank plasterboard
  • All cavities and gaps will be filled with acoustic & fire rated mastic which will form an air tight barrier
  • A final layer of 12.5mm acoustic plasterboard will then be added
  • This system will reduce the ceiling height by approximately 170mm

Resilient Bar: – remove existing ceiling

  • Remove existing ceiling
  • Compact fit RW3 100mm acoustic rock wool to be placed in the 400mm gaps of the joist, to form a sound barrier
  • Resilient bar to be fixed to joist with first layer of 19mm high density plank plasterboard
  • All cavities and gaps will be filled with acoustic & fire rated mastic which will form an air tight barrier
  • A final layer of 12.5mm acoustic plasterboard will then be added
  • This system will reduce the ceiling height by approximately 35mm
