This is done is by removing the ceiling drywall and inserting anything from r 13 to r 20 fiberglass insulation in the joist space. We recommend using 100mm of acoustic floor insulation and a density of between 60kg m 80kg m to increase the soundproofing between floors. The panels should be covered with an acoustic fabric to prevent fibers from becoming airborne as with all insulation the density impacts its noise reduction ability as does its.
