Ground floor ceiling down. Need to Sound insulate from upstairs. I have in the past put resilient bars in with acoustic mineral wool and re-boarded and it has reduced noise transmission pretty well.
The Acoustic type seems to cost more than when i bought before. Would it be better to put 150mm of Acoustic insulation (3 layers of Earthwool Acoustic Roll 50mm 15.6m2) or l layer of Knauf 200mm Super Top Up Loft Roll Insulation - 5.61m2 ?
Room is between 5-5.5m2 the Loft roll is 1/3 cheaper
