On my extension I want as good acoustic performance between floors as possible, I was planning on using rockwool slabs, the joists are 6inch, I was planning on doing a layer of 100mm rockwool and a layer of 50mm. Alternative is to try and squeeze 2x100mm in, or have a single 100mm and a 50mm air gap.
Anyway anyone who's done similar with any advice much appreciated.
On my last extension I just used loft roll but I'm hoping for better soundproofing with the rockwool acoustic slabs.
