SS says that the normal insulation batts for thermal purposes in the subfloor (between first floor and ground floor ceiling) won't help at all in blocking the sound, which I understand. But he goes on to say that even if clients choose to put in acoustic insulation batts in the subfloor, they won't help too much either because of the timber joists, and that carpet with good underlay will be much more effective in blocking the sound than acoustic batts in the subfloor. Is that true?
Do you find the sound from people walking on the first floor obvious to the ground floor? Does carpet help much? Did you install any insulation batts in the subfloor, and how effective is that in blocking sound?
Hmmmmm interesting as we were going to upgrade to the acoustic insulation, I still think it will reduce/limit the noise compared to the normal insulation! BUt we are going to be doing the flooring after hand over so we will be going a pretty premium underlay as well as carpet!
