Hi bro... thanks for your reply. She suggested using rockwool for each of the area (2 toilets + kitchen)... at 1.2k per area?? Is she nuts? Either that, or she's trying to profiteer... basket.
Yar, agree with you. That's why I wanna make sure I over-compensate to reduce the sounds now, esp the MBR piping as my fiancee is a light sleeper.
My 1st time renovating, I hope so as well. *fingers crossed*
PS: diamdiam... really lives up to his nick, lol.
