sound proofing

Boba_Fett

Hi all
I recently took off old plaster and relined with plasterboard, in the alcoves either side of my chimney on the party wall i packed the wall out with a timber frame filled with rockwool covered in blue plasterboard yet there doesnt seem to be much sound proofing going on, as i can still hear next door, was this a waste of time and money, has anyone else done this, how did it turn out??

cheers

Perhaps because you've done the alcoves but the sound can still travel through the fireplace? I don't know.

I have builders doing soundproofing on my party wall (both upstairs and downstairs).They're using thick, "solid" insulation (?) with plasterboard which will bring each wall in by approx. 4 inches. I hope it works!!

Not sure what the stuff they're using is but will ask them when they're back Wednesday morning.

When I was looking into getting sound proofing I was told Rockwool was not a good enough sound insulator.

I haven't had it done yet. But I felt that those companies that went into detail on how the sound travelled within walls and floors had a better understanding. I was looking at 'Noise Stop Systems', 'Soundstop' who used acoustic matting and boards. All did say that it would not stop the noise completely but should lessen it and more width/space between walls the better.

Would be interesting to see if anyone who used the purpose built acoustic matting and boards got on.

Mine has been done now,the builders used rockwool (tonnes of the stuff) and some bars at the bottom of the walls as the plasterboard wasn't long enough.

I've lost at least 6 inches off the walls but it's worked
