Hi,

I live in a modern (uk) 3 storey mid terrace townhouse, and I can hear my neighbours talking through our "party walls", if I stand in the middle of my room. Our party walls are breeze block with what I believe to be a standard uninsulated stud (plaster) wall on our side. If I put my ear to our plasterboard wall, I can clearly hear my neighbours talking. To get around this I would like to insulate the walls, fine - but, what I dont understand, is that I can hear my neighbours talking from their ground floor room, in my third floor room, if I put my ear to the plasterboard on our side, likewise, I can also hear what happens in our ground floor rooms, in our third floor rooms, if i press my ear to the plasterboard on our side, the reverse is also true, in that I can hear my neighbours in the top of the house of their side, from the bottom of the house on our side. How is this possible? and how can I insulate against this?

Thanks

This is the beauty of plaster...its a great sound transmitter. In order to reduce this problem you will need to replace the plaster with sheet rock / drywall and hang it on resilient channel.
Make sure you insulate the cavity and seal any and all holes with caulk.

Sorry, I should of said plasterboard, which I believe is the UK version of drywall. How easy is it to remove plasterboard? Is it possible to blow insulation into the plasterboard wall?

Option A: I was thinking of removing the plasterboard, insulating with mineral wool (do you know of any good UK brands), using genie clips (resilient channel) and covering with acoustic plasterboard (do you know of any good UK brands)?

Option B: Soundstop panels on top of my existing plasterboard (http://www.soundstop.co.uk/ZM20PA.php)

Option C: acoustic boarding on top of my existing plasterboard using green glue.

Which will be more effective? I am trying to mask neighbour noise (tv/talking/shouting), not building a music studio.

Can you point me to any specifications/statistics for each option in terms of effectiveness of the insulation method?

Thanks,

option A is your best bet for quality reduction.

Decoupling from the structure always delivers the best value...
