party wall noise

[brummie]

any idea how much to supply and install those special wall boards that will keep the muppets music from next door coming into our lounge ?

"Our party wall solutions start from just �175!" is the claim on this site: http://www.soundstop.co.uk/
Even if you choose another supplier, the site has loads of information which should be of use to you.

Hoping this helps,
