Internal Wall sound insulation

    Hi All,

    I am currently renovating a room in a 3 bed semi and would like to put in some sound insulation on the partitoning wall to the adjoining house. I have the walls stripped and they need to be skimmed so I am thinking this would be a good time to do it. Can sound insulation boards be bought and fitted easily. Would a standard Kingspan board provide any kind of sound insulation?

    Any advice would be much appreciated.

    I just came across this:

    http://www.sealsdirect.co.uk/bbCMS/shopping.asp?intDepartmentId=9#61

    It's lead lined noise insulation material. The reason it is so expensive and heavy is because of the lead in it. I have read about this stuff somewhere but never had a supplier for it this side of the Atlantic.

    It is expensive, but if you are really concerned about noise, it's hard to beat lead.

    Kingspan's technical department should be able to advise you on whether their materials are suitable and how many db they are rated for.

    There is a bit more to sound insulation than just materials - you have to assemble everything so that there isn't too much of a bridge for the sound to cross.

    This has been covered here many times: google boards.ie for the key words you want using advanced search in google: ie in:
    Search within a site or domain: put boards.ie

    eg for Sound insulation

    http://www.google.ie/search?hl=en&as_q=&as_epq=sound+insulation&as_oq=&as_eq=&num=10&lr=&as_filetype=&ft=i&as_sitesearch=boards.ie&as_qdr=all&as_rights=&as_occt=any&cr=&as_nlo=&as_nhi=&safe=images

    the 2 key areas are the mass of the material{ hence lead) and airtightness

    Here are some general principles

    http://en.wikipedia.org/wiki/Sound_insulation

    Under the building regulations a 215mm wall built of sold blocks laid on the flat only achieved their maximum dbA sound reduction when plastered both sides and built using "full" bed and perpend joints - i.e. with no "Hollows" in the middle of the joint. You'd be surprised how much sound can come through and open joint.

    Also head into the attic and examine the top of the party wall. This should be sealed above and below the roofing felt in accordance with Part B fo the building regulations for fire separation purposes, but this also means you get good sound sealing. Check there are no blocks missing or unsealed penetrations for pipes.

    Finally take a good look at the room and windows. If you have a window vent near the neighbours open window when he's blaring out Beethoven the sound will come back into the room via the vent. Similarly, in older single glazed windows or timber windows that have warped, you don't get good sound insulation.
