Sound Insulation to party wall to prevent noise transfer from 'slamming toilet seats'

ajfarrell

Hi Folks,

I've searched the threads for a problem I'm experiencing but cannot locate an exact solution.

The thread: http://www.boards.ie/vbulletin/showthread.php?t=2055643095 explains a good idea of simply build a 2x4 wall an inch from the party wall and put on 2 layers of plasterboard on your own side with "vibration dampening compound" between each layer, whilst leaving a 5mm gap all way around the new wall plaster boards, caulking the gap.

My problem is that the neighbouring apartment has both its toilets locating along my party wall length, so every time they go to toilet (and they go allot!) I am greeted by a very annoying toilet seat being slammed shut sound. It travels very wall into my room since toilets are fitted onto the party wall and the wall is a large area (4m high).

I'd appreciate any ideas/comments the community may have on solving this problem. I was thinking of constructing a new concrete wall, but the floor most probably isnt sized to take that extra load. So it would seem a new stud wall with 2 layers of plaster board on each side, each layer filled with compound, the cavity filled with high density rockwool, and skim finished?

Many thanks,

tred

Wonder would it be cheaper for you to buy them some self closing toilet seats!!! Not sure where you can get them...

I done a Job a number of years ago where the sound from a live music room was causing annoyance in the adjoining room. We took down the Wall rebuilt a cavity wall with a special sound proof Rockwool in the cavity as we built the second wall. Work out a brilliant success. So I'm sure what your proposing will work ok. But talk to the rockwool people. There in Ballymount Dublin 12 just of
O Mahony's roundabout. If you need there nane pm me.

Rockwool = Sound Absorption not sound insulation
The key thing that that happened here was that you increased the overall mass of the wall. The mineral wool minimised reflection of sound within the cavity. Rockwool/mineral wool in itself is not a sound insulator but is a valuable part of a good wall build-up.

you can buy soft close toilet seats in woodies /bq for 50euro each go talk to your neighbour at 100euro it is the cheap way to go

Your perfectly right the extra mass in the wall obviously played a part in the improvement. However the type of Rockwool used was a special sound absortion or sound proof material and I remember it cost something like 8 to 9 Thousand Euro about 25 Years ago. But as I said it was a great success.

:eek: I wonder what it would cost now.

I'd hate to think what it would cost. The wall was 3.5 meters high and about 25 meters wide. and it cost a total of 12 thousand for everything.
