Hi
I've just got a new house, 1910 terrace, and as often seen the soundproofing for the party wall could be better. I can hear the neighbours talking!
So, I thought I's upgrade the soundproofing of the party wall in the bedrooms. In the alcoves either side of the fireplace, I'm thinking of putting in two stud walls (separated from the party wall by cm, so an airgap is present) 2x2 timber with rockwall inserted and plasterboard (soundboard?) on top. This is often posted as a way of upgrading the soundproofing - as chimneys are often well constructed, but the party walls are often a single brick and badly mortared - so the sound leaks through there. The house has solid brick external walls, and floorboards.
What I'm worried about is the alcove where one side is the chimney, the other the external wall. By creating a cavity (remember there stud wall is separated by a cm from the party wall) is there any risk of condensation occuring at the surface of the external wall (eventually causing damage). Or am I worrying too much about this?
What if I carefully seal it up plus use waterproof plasterboard?
The alternative would be to use gyproc tri-line instead - if this was installed correctly (i.e. properly sealed around the circumference of the board) would this be better? less risky then putting in the stud wall+ small cavity??
All help and advice gratefully received!
