I've normally come across plasterboard walls that have been skimmed. The
ones I'm looking at have just seen paint and/or wallpaper.
These are in a poor condition and was thinking of simply replacing the
lot. Removing wallpaper is taking away the paper on the board too.
This could also present the opportunity of adding sound / thermal
insulation into the studded walls. Currently there isn't any.
Any thoughts? I see even Wickes only charge £6.50 for a 8 x 4ft x 12.5mm

The sound is transmitted through the timber battens from one side to the ot

You could just overboard, and refit or replace the current skirting? I
did this on one wall, and joined the remaining with dry lining tape and
special 'skim paste', and it worked fairly well by my standards. Other
services (mainly heating, but also electrics) can complicate.
Won't work *as well* as decoupled/solid-mass type options.
If there are joins/gaps (say around switches, skirting and openings) in
the current arrangement that'll be plugged by wool, there will be an
appreciable difference. Also ceiling and floor voids.
Depends on what you mean by work. Mineral wool insulation *will* give a
reduction in sound transmission, although it will not be a total sound
block - and will not obstruct lower frequencies.
There are other things you can stuff walls with that will result in
better attenuation, without going to the effort of fully decoupling the
wall surface. (e.g. you can get a cork backed PIR foam insulation with
a bitumen face cover on the other side. They have a bit more density and
will block lower frequencies better than normal mineral wool)
If trying to reduce noise from a neighbouring property, then that might
be the best way to go. For just providing better isolation between rooms
that may well be overkill, especially since you will lose rooms space in
You may even find cheaper sources if you need multiple boards, but
generally PB is cheap.
Its an easy enough job to do, although don't underestimate the mess -
its difficult to get off full sheets of PB without breaking them up
quite a bit in the process. (easiest way I found was to cut them into
sections using a wall chaser in line with each stud. Then it basically
comes off in a 4x2' panel at a time).
Ideally you would want to skim the new wall if you want to avoid a
repeat of the process you are currently going through.

glass wool typically achieves the same db reduction with less than half
the mass. A deciding factor can sometimes be the secondary feature of a
product. For example, glass wool can also give far higher thermal
performances, which may also help to retain heat in certain zones when
partitioning between rooms in domestic housing. Glass wool is also often
considered easier to handle due to its weight and longer, less itchy and
I recently got some glass wool style insulation from B&Q that was made
from recycled material. A darker grey/brown colour that the normal
yellow glass wool. A pleasant surprise what that it was far nicer to
handle than the normal stuff - softer to the touch, and it did not leave
that itchy "impregnated with glass fibres" feeling you normally get if
you touch the stuff.
This was the one IIRC:
I think that article must come from the advertising dept!
I have been re-modelling a mid '90's timber frame chalet bungalow. The
original insulation is glass fibre and also fitted to internal studwork.

You can get plasterboard, such as Gyproc Soundbloc, which has a high
density core, to reduce noise transmission. It seems to cost about twice
the price of standard 12mm, so you could simply use two layers of 12mm,
with staggered joints, for about the same price. It obviously depends
how much noise you want to stop, but I have used 2 x 12mm as the outer
on a plasterboard wall of a fire compartment and the difference from a
standard plasterboard partition was noticeable.
