7 Sapphire is having a series of soundproofing treatments. The walls is
just one of several treatments being installed. Other treatment are being
applied to cupboards and doors, alongside a specialist treatment for the loft.
Soundproofing the Living, Dining and Front room party walls
Downstairs, the walls are being covered with 20mm of soundproofing rubber
matting followed by 2 layers of Gyproc Soundproofing boards. Specialised
adhesives and filler are being used. We also need tenants to help by NOT
placing speakers against the wall and definitely NEVER nailing or screwing
anything into the wall!
Here is a link to the specialist supplier:
||A large stack of M20 specialist soundproofing mats. On at a
time each is coated with a specialist impact adhesive, which itself
complies with all Soundproofing standards. The wall is also coated
with the same adhesive and allowed to go "tacky".
|The tile has to be pressed into place, with less than 10mm gap on
any edge. A specialist caulk will be used to fill the gaps in
order to maintain the integrity of the sound "barrier".
||Tiles go from floor to ceiling
|The whole of the chimney breast is covered - sound travels up and
down the chimney breast with little muting and thus can be heard in all
connected rooms. In semi-detached houses, this can be a real
issue, especially if one or both have open chimney breasts
||After a lot of work, the whole of the party-wall in the living room
has been covered and caulked. It is left for five days for the
adhesive to harden before "sound-board" is put on.
|Two layers (see picture) of Gyproc Sound-Board are attached using the same
specialised adhesive and filler. Avoiding the use of screws helps to maintain
the integrity of the treatment.
A word of warning - this is very heavy work and not for DIY'ers or
anyone on their own...a definite 2-person job and both must be very
strong. Naturally, you will need qualified trades-people for
electrical and gas fittings. In this room, British Gas capped off
the Gas supply to the wall fitted heater that was in the room and our
local Electrician sorted out the wall-sockets.
The choice of this treatment will mean that 80% of most sounds will
be blocked in either direction. And the cost...well, the Living,
Dining and Front rooms cost around £3k and there is more to do upstairs.
