Comments on my wall and ceiling plan!!

Hi there, I have just compleated my live room wall and ceiling plan for my builder attached below. Any idea of the STC - acoustic drums and rock gtars will be recorded in this room. Any major faults/problems? Do you recomend I glue or srew the second layer of wall board. Thanks again

On the existing walls - the grey 10mm plasterboard - if you can tear that out - you'll get better soundproofing for the drums. If you can salvage some of it - put it between the studs to increase the mass of the outside layer & caulk it very well. Screw in the 2nd drywall layer

Hey Andrew, When you say caulk it very well... Do you mean at the edges of every wall or along the edges of each piece of sheetrock? Thanx man, TIK

Everything. Caulk every crack, gap & hole. Corners, between sheets, bottom, top, etc.

As Aaronw states - caulk everything. You cannot over caulk. For each layer - caulk the ceiling and floor and run caulk between the joins of every sheet. You'll use a lot of caulk and a lot of latex gloves! For the 1st layer I taped the joints also and put drywall mud over the whole sheet and especially on the joints.

Hi John, Is the whetherboard outside layer sealed. If not , then it is not acting as your mass leaf and you're better off leaving the 10mm plaster in there, provided that that's sealed (caulked) of course.. cheers

Thanx fellers, I am already on my third case of caulk... T[/list]
