Timber frame for block wall

[enigma27]

Hi All.

Need a bit of advise.

I am having a garage conversion done and will be framing the internals and plasterboarding it.. Because this will be a cinema room and I will be installing in wall speakers I have decided to use 90mm stud timer to give me the required deapth to install them.

My question is becuase the timber is 90mm is the right way of securing the frame by actually securing a sole plate to the floor and header plate to the ceiling joists and then securing the uprights to both?

only reason I as is that most videos online that show how to stud frame a wall only maybe use 40-60mm timber and they show securing the uprights directly to the wall with no sole plate or header plate..

One other question if you were to look at an item that says it requires 90mm deapth requirements from the front of the wall then 90mm stud plus the 12.5mm plaster board should mean it will have enough clearence.. I am assuming they mean from the front edge of the plasterbaord which is where the frames for the speakers grip to.

Battening out a house for plasterboard - screw battens to wall, screw plasterboard to battens.

But for a cinema room I'd imagine you'd want a wall isolated from the garage wall (ie sound isolation), so you'd want a room within a room, using sole/header plate construction. And you could do this with 50mm battens and just leave an inch gap to the garage wall.

(use a plumb bob to get the plates to line up)

90mm depth requirements from the front of the wall

I'd have expected them to quote the depth of the unit, plasterboard comes in different thickness's and they'll have no idea what you are using

Also make sure to run a strip of DPC below the sole plate and anything in contact with concrete. Use treated timber, or better still galvanised metal stud work. Not that much more expensive and won't warp like timber.

Thanks Guys.

The concrete floor as it is now is being raised up to the same height of the house before its worked on and i believe a DPC is being incorporated into that.
