building a wall against an exterior wall
I have done a complete gut and plan on building a hollow wall directly against an exterior wall. The reason I am doing this is that this wall is going to have my tv on it and have all my av gear against it. I want a hollow wall so that I can channel wires/cables and leave future options.

My exterior wall is now insulated and vapour barriered and I had planned on building the wall up against that. A friend of mine came over and suggested that I first drywall the exterior wall so as to further seal it prior to building my hollow interior wall (which will also be drywalled). I do not see the point of this but this is why I am asking here.

Hope I explained this well enough.

Drywall will seal the exterior from the interior
My last house they did not seal the drywall behind the kitchen cabinets
There was cold air coming in from all around the cabinets

I would definitely drywall & mudd to seal the drywall
Since it will not be seen it doesn't have ot be all that pretty
But keep it as smooth as possible

How big will the new wall be?
Most of my AV/audio stuff needs 12-15" depth

I am not looking to do a built in for the gear. I am just doing a 2 x 4 wall right against the exterior wall for channeling wires up and down from the tv...unseen. This also leaves me the option of installing inwalls if I ever decide to do that.
