I wanted to ask, for a future build of our house, with dedicated home theatre, what type of wall batts should I look at
to insulate the steel stud walls with? Would I be better with an accoustic dense type batt, or the pink batt stye?
I intend doubling up on the gyprock, and using a soundcheck/firecheck qyprock with possibe use of green glue in between,
but am usure of the insulation of the stud frame side of things.
Any advise will be greatfully appreciated.

I have found polystyrene sheets superior to the acoustic batts.

Soundscreen insulation batts are what I will be using for the HT Room, plus soundcheck gyprock.
As where you can get those types of Batts, Low-grade ones can be bought from Bunnings.

we're having acoustic batts in the theatre room walls. getting builder to put them in.
Wakeboardandy bought acoustic batts from bunnings for about $300 and installed them himself (with permission of builder). says someone sleeping in next room can't hear noise. sounds good to me!

Hi there Jarrod,
Hi mate. Don't pretend to know everything about soundproofing but I do know that the following is going to work best for you.
(1) Don't worry too much about spending all of the extra money on acoustic gyprock if you are contemplating using Green Glue.
(2) Standard fibreglass batts will offer very similar acoustical properties when used in conjunction with other soundproofing products like Green Glue and Green Glue Whisper Clips (recommended). Save your money and just use the cheaper fibreglass batts (R3.5's are fine and cheap these days).
(3) Look into using Whisper Clips. Made by Green Glue and very effective for reducing sound transmission.
(4) I would recommend R1.5 or R3.5 batts, Green Glue Whisper clips, 2 layers of 20mm gyprock (standard not acoustic) and Green Glue applied between. Use this method on all four walls and the ceiling. Plug up any windows if you can with double gyprock plugs and use an exterior grade solid core door with acoustical seal underneath (www.raven.com.au)
Happy to help if you need any more assistance. Not saying that the other products are a waste of money, but my understanding is that they will offer minimal performance return based on the dollars invested if you are looking at GG.

Nice sumary Greg. This thread points out an important thing. Insulation intuitively seems to be a very valuable thing, however it is actually only a small contributor to the larger soundproofing picture. People tend to assume great sound isolation value with insulation, however of the 4 elements of soundproofing, absorption (insulation) is the least contributive.
Foam panels are distinctly less beneficial than standard thermal fibre insulation. The moral of the story is that insulation has value, but there's no data that supports using anything beyond standard (not dense) fluffy insulation.
As a side note, I would do the math to look at three sheets of standard plasterboard vs. 2 sheets of specialty plasterboard. All you want is the mass. Could be 2 sheets of denser (expensive) board, three sheets of standard (inexpensive) board, or some combo. Mass is mass
