We upgraded to have soundcheck plaster & batts to our theatre room but at lock-up noticed they haven't put soundcheck plaster on the ceiling! Upon looking at our tender we notice it says 'to walls' - there is no mention of 'ceiling'......so they haven't done it!!! Can you believe it!
Make sure you check and double check everything!!!!

My builder only installed the soundcheck plaster in the walls, and the heavy sound batts in the 2 interior walls. Nothing in the ceiling.
Didn't bother me too much at the time, but if I knew then what I know now (that my son's bedroom is partially above my theatre) I would have asked for at least the batts between the ceiling and the partial floor above. The plaster I possibly still wouldn't have bothered with as I was more interested in something a little denser to mount my in-wall speakers into at the time.
What's above the ceiling of your theatre?

Its a single story house so nothing is above the room. I'm annoyed though because we paid $1,000 for sound check plaster and acoustic batts and assumed this would have included the ceiling in the room. Obviously we were wrong.

Soundchek only spans 450mm - ceiling joists/ trusses are spaced at 600mm.
Using soundchek on the ceiling requires extra ceiling joists/trimmers to suit which means more dollars than the price difference of the gyprock.

Soundchek plaster sheets are the same size as a standard sheet!
Makes no difference at all

I know the sheet sizes - I'm talking about the span between studs/ceiling joists etc
The sheets you use on the ceiling are different to the sheets you use on the wall. Normal wallboard sheets will only span 450mm when used on a ceiling - a different type of sheet is used for the ceiling.

Then they just cut the joins to the underside of the truss...
My studs are 600mm apart my trusses are 600mm apart.
The only difference I see with the sheets is that both edges were bevelled on the ceiling sheets...

Its got nothing to do with the joins or sheet sizes Matt !!- its the ability of the board to span the 600mm distance between the bottom of the trusses - Soundchek will not span that. That is why thay didn't use it on the ceilings.

Ahh I see...
Because of the extra weight you need more points to hold it up alt and level!
I am with you now!

Not exactly more points, the board is denser and therefore will not sag in between the 600mmm span. Before 10mm ceiling gyprock was bought onto the market, all ceilings were sheeted in 13mm gyprock.
The main plasterboard manufacturers have tables on their websites with wall and ceiling spans for each product.
