John Sayers' Recording Studio Design Forum

Ahamdulillah ,

thanx,....man(Stuart/soundman), really good to clarify almost........in my country , gypsum boards available are...12mm ,9mm and 6mm...so i gues its 12mm dual layers...right?
/
can it be done by hanging insulation or just by say stack of glasswool(70kg/qm)?

....now this time..by couple layers ...u mean outer leaf of the new ceiling right?
i have a question? ...lol..should the new ceilings of both rooms share common air gap from the old ceiling or need to be partitioned?......im sending the pic of new ceiling idea ...
.....in the pic
the are heights of A,B,C,D,E,M are alright? or need to increase?
should the L and O studs needs to be touched to the old concrete ceiling as for partition the old ceiling ? or leave as it is?....sorry for asking so many questions.......

Insaa Allah , Now that im pulling off the floor studs and putting laminating the floor ....my room height will be increased..say almost 10 feet ...... can u guys help with the ceiling? is my plan is alright?
are the points A,B,C,D,E,M heights ok? or need to be changed? .....do i need to put plywood under the original ceiling wall?

salam ,
@stuart, can u confirm me one thing ? do i need 2 layers of gypsum(12mm available) only the outer leafs of the adjacent walls or outer leafs of all the side walls and ceiling?.no one is
understanding the green glue over the shop as i tried does it have another name? ...what type glue material is this?

I would use thicker gypsum board, more like 15mm.

Green Glue is not glue! The name is confusing. You cannot use it to stick things together. It is not an adhesive. It is a special acoustic compound, used to improve isolation, especially low frequency isolation.

green glue is not available in my country ,searched almost every where ,...... is there any alternative?gypsum most thick is 12mm available here.

OK, if you can't get Green Glue, then just add one extra layer of drywall to each leaf. It will give you kind of similar results.

And if you can't get thick drywall, then maybe consider using thick wood: can you get 15 mm plywood, or 15 mm MDF, or 15 mm OSB? Or even better, 18 mm? If so, then use those.

salam ,
the outer leaf of the each room is already done before by the layers of drywall.now, i have both drywall(12mm)...and plywood 18 mm, rooms to be filled with inner leaf : live room and control
room

----for inner leaf, should i use ply or drywall or combination of both and for which room beside the slats?....should i use resilient channel?
----for the new ceiling, the double layers is on the outer or inner leaf?.........

Salam ,
The reason I'm asking again someone just told me the plywood for inner leaf
Can be reflective for vernised.so, I'm confused. Should I use it at live or control room? And
how?
