Hello everybody!!!Love this forum, been reading it for months like a tv serie :) planing and searching etc...first let me thank you all and specially John i don't know even where to begin...
location: Stockholm / Sweden
Type of room: Basement
Dimensions: Room size: W:6m L:6.60m H:2.40m
Status: under construction
Budget: 2500-3000 USD
Goals: 1 control room/Mixing room, 1 Recording room
Music Style: all Genre
Design: Sketch Fennec 1.1
problems: there are many water pipes hanging in the middle of the room which i cant touch or change are already isolated
I just finished framing the room
Walls: existing concrete walls /10 cm air gap / wood stud 45mm by 95mm filled with insulation 70mm/ OSB 12mm
Ceiling: existing Concrete ceiling/6 cm air gap/ wood stud 45mm by 70mm filled with insulation 70mm/ OSB 12 mm
Questions
1- Is my design ok?
2- After the osb should i use the RC + 13mm gyps/green glue/13mm gyps ? or directly to the gyps without the RC?
best regards
Fennec

Hi Fennec.
Please check the forum rules: you are missing something... :)
and also:/ OSB 12mm
12mm and 13mm materials are too thin: (too flexible, too high resonant frequency, too low mass, etc.) You should only use 16mm or greater.13mm gyps/green glue/13mm gyps
If you put RC in there, you will have a 3-leaf system with a very thin air gap! Bad idea! Just put the drywall directly on the OSB. Question: Why do you have the OSB there? Is there a reason why you could not just put the drywall directly on the studs/joists? - Stuart -2- After the osb should i use the RC + 13mm gyps/green glue/13mm gyps ? or directly to the gyps without the RC?
Hi Stuart, thank you so much for the replay
please correct me if i am wrong i am taking it one step at the time , i have been reading the forum rules and i really thought i am following apology if i missed something
i guess its about the music genre well all genre means all loudness from filmmusic to heavy metal from acoustic to electric with live drums etc...
when it come to isolation its a basement there is a sushi bar above :) so i need to isolate the rooms from external sounds which mainly they come from the ceiling.
-yes agreed the drywall of 13mm are too thin that's why i though i add OSB sheet to beefup 12+13+13 = 38mm
would it be better if i add a layer of drywall at the end ?
concrete /10cm air gap/insulation/osb 12mm/drywall 13mm/drywal 13mm/green glue/drywall 13mm
mass + air + mass!
cheers Fennec
I think he means although your location is in the content of the first post, you need to put it in your profile.

Yup! That was it! :)I think he means although your location is in the content of the first post, you need to put it in your profile.
That still doesn't change the thickness of each INDIVIDUAL sheet! Yes, for MSM purposes you only take into account the total mass on each leaf, and that's it. But the individual sheets of whatever makes up that "mass" still also behave as individual sheets, as well as behaving as a single chunk of mass. So thin springy flexible light-weight drywall reacts to things that thick rigid heavy drywall doesn't react to. In other words, even though your total mass is the same in both cases, the effect won't be the same. Think of it this way: you could make up the same amount of mass by stacking a few old newspapers, a layer of bubble-plastic, some tin sheeting, some copper foil, a piece of carpet, some cardboard, a thin pane of glass, and a thin sheet of wood veneer. Obviously, that bunch would not react the same way as if you made up the same amount of mass from a single sheet of steel plate, or a layer of concrete. Each material has its own characteristics that affect the sum total, in one way or another. There's the issue of stiffness, for example, and the issue of coincidence dip. So in general, thin, light, flexible things are not so good for isolation. If that were my wall / ceiling, I'd much rather go with two layers of 16 mm drywall than 3 layers of 12 mm, despite the extra mass in the former. - Stuart -yes agreed the drywall of 13mm are too thin that's why i though i add OSB sheet to beefup 12+13+13 = 38mm
agreed Stuart !
the fact is that i already ordered 60 sheet of dry wall 3.6m*2.4m 13 mm because was cost effective the 16mm dry wall is Sweden costs the triple of what costs the 13 mm :( any other alternative ?
Have a look at Fermacell ! :wink:
Same deal here in Switzerland. 15mm drywall was a rediculous price compared to 12.5mm
Fermacell, which in many places is more expensive than firecode drywall was priced here at what I more or less had expected to pay for 16mm drywall.
Not too sure how available it is in Sweden.
