GARAGE DESIGN USING A MIXTURE OF PLANS

There seems to be problem with many of your images: they are not showing up properly. Maybe you could edit your post to fix that, as it's hard to see what you are explaining in the text.
Yes, that is a problem! Even one single nail or screw bridging across the gap is plenty good enough to destroy your isolation.The roof of this is pitched and one section of it is slightly touching the existing garage joists. 1. Is this a major concern? If yes, would It be better for me to Essentially, use the vocal booth as a stand alone stud wall as per new sketchups?
Right. That makes sense.2. So the vocal booth and stud walls attached to them become the outer leaf and the inner leaf remains completely decoupled from it?
You would just build a frame across there that does NOT touch the booth at all, and then you'd need two doors: one on the new frame, and one on the vocal booth.3. If this is the way to do it, how would the stud walls walls attached to the vocal booth need to be constructed? would it be as per diagram "walls" and
Not sure: you'd have to check your local building code to find out. It depends on the climate, and should usually go on the side of the wall cavity that is warmer in winter.4. Is the vapor barrier in the correct place?
I can't see which part is "highlighted in red", since your images are not showing up, but yes you do need insulation in all the cavities between leaves. - Stuart -5. Also, does the joists section above the vocal booth need to be filled with rock wool? See diagram new walls 2 the area highlighted in red?
Hi Stuart,
That's really strange as I can see them fine on my laptop. I've amended them now so hopefully you can view the diagrams
thanks

Hi Guys,
Just a quick question regarding the vapour barrier. To save you looking through the old posts, this should give you an update.
Single detached brick garage 16 foot by 8 foot. Only ¾ of the garage will form the studio. Stud walls are now up which are 2 inches form the walls, new ceiling joists are inter leaved between the existing joists so the frame is completely decoupled from the existing structure (which the exception of the concrete floor). Stud walls have now been filled with 100mm Rockwool. Baffle boxes not yet installed but they will be once the plasterboard is up. The insulation has been up now for about 2 weeks as I have not yet had chance to put the vapour barrier up. The Rockwool on the ceiling has started to gather condensation. I have had the door open as much as possible to get some air moving in there but its not doing much.
Question 1 – can I continue to install the vapour barrier over the Rockwool whilst the condensation is still there or do I need to figure out how to completely dry it first?
Question 2 – building regs have not actually specified a specific vapour barrier, they said I just need one. Can anyone recommend one. I’m based in the UK.
Thanks
Get rid of the condensation first, for sure! Yes, in theory it could leave through the walls over time, but it's impossible to say how long that "time" would be, and you certainly do not want to trap high humidity inside your walls. So get a good dehumidifier going in there full-time and keep the door closed until the humidity is under control, the condensation is gone, and the insulation is totally dry: Then put up your vapor barrier.Question 1 – can I continue to install the vapour barrier over the Rockwool whilst the condensation is still there or do I need to figure out how to completely dry it first?
Check with local builders in your area to find out what they use, and how they install it. Normally, 6 mil polyethylene stabled to the studs just before you put the drywall on is fine, but check to make sure that is OK and legally acceptable where you live. One other thing: try to figure out for sure if it really is only condensation that you are dealing, and not something worse... Hopefully you don't have water infiltrating through the walls... You need to be 100% certain of that before you seal it up. - Stuart -Question 2 – building regs have not actually specified a specific vapour barrier, they said I just need one.
