Garage Stud Wall

[Pilgrim_Mark]

Hello,
I have decided to try and build a stud wall perimeter inside my double garage to better use it as a home workshop.
I have zero experience in this, just basic woodworking skills.

My intended outcome of this is was;
A) A clean consistent look that I can use for storage / Cabinets / French cleats etc. for my workshop
B) Soundproof
C) Temperature control

I have read various forums, comments and watch some YouTube tutorials, but I would appreciate any advice you have for me on the following questions I have just before I begin.

1. Does the attached design generally look ok, Is there an unnecessary layer or an obvious omission?
2. Do I need to add a specific vapour barrier (red highlight on diagram A)? Or will the foiled PIR be sufficient.
3. I don’t currently have an air gap. Is this a mistake?
4. Is it better to build the stud frame on the floor then lift into position (where possible), or is it ok to build-in-place as it’s a bit fiddly?
5. If I do build-in-place, do I just attach the DPM directly to the concrete wall first, using Christmas Clips etc? If I build on floor, I presume I can just staple to rear side of the frame before lifting.

Thank you in advance for any help.
Mark

You don't need DPC at the ceiling abutment. You do need a continuous layer of insulation ACROSS the studs though. The diagram below shows a stud partition section separating a garage from a (habitable) utility room...

We also foil tape the PIR as to create a VCL.

Thank you Noseall.
1) DPC : of course, makes sense that you would not need for Top Plate. Thanks
2) It looks like you are using a thinner secondary PIR Celotex in front of the studs to create a continuous layer if I understand correctly.

Yes - 100mm between studs - 50mm across. Both layers foil taped.
