I'm studying Rod's book with regards to MSM wall construction, and have a query with regards to location of the mass in a MSM wall construction.
My situation is that I live on a large rural property in the Southern Tablelands of NSW, and I have access to an 8m x 8m space inside a newly erected colourbond(steel) shed with concrete floor and 5m pitched roofline. I'm hoping to build a couple of room within rooms inside for a control room and tracking room (private use). Neighbours/noise are not an issue (we are in the middle of 250 acres), however I do wish to isolate the room structures properly from the steel exterior so that rain noise and metal expansion noises during changing weather do not dictate when I can record.
Ideally, I would wish to build a free standing wall structure just inside (but not attached to the metal sheeting of the shed walls) that would consist of, firstly 100mm insulation lining directly to the interior of the colour bond metal walls, then 16mm drywall or plywood>insulated studs>airgap>insulated studs>16mm plywood with 2nd layer of 16mm drywall (being the interior of the room).
I doubt the metal wall would be considered a mass layer?
The problem I have is that being on the farm (just my wife and myself) I can foresee a problem in building the frame for the exterior part of the wall on the floor, attaching the one or 2 layers of 16mm drywall, and then raising it myself - the weight would simply be too heavy for an 8m wall length some 4-5 metres high.
To cut back to the question, could I take an alternate approach by erecting the first wall of 2x4 studs against the insulated layer of the colour bond metal wall (not touching it) then applying a couple of layers of 16mm drywall to it, then leaving an air gap, then insulated 2x4 studs and finally another 2 x 16mm drywall layers, i.e. insulated studs>drywall layers>airgap>insulated studs>drywall layers. Would this compromise the performance significantly given my modest needs?
Thanks for any advice.
PS with regards the actual studio layout, I am quite keen to model the design that Rod goes into some detail with in his book in Chapter 10 "Putting It All Together" (figure 10.5 studio layout)
