Insulation question - Barricade Wall Panels

[Stefan S]

I have an attached 25 x 13 garage that I am insulating and heating to 50°F when not in use.

Three of the four walls are 10" concrete with the back and side being below grade and the other side is a shared wall with what will be finished space.

Because the garage is already pretty small I am leaning away from a traditional 2"rigid foam and 2 x 4 studded wall as that will narrow the garage at least 6" (or a foot - see question below).

Closed cell spray foam is an option as well and one that I am considering but then you have wood in close proximity to the concrete and the associated chance of mold - I could space the wall off the concrete and allow spray foam in behind the backside of the stud but then you have a thicker wall.

The option I'm leaning towards is a Barricade wall panel that is 2.5" thick with OSB already attached. See www.ovrx.com for more info on what I am talking about. It offers an R12 and is a vapor barrier as well.

Questions:
1. Has anyone used these or have first/second hand impressions?
2. Am I overlooking another technology?
3. Pros and cons

related:
I am planning to insulate the two below grade walls with this system and on the side abutting finished space insulate on the finished side with traditional studding and spray foam. Is that the correct procedure?

At what cost? Versus what?
I see overpriced gimmick- in something that could easily be accomplished cheaper with other methods. And considering that the garage is a one car size- does a few less inches really make that much difference in the grand scheme of things- like money$$$$?

you could glue rigid foam on the walls

then frame up the walls with 2x3's

install electrical now (or wait and do electrical in conduit on outside of osb.)

then fill in cavities with rigid foam

then sheath with osb

paint

game over

All good questions thank you for responding - This is a case where a lot of toys and activities are stuffed in a one car garage so the three inches does make a difference when I am trying to get between the motorcycle and car.

THe cost difference isn't that bad especially when considering the time and fuel saved over driving to Lumber yard. I ran the numbers on the long wall for comparison.

Traditional building techniques with an r13 rigid foam board and PT bottom plate run about $540 without factoring glue, seam tape, drywall compound and hardware. It would actually be cheaper to have closed cell spray foam done in the traditional studding if I use an old estimate of $1.00 for a 12"x12"x1" area.

Barricade would be $670 plus hardware (it's about $52 a panel) so for 130 bucks I save a lot of time and get a thinner result provided it holds up as well or better than a traditional studded wall.

Apparently you can get the panels for 39.99 but shipping is expensive
