PERSIST Workshop Wall Construction in Upstate NY (Zone 5A/6A)
I am going to break ground on a 24'x32' detached workshop in a month or two. I liked Martin's article on "Getting Insulation Out of Your Walls and Ceilings" enough that I am going to give the PERSIST technique a try with this workshop. Here is my wall detail.
It is slab on grade with radiant floor heat. The foundation is a block wall on a poured concrete footing. The foundation, walls, and roof are insulated with XPS foam. The walls are 2x4 stud walls with open stud bays. I can always add insulation in the stud bays later and drywall if I find I need it. It has a truss roof. The exterior finishes are vinyl siding and asphalt shingle. I am using "Ground Breaker" panels over the exterior foundation foam. I am planning a heat exchange ventilator to get fresh air in.
We were going to use 1x4 furring, but we are having trouble finding it in longer lengths at a reasonable cost. We will likely go to 2x4 instead of 1x4.
Please let me know your thoughts on the design. Also, please let me know if the drawing helps you.

Other Questions in Plans Review
Since drywall has a permeance of 0.02 liter/sec - m at 75 PA is ever possible to have sheathing dry to the interior of the home?
