Zone 5 metal stud wall with rigid
I have a project with metal stud walls, gyp. sheathing, weather barrier and R10 EPS rigid in the cavity. Then R10.1 closed cell spray foam in the stud space. Brick exterior.
Part of the team calls for a normal, permeable weather barrier. Part of the team wants an impermeable Permabarrier…either ok with the insulation setup?
