Can you install rock wool insulation over EPS rigid foam boards?
I am replacing the windows and siding on my house built in 1994. The wall construction from interior to exterior is 1/2 " drywall, 2x3 strapping filled with fibergalss insulation, 6 mil vapor barrier, 2x6 wall with fiberglass insulation, 5/8 plywood, 2 1/2 " Type II EPS. Tyvek, siding. I intend to remove the EPS and install a self-adhering WRB on the plywood. Since I have the EPS will I create any problems if I re-install it and add 1 1/2" Rockwool Comfortboard 80 over the EPS?
