Corrugated metal over mineral wool
Hi, I am looking for ideas for installing vertical corrugated metal over Roxul comfort board.
A bit more about the project:
2×6 @ 24″ OC walls insulated with Roxul batts (R-23),
plywood, wrb, and
2″ Roxul Comfortboard (R-8), corrugated metal siding running vertically.
Do I need to install vertical furring a layer of horizontal furring to attach the corrugated panels to? Can the metal be attached directly over the comfortboard?
Thanks for any thoughts/ ideas.
