Metdeck is the warm roof solution.
Installation with this warm roof system zinc plus standing seam can be installed on rigid insulation without ventilating the underside of the zinc plus.

The insulation in a warm deck roof is installed immediately below the roof membrane on top of the roof deck usually with a vapour control layer underneath the insulation.
