Brick veneer inward vapor diffusion with exterior mineral wool

art_kiwacz | Posted in General Questions on

Heard some opinions that mineral wool will slow down inward brick veneer vapor diffusion causing build up of moisture in the cavity. This was the planned exterior wall.
Brick veneer – 1″ space – 1.5″ mineral wool – 38 perm rated wrb (mento 3000) – 1\2″ cdx – 2×6 with mineral wool – intello vapor retarder. 

Was thinking to forgo the exterior insulation altogether and have a bigger drying cavity between the brick and wrb. Any recommendations?
