When used on the interior of a metal building which side should face the exterior metal sheathing of the building? Plywood or drywall interior cover?


Hi Mike, It does not matter. Normally, I would apply the silver side towards the exterior for a radiant barrier and yes plywood or drywall can be used as the interior cover.
