I have a new one-story office building, slab on grade with footings at about 42".
Am looking to run continuous 2" rigid insulation on exterior of the sheathing and then essentially continue it right on down to the footing. This of course leave 8" or so exposed above grade, which then needs a cover board, or applied protection coating.
I like the simplicity of the idea of getting continuous insulation with no thermal bridging on the exterior, but the cover board thing sounds a little cheap-ish.
Any experience with the cover boards or applied protection coating in terms of durability and appearance?
