Zip R wall sheathing to Rockwool foundation insulation
Hi all – planning a new build – hoping to be net zero when all said and done. Have spent a lot of time researching exterior insulation options and bridging the exterior wall insulation (I plan to use Zip R 2inch – climate zone 4) and the exterior foundation insulation (likely use Rockwool comfortboard).
There doesn’t appear to be a great solution on finishing the Rockwool insulation. Has anyone thought of dropping the rain screen purlins from the Zip R over the Rockwool and utilize a versetta stone type product screwed into the purlins? This assembly assumes the zip R and Rockwool are on the same plane. I may need to wrap the purlins that drop down to grade in zip tape to prevent moisture wicking and premature rot?
Anyone tried something like this?
