We have started building our home and have 2 inches of exterior Rockwool going on in a week or so. It seems from what I read innies are the best option with a Rockwool. My wife and I would prefer outies and my builder has given us an option for outie window using a built out ledge for the window to sit on from the rough opening. They then plan to use the furring strips for the window flanges on the sides. They also want to use two layers of Tyvek, one between sheathing and Rockwool and one on top of the furring strips that will be used for the water control layer attached to the water control layer of the window. Thoughts on this?
