ZIP Window Detail with Exterior Insulation
On ZIP’s website, they have window details which appear to combine the flashing/window buck of an outie window, but it is shown flashing into a WRB (in this case the ZIP sheathing) located behind the exterior insulation.
Is there any reason this method cannot be employed with dealing with standard OSB and house wrap? I am planning a deep retrofit on our current home, and I would rather leave the WRB at the sheating, but outie windows seam easier. Can I install the window buck, flash the buck back into the WRB at the sheathing, then install my exterior insulation (in my case, Roxul Comfortboard due to the presence of poly on the interior of the wall.
