Hey John,
I was on hardie website the other day trying to get a good hold of exactly how I want to do it. They have a download on best practices.
The question I always have is where do I put the Z-flashing. Originally I was planning on putting the foam right to the window opening. Then put window trim on top. Does the flashing go above the window trim and on top of the foam? Doesn it go under the foam? I really started chasing my tail on that one.
Finally I decided that the foam would not go under the window trim. I will just put on some thick window trim and the z flashing can go on top of that. I'm doing it like this. Just like what I found in the hardie best practices.
