Trim Thickness With Hardie Panel and Batten Siding
I will be doing a Hardie panel board and batten siding for my garage. If I use the 3/4 inch Hardie battens over 5/16 inch panels, that adds up to 17/16 inch thickness. That will stand proud of the 5/4 (one inch) trim by 1/16 inch. Am I missing something or is this the way it is? Does it matter?

bsandersga,
The 5/4 trim is going where? Around windows and doors?
Yes, windows, doors corners, water table.
bsandersga,
It only matters aesthetically. It usually looks better if the trim is deeper than the siding.
You have a couple of alternatives I can think of:
- You can back the trim with 1/4" plywood.
- Or more typical is to mount the trim on top of the Hardi-panels - and then use Hardi-Trim if you want.
I just discovered that Miratec trim
comes in a 1 1/4 thickness, so that might be the solution.
Allura and the old version of LP also have the same issue, I just learned today while shopping for B&B at Menards. LP shows how to go around this in a Youtube video, they cut a strip of the panel to put behind the header, then header trim, then Z-bar above the header trim, then you put the panel over the Zbar and flush with the window sides. Lastly, you put the 5/4 trim around the whole window. if you don't cut the strip to go behind the header trim, you can't properly install the Z flashing above the header. New version of LP changed the thicknesses so that batten + panel are less than thickness of 5/4 trim. I plan to do the strip behind the header trim.
