Flashing Details for Panel Siding
9aSApwW9w5
| Posted in GBA Pro Help on
I am wondering if anyone has any advice on properly flashing window and door penetrations when using a panel type siding. My specific project specifies LP Smartside reverse board and batten siding in 4×8 sheets. The windows and doors are aluminum clad, with a 1×4 picture frame trim detail.
I am mainly concerned about the detail at the head, where it should be flashed. I would like to avoid just cutting out a hole in the panel for the trimmed and flashed unit, then relying mainly on a caulk joint, but maybe properly detailed, this is the simplest option.
Thanks for any help.

Pete,
It's not clear from your question whether this is new construction or a window replacement job.
Do these windows have flanges?
This is for new construction and the windows are flanged.
Pete,
Your question is unclear. I don't know why you would depend on a caulk joint. You want metal Z-flashing at the head.
Here are some details from Hardie (see below). You can see more details at

Thank you, I had not seen that shim out detail before and seeing it drawn out now makes perfect sense.
