Question How to make weather resistant T1-11 horizontal joints

Hi all-
I am building a barn and siding it with T1-11 but want to know how to make a good weather resistant horizontal seam (the 4' long butt joint) where I run the T1-11 over 8' tall....
Z-flashing would look bad and a bevel joint seems iffy...
Any ideas?

thanks in advance-

I tend to think that Z flashing looks a bit dodgy while installing it...but once it's up and painted the same as everything else, well, you can't see it from my den. It's really the best solution.

and if you think the Z flashing looks bad, draw a picture ( stickmen are allowed ) of yourself out there replacing the crappy stuff in a few years due to rot ......ahahahahaha

Even with the flashing, go look a some that has been up 5-10 years......that's the trouble point for most of it.

You can order pressure-treated T1-11. (As far as I know, it is still available for approx 30% more than untreated T1-11.)
Even so, I would still use the Z flashing.

Z flashing is required with T1-11 applications at the butt joints - at top of sheet. Without it you're just asking for trouble.

Any exterior paneling will require Z flashing.

Caulking should be applied at joint between top of z-flashing and bottom of sheet above.

Good luck!
