This is the answer to the question Is it possible to mount horizontal vinyl siding vertically?
Revision 1
In general, there is no direct prohibition on such installation. But there are a number of nuances that must be considered.
1. Vertical and horizontal installation must necessarily be separated, for example, J-profile. Otherwise, the water will get inside.
2. Some manufacturers have holes on the bottom of the panels for condensate drainage, and they will be visible if you install the panel vertically.
3. Ship beam and herringbone are not symmetrical profiles and may not turn out aesthetically.
As for warping. You can't over-tighten the screws and need to leave thermal gaps, and that again leads us to the J-profile at the bottom and top of the vertical "sticks", which will close those gaps
