I'm looking into choosing the siding for a new construction and I'm finding that blogs and websites seem to be suggesting batt & board is better than horizontal siding (e.g. vinyl, hardiplank, etc) for shedding rain water.
This seems counter intuitive:
- In horizontal siding, gravity would be pulling the water away from the seams. In vertical siding, gravity would be pulling the water along the seams.
- I would expect some amount of warping/twisting in either setup (or at least expansion/contraction with the heat of the day), which would seem to affect the vertical siding more. If horizontal siding sags, twists, or separates 1/4" from the piece above or below it, no problem, right? If a batt separates 1/4" from the board, I wouldn't be surprised if water gets sucked into the crack from surface tension.
I think I must be missing something, either in one of my above assumptions or in a lack of understanding of batt & board construction.

batt and board siding vs horizontal siding:
- "One downside to horizontal siding, in terms of durability, is the potential for rainwater to leak underneath the siding strips. This risk is relatively high, especially if you opt for wooden siding panels that will warp over time and can lead to mold and mildew growth, as well as expensive water damage. Vertical siding panels have far fewer instances of this kind of water damage, because any water that hits the surface of the panels drops immediately to the ground." https://modernize.com/home-ideas/33834/choosing-between-vertical-and-horizontal-siding
- "For starters, horizontal siding can be less durable than vertical siding. That's because it's more prone to water damage over time." https://www.exteriormedics.com/blog/picking-sides-vertical-versus-horizontal-siding-installation
