Rainscreens: minimum depth
On this forum, I’ve often read that, ideally at least, a rainscreen should consist of a gap no less than a 1/2” deep. This video calls that a “myth,” and claims that 1/4” is the minimum, that only a gap less than 1/4” would be too small. What are folks’ opinions on this? (For the room I’m building, I’ll see if I can get away with 3/8”; knowing that even 1/4” is acceptable, of course, would make me feel much better about that.)
The video covers other “myths,” including the claim that you need an insect barrier. Personally, I don’t buy his argument; not adding a barrier seems too risky to me.
