I have a friend who needs some advice on a wall detail. The wall stacks up like so: .5″ gypsum wallboard, 2.25″ EPS, 8″ concrete, 2.25″ EPS, stucco scratch coat.
He hasn’t done the stucco yet and we’re wondering if he needs to add a rainscreen detail. It’s a new build but due to a family tragedy, he needs to finish it as quickly and cheaply as possible.
I’m not sure of the climate zone but it is in the B.C. interior, 5700 HDDs, and not too much rain.
