Renovating and installing new cement board
Installing new cement board. Insulation is 1/2-inch blue XPS.
Barriers go under insulation or over? Hardie / CertainTeed contradict each other.
Also, can I get certain types of material that I should use?
I'm in Foxboro, Mass.
1/2" XPS is due to 3/4-inch window allowance, with getting into additional trim thickness.
Tape all seams in insulation and in barrier?
