New construction in CZ3 (southeastern NC).
2×6 exterior walls @ 24″ OC with 7/16″ vertical ZIP sheathing. NO exterior foam.
Hardie fiber cement lap siding.
Dense pack cellulose in the walls.
Wrap around porch covering the entire front and one side of the house.
Average about 55″ rainfall per year.
I’m assuming a rainscreen would be a good idea in my situation. Furring strips vs drainage mats/mesh? Is one method considered best?
Also, if using 3/4″ thick furring, would that affect my window and door details the same way using exterior foam would? The siding would be 3/4″ further out from the sheathing, windows, and doors, so I wasn’t sure about the affect on the flashing details. Thoughts and experiences?
