Rainscreen for Zone 4 (Virginia)?
We plan to use Hardieboard on a new-construction residence in southern Virginia. It will have “pretty-good” walls with Zip-R1.5 sheathing. Zip recommend a rain screen behind the siding, but does not require one.
We guesstimate it would cost $1500 (on a $500k project) to put in a basic rainscreen with a 1/4″ air gap.
What say you all? Would you do it?
