We're building a new home in New Jersey. We're going to use James Hardie HardiePlank Lap Siding ("Smooth") for the exterior siding.
I've heard from a general contractor friend that it's best to use Tyvek "DrainWrap" (which has vertical ribs) when using fiber cement siding. The logic in doing so is to promote draining (because the ordinary "HomeWrap" product is a completely flat surface).
From the DrainWrap website:
"Tyvek® DrainWrap™ helps provide enhanced drainage behind claddings such as primed wood (all six sides), fiber cement siding, and foam board applied over flat substrates. Vertical grooves on the surface of Tyvek® DrainWrap™ make it a superior moisture barrier, engineered to channel bulk water away from wall systems and drain safely to the outside."
Has anyone used this "DrainWrap" product with James Hardie HardiePlank Lap Siding? If yes, what are your thoughts?
