In an environment with a lot of moisture would vertical corrugated metal siding need furring strips?

RAUL33 | Posted in Green Building Techniques on

building a house in Houston, and will be installing vertical corrugated siding.
from the design phase I had planned to use furring strips to hold siding off tyvek house wrap. but now that i’m about to install i’m thinking the furring strips would not be of any use. if anything it seems they might even hinder air/water from moving vertically behind panels. because of this i am considering using cor-a-vent as furring strips but again i’m just curious if this expense and extra step will be helpful at all.
thanks in advance for your input.

    If the metal siding is truly corrugated, with an old-fashioned sine wave pattern, it will drain well without an additional rainscreen gap.

    If it is a flat panel with occasional bumps, it will benefit from the rainscreen gap.

    Another possibility, you can buy corrugated plastic in 4x8 sheets and make your own version of CorAVent. HD lists 4x8 Coroplast at $20 each.
