Most exterior foam boarding is per code. It does not have the same structural sheer strength as OSB or Ply wood.

  • Additional strapping is required to bring to code.
  • If hurricanes are common you should consider a upgrading.

Also in my experience taped seams don't always stay taped. It is always a good idea to use a house wrap that has far fewer seams.
