WRB on porch columns and beams
Currently wrapping up installation of the WRB (no pun intended) on new construction, and debating how to treat the covered porch. All of the new construction that I see around here (zone 5), the structural porch columns and beams are all wrapped and taped tight with house wrap prior to covering with cladding. Intuitively, it seems to me like wrapping the beams in particular (or beneath any vertical surface for that matter) is dangerous because of the potential for trapping water. I have searched extensively but haven’t been able to find any information about this. Any WRB tips for covered porches would be appreciated.
On a related note, Tyvek installation guidelines show a detail for wrapping the underside of a cantilever floor. This also seems dangerous without some way for water to escape. Maybe I’m overthinking this, but seems every discussion about water management emphasizes the rule that one should always assume water will find a way in and needs a way to escape. Is the WRB an exception to this rule?
Thanks in advance.
