Should we use some type of housewrap or other barrier for SIP? – GreenBuildingAdvisor

We are using panel w, its basically the styrofoam and we plaster concrete on both sides

We will be using it for the roof as well, the roof will be flat as we will have a 2nd floor

So wondering if we should use any type of barrier?

My builder has used ICF, but not SIP, so i have been collecting information for him

We will be putting in an ERV

Climate is San Diego region, from about Nov to Feb there is a lot of rain
