Vertical corner flashing & house wrap remains unclear on standard practice?
I see details for metal flashing integration with house wraps for horizontal areas (like windows). So…what about vertical areas?
What about metal corner flashing at an inside corner? Is metal flashing saving the housewrap (so over the house wrap) or is metal flashing the last line of defense if house wrap fails (metal flashing is behind the house wrap)?
My plan for today is multiple layers of integrating a new osb wall to existing brick wall:
1. prosoco joint filler on most outside of trim area to seal air channels created by mortor,
2. Siga Fentrim 6″ shaped on brick wall and osb wall,
3. 4″ metal L mechanically nailed, then edges zip taped to Siga on both sides,
4. house wrap with appropriate taping vertical
More than needed, but anything specifically wrong?
