Performance objective
Recladding can expose opportunities and risks around continuity of the air-control layer at openings, transitions and penetrations.
Complete assembly
Performance belongs to the complete exterior-wall or building system, not one visible component.
Testing and engineering
Use current tested assemblies, evaluation reports and professional analysis where code/performance requires it.
Long-term behavior
Moisture, movement, coatings, joints and maintenance access should be planned over the service life.
Questions to resolve before approval
For air-barrier coordination in recladding, confirm the measurable scope, exact product/system basis, existing-condition assumptions, access and work-hour constraints, who owns adjacent work, required approvals, warranty/closeout expectations, and what will happen if field conditions differ from the bid assumptions.
Common budgeting mistake
A common mistake is to price air-barrier coordination in recladding as an isolated product purchase. The usable project cost usually includes interfaces, access, preparation, operations, project management and future service—not only the visible material or equipment.
