### A single coordinating contractor shall be designated as responsible for maintaining the continuity of the air-and-water control plane at all transitions between envelope trades.
−### The coordinating contractor shall prepare and maintain the air-and-water control plane continuity coordination drawings required as an action submittal.
−
−### Each envelope trade shall coordinate its work with the adjacent trades so that the air barrier and water-resistive barrier are continuous across every transition and penetration.
−
−### The design shall declare which performance, air or water control, is required of which layer at each transition. {note}
−
−### The water-resistive barrier required by IBC Section 1403 controls liquid water infiltration; the air barrier required by the IECC controls bulk air leakage. A single product may serve both functions, but the two functions are not interchangeable, so no transition should rely on an unstated assumption about which layer does which job. {note}

## Exposed air barrier and membrane materials shall be covered by the subsequent layer within the manufacturer's published UV-exposure window.
−## Where cladding is delayed beyond the published UV-exposure window, the exposed membrane shall be covered or replaced as the manufacturer directs. {note}
+## Where cladding is delayed beyond the published UV-exposure window, the exposed membrane shall be covered or replaced as the manufacturer directs.
## Fluid-applied air barriers and self-adhered membranes carry UV-exposure windows that typically run from 30 to 180 days depending on the product; the window is tracked from the date of installation, not the date of inspection. {note}

## Exterior wall assemblies that contain foam plastic insulation on buildings over three stories shall be tested and listed to NFPA 285 as the complete as-designed assembly.
−## The NFPA 285 listing shall match the actual assembly used in the work, including the specific insulation, water-resistive barrier, and cladding; substitution of any combustible component requires re-verification against a listing for the substituted assembly. {note}

## No envelope layer shall be concealed by a subsequent layer until the concealed work has passed any inspection or test required for that stage by the field-test plan.
−## Substrates shall be inspected and accepted by the installer of each envelope material before that material is applied; commencement of installation constitutes acceptance of the substrate. {note}

## A coordinating warranty scope shall be established so that responsibility for water intrusion at the interface between two envelope systems is assigned to a defined party rather than disclaimed by both.
−## Premium membrane systems installed by a manufacturer-approved applicator may carry an extended manufacturer warranty; where an extended warranty is required, the installer qualification necessary to obtain it shall be specified accordingly. {note}
