Air Barrier Continuity Inspection

It covers the visible continuity of the air barrier before the wall, roof, or ceiling assembly is covered. The template walks through readiness, continuity, tape and sealant detailing, penetrations, and blower-door closeout. It is meant to document observable deficiencies such as gaps, unsealed transitions, and damaged membrane laps. It does not replace a full envelope commissioning plan or a structural inspection.

Use it after the air barrier materials are installed but before enclosure concealment, insulation cover-up, or finish installation. It is especially useful before blower-door testing so obvious defects can be corrected first. If the work is phased, run it at each area or elevation as it becomes ready. Waiting until after cover-up usually turns a small detailing issue into a costly rework item.

A superintendent, quality manager, envelope inspector, or competent person familiar with the air barrier assembly can run it. The person should understand the approved details, product limitations, and how transitions are supposed to be sealed. On complex projects, the inspector should coordinate with the installer and the design team when a condition is outside the standard detail. The key is that the reviewer can distinguish a minor cosmetic issue from a true continuity defect.

No. This template is a pre-test visual inspection that prepares the area for blower-door testing and reduces avoidable failures. Blower-door testing measures performance, while this inspection checks the workmanship and detailing that support that performance. Using both together gives you a clearer path from field condition to corrective action. If the template shows repeated deficiencies, the test result is likely to reflect them.

The most common issues are incomplete tape adhesion, unsealed membrane laps, missed corners, and penetrations that were cut but not fully sealed. Inspectors also find fasteners or attachments that interrupt continuity, surface contamination that prevents adhesion, and rough openings that were not detailed to the approved design. Another frequent problem is assuming a visible bead of sealant means the joint is actually continuous. This template helps document those conditions in a consistent way.

It supports quality control practices used on projects governed by building codes, energy codes, and envelope performance requirements. The inspection approach is consistent with industry expectations for documented field verification, coordination of penetrations, and pre-cover review. Depending on the project, it may also support manufacturer installation requirements and third-party commissioning or envelope testing protocols. Always compare the field condition to the approved drawings and specifications for the project.

Yes. You can tailor the checklist to include specific membrane types, transition details, window rough openings, slab edges, or roof-to-wall interfaces. If your project uses multiple assemblies, add section notes for each condition so inspectors know what detail to verify. You can also add project-specific hold points, photo requirements, or sign-off fields. The template is intended to be adapted to the approved envelope design, not used as a one-size-fits-all checklist.

Document the location, the condition observed, and the affected detail before the area is covered. Capture photos that show both the defect and enough context to identify the assembly and elevation. Then assign corrective action to the responsible trade and re-inspect the repaired condition before closeout. If the issue affects a critical transition or penetration, treat it as a hold point until the fix is verified.
