Perform a Final Air-Sealing and Insulation Quality Inspection

A. Finished-Project Specification

Deliverable: one completed final inspection record covering air-sealing continuity, insulation depth and fit, ventilation clearance, vapor-control continuity, duct-adjacent thermal control, and attic-hatch condition across the entire assigned structure, plus a resolved deficiency list and a formal approved, conditional, or rejected thermal-envelope readiness decision.

B. Assembly Inspection Schedule

Assembly	Governing Chapter	Primary Check
Framing-joint air seals	Chapter 3	Continuity and adhesion at plates, corners, and doubled framing
Service penetration seals	Chapter 4	Continuity, movement allowance, and preserved service access
Attic bypasses and chases	Chapter 5	Closure of chases, soffits, and partition tops with heat clearances intact
Attic baffles and ventilation	Chapter 6	Continuous soffit-to-attic air channel above insulation level
Wall cavity insulation	Chapters 7–8	Full-depth contact, no compression, correct fit around services
Window and door perimeters	Chapter 9	Continuous seal with preserved operation and drainage
Attic insulation	Chapters 10–11	Depth, distribution, product quantity, and protected access
Floor and crawlspace insulation	Chapter 12	Support, moisture protection, and full-cavity continuity
Rim-joist air seal and insulation	Chapter 13	Foam protection, termite gaps, and service access
Rigid-foam panels	Chapter 14	Seams, fasteners, edges, penetrations, and fire protection
Vapor-control layer	Chapter 15	Continuity, approved location, and no unintended double barrier
Duct-adjacent enclosure work	Chapter 16	Preserved duct insulation, drainage, and service access
Attic hatch or access cover	Chapter 17	Fit, insulation, and perimeter seal

C. Acceptance Standards

Check	Standard
Assembly coverage	Every assembly in the Assembly Inspection Schedule is inspected against its governing chapter's acceptance standard
Sampling	Depth or cavity measurements recorded at the required sampling locations, not a single convenient point
Access preservation	Junction boxes, valves, dampers, cleanouts, filters, and equipment remain accessible after all prior chapters' work
Clearance and airflow	Insulation does not contact prohibited heat sources and does not block required ventilation airflow
Deficiency resolution	Every recorded deficiency is corrected using its governing chapter's method and reinspected before final sign-off
Readiness decision	A single approved, conditional, or rejected status is issued and supported by the completed deficiency list and reinspection record

D. Preparation — Records and Prerequisite Confirmation

1. Assemble approved plans, insulation schedule, air-barrier details, vapor-control details, product records, photographs, and prior inspection reports. Confirm every Chapter 1–18 record is present before beginning; note any missing document and its source.
2. Confirm that plumbing, electrical, HVAC, fireblocking, and required rough inspections are complete. Record the inspection dates and approving authority for each.
3. Verify that all bulk-water and moisture problems have been corrected and dried. Cross-reference every Chapter 18 finding and confirm its correction and drying confirmation are on file.

E. Air-Sealing and Bypass Inspection

1. Inspect framing-joint air seals for continuity and adhesion. Walk the assigned framing joints and confirm no pinholes, skips, or uncured product remain.
2. Inspect plumbing, electrical, duct, and mechanical penetration seals. Confirm continuity, correct material selection, and preserved movement allowance at each.
3. Inspect attic bypass closures, chase blocking, and heat-source clearances. Confirm backing is supported, edges are sealed, and clearance dams remain intact.
4. Inspect baffles, soffit ventilation, insulation dams, and attic access. Confirm the air channel from soffit intake to attic space remains open and unobstructed.

F. Cavity, Opening, and Attic Insulation Inspection

1. Inspect fiberglass and mineral-wool cavities for full depth, edge contact, splits around wiring, fit around boxes, and absence of compression. Sample a representative set of cavities across the assigned wall areas.
2. Inspect window and door perimeter insulation while operating the units. Confirm continuous seal, unblocked drainage, and normal operation through a full open-close-latch cycle.
3. Inspect loose-fill attic depth, distribution, product quantity, and protected access. Record depth readings at the required sampling grid and compare to the approved target.
4. Inspect floor and crawlspace insulation for support, moisture protection, and continuity. Confirm supports are intact and no insulation contacts standing moisture or exposed soil improperly.

G. Rim, Rigid-Foam, Vapor, and Mechanical Interface Inspection

1. Inspect rim-joist seals, foam protection, termite gaps, and service access. Confirm foam edges are sealed and required termite-inspection gaps remain visible.
2. Inspect rigid-foam panel seams, fasteners, edges, penetrations, and fire protection. Confirm tape adhesion, fastener seating, and any required protective covering are complete.
3. Inspect vapor-control continuity and verify approved location. Confirm seams are lapped and sealed as specified and that no unapproved double vapor barrier has been created.
4. Inspect duct-adjacent thermal control and preserved mechanical access. Confirm duct insulation thickness has not been reduced and that filters, dampers, and condensate drains remain reachable.
5. Inspect the attic hatch for fit, insulation, and perimeter seal. Close the hatch and confirm full-perimeter weatherstripping compression.

H. Access, Clearance, and Testing

1. Verify that junction boxes, valves, dampers, cleanouts, filters, and equipment remain accessible. Physically confirm reachability rather than relying on prior chapter notes alone.
2. Verify that insulation does not contact prohibited heat sources and does not block required airflow. Check every recessed light, flue, chimney, and exhaust clearance zone identified in earlier chapters.
3. Record depth or cavity measurements at the required sampling locations. Log each reading against its location on the inspection worksheet.
4. Perform blower-door, infrared, smoke, or other performance testing only under the approved test plan. Record test conditions, results, and any documented limitation of the method.

I. Deficiency Resolution and Readiness Decision

1. Prepare a deficiency list with location, condition, required correction, responsible party, and reinspection method. Assign each deficiency to its governing chapter's correction method.
2. Correct or assign every deficiency. Confirm each correction is completed by the responsible party using the correct governing method.
3. Reinspect completed corrections. Repeat the specific check that originally identified each deficiency.
4. Photograph final concealed conditions. Capture a labeled photograph of every assembly type before it is concealed.
5. Issue approved, conditional, or rejected thermal-envelope readiness status. State the decision explicitly, along with any conditions that must be met before concealment.
6. Preserve records for the drywall handoff. File the complete inspection record, deficiency list, corrections, photographs, and test results for Book 11.
