QII (Quality Insulation Installation) Inspections
Quality Insulation Installation (QII) is a mandatory Title 24 verification for many newly constructed homes and additions across Northern California. As independent CHEERS-certified raters, Pacific Airflow inspects and documents wall, ceiling, and floor insulation at the framing stage — before drywall conceals the work — so your building envelope meets the energy model and your permit closes on the first pass.
California Title 24 requires QII verification by an independent rater with no financial tie to the insulation installer. Pacific Airflow provides 100% impartial inspections accepted by every municipal building department.
Independent QII Verification for Title 24 Compliance
Field studies consistently show that poorly installed insulation can cut a wall's real thermal performance by 30% or more — even when the labeled R-value is correct. Gaps, voids, and compressed batts let conditioned air escape and outside air in, undermining the efficiency the energy model assumes. Title 24's QII requirement closes that gap by requiring a certified rater to verify the actual installation.
Pacific Airflow performs certified Quality Insulation Installation inspections throughout Northern California. We inspect the insulation while the framing is still open, document every cavity with photographs, and upload the CF3R certificate to the CHEERS registry so your inspector has clean paperwork at final.
Our QII Inspection services include:
- Framing-stage (pre-drywall) insulation inspection
- Final insulation inspection after drywall and finishes
- Air-barrier contact and insulation alignment verification
- Gap, void, and compression detection across all cavities
- Electronic CF3R certificate upload to the CHEERS registry
When QII Inspections Are Required in Northern California
Title 24 calls for QII verification on many newly permitted projects. Here is when to schedule Pacific Airflow.
New Construction & Additions
Most newly constructed single-family homes and many room additions require QII when the energy model uses it as a compliance credit. Scheduling the framing-stage inspection early prevents drywall from closing in unverified insulation.
High-Performance & Envelope-Driven Projects
Projects relying on tight envelope performance — including those needing blower door testing — depend on correctly installed insulation to meet the air-leakage target. QII verifies the insulation that makes that performance possible.
Permit Closeouts & Final Sign-Off
The registered CF3R certificate must be in the inspector's hands before final. We schedule the framing inspection around your drywall date and upload results fast so a missing form never holds up occupancy.
What Our QII Inspectors Evaluate
A QII inspection is not a quick visual check. We verify the installation matches the compliance documents cavity by cavity, with special attention to the spots where errors most often hide.
Gaps, Voids & Compression
Missing insulation, cut-out voids around obstructions, and compressed batts cut real R-value. We flag each one while the wall is still open.
Air-Barrier Contact
Insulation must sit in full contact with its air barrier — usually the drywall or sheathing. Gaps behind the insulation create convective loops that drain efficiency.
