Elite Duct Testing provides independent third-party Quality Insulation Installation (QII) field verification for Title 24 projects across Northern California, including the Bay Area, Greater Sacramento, and Modesto regions.

QII verification commonly involves a pre-insulation air-sealing inspection and an insulation inspection before drywall or other finishes conceal the work.

Quality Insulation Installation, commonly called QII inspection, is a Title 24 field-verification measure used on qualifying projects. The specific measures required are shown in the project’s approved energy documents.

In many projects, required air-sealing details must be verified after rough work is complete and before insulation is installed. This helps identify gaps and penetrations while they are still accessible.

After insulation is installed, QII verification confirms that insulation and applicable air-sealing details remain visible, accessible, and consistent with the approved energy documents. Schedule this visit before drywall is installed.

• Required air-sealing details before insulation, when applicable
• Insulation type and required R-value
• Full insulation coverage and proper fit within cavities
• Gaps, voids, compression, or missing insulation
• Insulation installed in contact with the appropriate air barrier
