TinnerFlow™3rd YearGREEN · Standard CorrectionAcoustic Transfer Louver Light Leak
Airflow may be correct but the louver style may not meet the room privacy/acoustic need. Use the approved sight-proof/acoustic transfer louver type.
A straight-blade transfer louver can move air but still allow line-of-sight light through the wall. In conference rooms, projector rooms, studios, or privacy spaces, that can be a finish rejection even if airflow is fine.
Confirm the architectural/acoustic requirement, net free area, and wall rating. The likely fix is a chevron, sight-proof, or acoustic transfer louver assembly that blocks line-of-sight while keeping the required air path.
Do not assume airflow approval means the louver will pass architectural privacy or light-leak requirements.
Wrong louver style can pass air but still fail owner/architect punch.
Final direction belongs to the foreman, approved drawings/specs, manufacturer instructions, pressure/material schedule, employer policy, and AHJ/code requirements.
