Do not assume airflow approval means the louver will pass architectural privacy or light-leak requirements.
Check
Stand on both sides and check direct line-of-sight light.
Confirm the room type and architectural/acoustic requirement.
Check required net free area before changing louver style.
Verify wall/fire rating if applicable.
Use an approved sight-proof/acoustic assembly, not a field-bent patch.

Say this to your foreman
The transfer louver at [location] passes light straight through into the room. Airflow may be okay, but it looks like the wrong blade style. Do you want a sight-proof/acoustic louver submittal checked?
