What do I check for finish work: duct liner / sound lining at openings?

Finish Work, Punch List & CloseoutVerified starter — finish work field check

Lined duct and sound boots need clean opening details. Loose liner, torn edges, blocked airflow, or exposed fibers can create performance, cleanliness, and punch-list issues.

Open in Field Rescue Open category

Field checklist

Look inside opening for loose/frayed liner.
Keep liner from blocking airflow path or damper operation.
Make sure device/frame does not tear liner during install.
Report damaged liner before covering it.
Keep visible edges clean and secure per spec/detail.

Ask foreman

The liner at this opening is loose/damaged. Do you want it repaired before I install the grille/diffuser?

Do not

Stop if liner damage affects a return/supply opening, smoke/rated assembly, healthcare/clean area, or manufacturer/specified acoustic detail.

Why it matters

Finish work is where rough-in becomes visible, inspected, balanced, serviced, and turned over. Clean install and access matter.
