Safer field move
Pin liner panels at regular intervals with mechanical fasteners per SMACNA specifications — typically every 6" at edges and 12" in the field. Adhesive alone is insufficient, especially in high-velocity systems.
Ask Foreman
Can you verify this before I keep going? I’m looking at: Building a double-wall duct liner panel that shifts during assembly. What’s the approved correction for this job?

Do not hide, force, cover, or “make it work” if this affects safety, access, airflow, rated assemblies, supports, equipment, or inspection. Stop and verify the approved correction.
