What to Check First

Verify liner type, thickness, and orientation
Use the approved adhesive and coverage
Confirm pin type, length, spacing, and washers
Seal or coat exposed liner edges where required
Inspect for bubbles, loose corners, and damaged facing

Do Not Do This

Do not rely on adhesive alone when pins are required, guess pin spacing, use short pins, or leave exposed loose edges in the airstream.

Why This Matters

Loose liner can delaminate, restrict airflow, contaminate the system, and become impossible to repair after installation.

Verify against: approved liner submittal, manufacturer installation instructions, project specification.
