Wrong duct wrap around fire-rated assembly

Rated assemblies require the approved/listed wrap or protection detail. Normal duct wrap is not a substitute for a rated system.

Stop if

• This looks like rated duct wrap or a rated assembly. Can you verify the approved detail before we install or cover it?

Watch out

• Do not substitute standard duct wrap for rated assembly material.

Check

• Stop and identify whether this is a rated wall, shaft, grease, smoke, or fire-resistance condition.
• Find the approved detail/submittal before wrapping.
• Verify seams, overlaps, bands, access, and labels match the listed method.
• Get foreman/AHJ direction before changing material.
