What do I do when not protecting insulation from sharp wire/cable tray?

Insulation, Liner, Vapor Barrier & Condensation.1 field-polished — insulation/rated-detail check

Wire, cable tray, sharp edges, and other trades can cut vapor barrier after the wrap is complete. Protect or reroute before damage becomes hidden.

Field checklist

Look for sharp contact points near insulation.
Check if another trade is resting on or rubbing the wrap.
Document damage and ask who owns repair/protection.
Do not disturb another trade's work unless directed.

Ask foreman

This cable/edge is cutting into the insulation. Do you want protection added or coordination with that trade?

Do not

Do not ignore sharp contact because the duct itself is fine.

Why it matters

Insulation affects access, vapor barrier, condensation control, inspections, TAB/service access, and finished-work quality. Project specs and manufacturer details still control.
