The insulation material on site does not match the project spec
Insulation, Liner, Wrap & Vapor Barrierred
Do not install questionable material and hope it passes. Document the staged material, compare it to the spec/submittal, and ask before anything gets wrapped or hidden.
Compare type, thickness, facing/vapor barrier, and listed use.
Check whether access/labels/dampers will remain usable.
Ask foreman before installing.
Ask foreman
The spec/submittal appears to call for [material], but the staged material is [material]. Do you want me to hold installation until this is verified?
Do not
Do not substitute insulation, tape, adhesive, or vapor-barrier material because it looks close enough.
Why it matters
Insulation is often inspected by material type, thickness, facing, continuity, and application. Wrong material can create rework after it is hidden.
