The insulation material on site does not match the project spec

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.

Do not substitute insulation, tape, adhesive, or vapor-barrier material because it looks close enough.

Check

Photograph the material label/roll/box.
Pull the relevant spec/submittal if available.
Compare type, thickness, facing/vapor barrier, and listed use.
Check whether access/labels/dampers will remain usable.
Ask foreman before installing.
