What do I do when the insulation material on site does not match the spec?

Insulation, Liner, Vapor Barrier & Condensationred

Do not install insulation that does not match the drawing/spec/submittal. Document the staged material and ask before it becomes hidden work.

Open in Field Rescue Open category

Field checklist

Photograph the material label/box/roll and the area where it will be installed.
Pull the insulation schedule/spec note if available.
Compare material type, thickness, vapor barrier, facing, and special environment requirements.
Ask foreman/PM to verify before installing.

Ask foreman

The staged insulation looks different from the spec/submittal at [location]. Do you want this held until the material is verified?

Do not

Do not assume fiberglass wrap, elastomeric, liner, rated wrap, and vapor-barrier products are interchangeable.

Why it matters

Wrong insulation material can create condensation, failed inspection, failed spec compliance, or rework after cover.
