Static field route #826What do I do when insulation installed before pressure test?
Insulation, Liner, Vapor Barrier & Condensation.1 field-polished — insulation/rated-detail check
Do not insulate before pressure testing or leakage checks when the job requires testing. Covering early makes leaks harder to find and fix.

Field checklist
- Confirm whether this system/zone requires pressure or leakage testing.
- Check that all required test sections are visible and accessible.
- Hold insulation until test or foreman release is complete.
- Photograph if cover approval is given.
Ask foreman
Is this section cleared for insulation, or does it need pressure/leakage testing first?
Do not
Do not wrap over joints that still need to be tested.
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.
