CSI Division 07 Thermal and Moisture Protection: section numbers and submittal deviations
What gets flagged between a Division 07 Thermal and Moisture Protection spec section and the submittal package, why it matters, and how each deviation is graded, so you can catch it before you send the package or before you approve it.
Short answer
Thermal and Moisture Protection is Division 07 in CSI MasterFormat, so its section numbers start with 07. Common sections include 07 11 00 Dampproofing, 07 13 00 Sheet Waterproofing, and 07 14 00 Fluid-Applied Waterproofing. Its submittals deviate most often on product substitutions, performance ratings, and missing certifications.
Division 07 covers thermal and moisture protection systems in commercial construction: waterproofing, insulation, air/vapor barriers, roofing, flashing, fireproofing, firestopping, and joint sealants. Common CSI sections submitted for review:

The six deviation categories in Division 07 Thermal and Moisture Protection
Every issue Deviation Check flags maps to one of six categories. Here is how each appears in Division 07 Thermal and Moisture Protection submittals, with the full guide one click away.
Manufacturer or Product Substitution
Blocker The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request.
Div 07 specs routinely name roofing system manufacturers, waterproofing producers, and insulation brands. Look for:
Manufacturer or Product Substitution in Division 07 Thermal and Moisture Protection submittals →
Performance Specification Gap
Blocker A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

Missing Certification or Compliance Documentation
Fix and Resubmit A required listing, test report, certification, or compliance document is absent from the submittal package.
Required certifications in Div 07 submittals:
Aesthetic Deviation
Fix and Resubmit A visible attribute (color, finish, texture, profile) differs from the spec or the architect-approved sample.

Detail or Installation Mismatch
Fix and Resubmit The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require.

Submittal Package Incompleteness
Fix and Resubmit A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted.

How Division 07 deviations are graded
Each finding is graded Blocker, Fix and Resubmit, or Note. Division 07 escalation rules:
- R-value below ASHRAE 90.1 or IECC minimum: BLOCKER (energy code violation)
- Missing FM or UL fire rating for roof assembly: BLOCKER (building code, insurance)
- Fireproofing thickness below UL listing requirement: BLOCKER (fire resistance compromised)
- Missing firestop UL/WHI listing: BLOCKER (life-safety, fire compartmentalization)
- Membrane thickness below manufacturer warranty minimum: BLOCKER (warranty void)
- NFPA 285 test missing for exterior wall with combustible components: BLOCKER (fire code)
- Wind uplift rating below design requirement: BLOCKER (structural/life-safety)
- Flame spread exceeds Class A where spec requires: BLOCKER (fire code)
- Air leakage rate exceeds spec maximum: FIX_AND_RESUBMIT (energy code)
- Sealant movement capability below joint design: FIX_AND_RESUBMIT (premature failure)
- Vapor retarder on wrong side of assembly: BLOCKER (condensation, structural damage)
- Roofing membrane color mismatch (affects SRI compliance): BLOCKER if cool roof required, FIX_AND_RESUBMIT if aesthetic only
- Missing installer certification: FIX_AND_RESUBMIT (warranty requirement)
Run a Division 07 submittal review
Upload a Division 07 spec section and your submittal package before you send it, and get a one-page deviation report in under five minutes, so the package goes through the first time. GC reviewers use it the same way on a package that just arrived. Before that, work through the free Division 07 checklist.
