Detail or Installation Mismatch in Division 07 Thermal and Moisture Protection submittals

By Deviation Check Editorial Team. Last reviewed June 1, 2026.

Short answer

The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require. Default grade in Division 07 Thermal and Moisture Protection: Fix and Resubmit.

The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require. This guide covers how it shows up specifically in Division 07 Thermal and Moisture Protection submittals.

What to look for in Division 07 Thermal and Moisture Protection

  • Membrane thickness below manufacturer warranty minimum
  • Insulation board thickness or layering sequence differs
  • Lap width or seam method (heat weld vs adhesive vs tape vs liquid-applied)
  • Flashing termination detail (reglet vs surface-mount counterflashing, termination bar)
  • Roof drain type or size differs
  • Fastening pattern (mechanically attached vs fully adhered vs ballasted)
  • Attachment method for insulation (adhesive vs mechanical vs both)
  • Fireproofing thickness differs from UL listed assembly requirement
  • Firestop system configuration differs from tested/listed assembly (UL/WHI)
  • Sealant joint width-to-depth ratio outside manufacturer recommendations
  • Vapor retarder location in wall/roof assembly (warm side vs wrong side)
  • Air barrier continuity detail at transitions (wall-to-roof, wall-to-foundation)
  • Metal panel attachment clip type or spacing differs

How severe is it?

Default grade: Fix and Resubmit. Escalates to Blocker when the difference affects a fire-rated, seismic, or structural assembly.

Deviation Check assigns a default per category and escalates or de-escalates based on the spec, always showing its reasoning. See the Division 07 severity rules.

What the PM should do

Stamp the submittal Revise and Resubmit. Mark the deviation, return the relevant spec passage as a redline, and have the sub correct and re-send before fabrication or installation.

Frequently asked questions

What lap width and seam method differences are reviewed in Division 07 Thermal and Moisture Protection submittals?

Submitted details must match the spec on lap width and seam method - heat weld, adhesive, tape, or liquid-applied are not interchangeable without approval. Fastening pattern also matters: mechanically attached, fully adhered, and ballasted systems have different wind uplift performance and warranty requirements. Membrane thickness below the manufacturer warranty minimum is a separate flag that often appears alongside a seam or attachment discrepancy.

How does vapor retarder placement affect a detail mismatch finding in Division 07 Thermal and Moisture Protection submittals?

Vapor retarder location on the wrong side of the assembly - the cold side instead of the warm side - can cause condensation within the assembly and is flagged as a Fix and Resubmit. Air barrier continuity at transitions such as wall-to-roof and wall-to-foundation must also match the specified detail. When the mismatch involves a firestop system configuration that differs from the tested and listed UL or WHI assembly, the finding escalates to a Blocker.
