# Performance Specification Gap in Division 07 Thermal and Moisture Protection submittals

> Source: https://deviationcheck.com/divisions/07-thermal-moisture-protection/performance-specification-gap/

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

## What to look for in Division 07 Thermal and Moisture Protection

Key performance parameters in Div 07 submittals:
- **R-value** per inch and total assembly thermal resistance (per ASHRAE 90.1 / IECC)
- **Wind uplift rating** (FM 1-60, 1-90, 1-120, 1-150, 1-180 or UL 580 classification)
- **Fire rating** (ASTM E119 hours for fireproofing, UL fire resistance assembly listing)
- **Flame spread / smoke development** (ASTM E84 Class A/B/C, NFPA 285 for wall assemblies)
- **Water vapor permeance** (perms per ASTM E96, vapor barrier vs vapor retarder classification)
- **Air leakage rate** (cfm/sf at 1.57 psf per ASTM E2357 for air barriers)
- **Membrane thickness** (mils for single-ply, plies for built-up/modified bitumen)
- **Peel adhesion** (pli for self-adhered membranes)
- **Elongation percentage** (ASTM D412 for elastomeric membranes)
- **Tensile strength** (psi for membranes)
- **Shore A hardness** (for sealants)
- **Joint movement capability** (+/- % for sealants)
- **STC (Sound Transmission Class)** for assembly (where specified)
- **Fireproofing density** (pcf for sprayed fireproofing)
- **Fireproofing thickness** per UL assembly listing and structural member size

## Severity

Default grade: Blocker. Always a Blocker when the gap touches life-safety or structural performance.
