MasterFormat Division 07: Thermal and Moisture Protection

Division 07 covers the building envelope—waterproofing, insulation, roofing, siding, membrane systems, fireproofing, and sealants that protect the building from water, air, heat, and fire. Learn how Division 07 organizes specification sections, connects to UniFormat and OmniClass, and how The Construction Standard provides licensed access to authoritative, edition-aware Division 07 data through CSI Dynamic Standards.

MasterFormat Division 07 organizes the specification sections, cost codes, and work results for thermal and moisture protection across the construction industry. As part of CSI's consensus-based classification system, Division 07 provides the authoritative structure that specifiers, estimators, contractors, and software platforms use to organize thermal and moisture protection work.

What Division 07 Covers

Division 07 covers the building envelope—waterproofing, insulation, roofing, siding, membrane systems, fireproofing, and sealants that protect the building from water, air, heat, and fire.

This division includes dampproofing and waterproofing, thermal insulation, vapor retarders, air barriers, steep-slope roofing, low-slope roofing, wall panels and siding, roof specialties, joint protection, and fire and smoke protection.

Division 07 contains multiple levels of sections and subsections that organize this scope into a precise, consensus-based hierarchy. These sections provide the numbering backbone for project manuals, bid packages, cost databases, and BIM models. When teams reference Division 07 consistently, every document from concept estimate to closeout speaks the same language.

Licensed through The Construction Standard, CSI Dynamic Standards includes the authoritative, always-current section numbers and titles for Division 07—searchable, cross-referenced, and edition-aware.

Who Uses Division 07
  • Building envelope consultants
  • Roofing and waterproofing contractors
  • Energy modelers evaluating insulation assemblies
  • Architects specifying exterior wall systems

Whether you write specifications, estimate costs, coordinate BIM models, or build software that references thermal and moisture protection, Division 07 numbers and titles are the shared vocabulary your work depends on.

How Division 07 Connects to Other Standards

UniFormat

Division 07 maps to UniFormat B20 (Exterior Enclosure) and B30 (Roofing)—the envelope elements that Division 07 products and work results create.

OmniClass

OmniClass Table 23 (Products) classifies insulation, membranes, sealants, and roofing materials; Table 22 (Work Results) covers installation.

These cross-references are maintained by CSI through governed crosswalks—not assembled ad hoc by individual project teams. Through The Construction Standard, licensed access to CSI Dynamic Standards gives teams these relationships so they can navigate between specifications, elements, and lifecycle categories without manual remapping.

Why Edition Awareness Matters

MasterFormat evolves through consensus-based updates. Projects that span multiple years may reference different editions. Division 07 sections may be added, renumbered, or revised between editions. Without edition awareness, teams risk referencing obsolete section numbers, creating specification conflicts, and generating RFIs that delay construction.

Licensed through The Construction Standard, CSI Dynamic Standards gives teams full edition context for Division 07—teams know which edition applies at each project milestone, what changed, and where those changes affect their work.

The Licensing Relationship

CSI—the Construction Specifications Institute—stewards Division 07 as part of MasterFormat. CSI Dynamic Standards includes MasterFormat, UniFormat, and OmniClass as a connected, edition-aware system. The Construction Standard provides licensed access to CSI Dynamic Standards:

  • Always current: Section numbers and titles reflect the latest CSI-approved updates
  • Edition-aware: Teams know which edition applies and what changed between releases
  • Cross-referenced: Governed relationships to UniFormat and OmniClass stay maintained
  • Integration-ready: Enterprise solutions carry Division 07 data into the tools you already use
COMMON QUESTIONS
Division 07 – Thermal and Moisture Protection covers this division includes dampproofing and waterproofing, thermal insulation, vapor retarders, air barriers, steep-slope roofing, low-slope roofing, wall panels and siding, roof specialties, joint protection, and fire and smoke protection. It provides the authoritative section numbering used in project manuals, cost databases, bid packages, and BIM models across the construction industry.
Building envelope consultants, Roofing and waterproofing contractors, Energy modelers evaluating insulation assemblies, Architects specifying exterior wall systems—anyone who writes specifications, estimates costs, manages submittals, or builds software that references thermal and moisture protection work results needs authoritative Division 07 section numbers and titles.
Division 07 maps to UniFormat B20 (Exterior Enclosure) and B30 (Roofing)—the envelope elements that Division 07 products and work results create. OmniClass Table 23 (Products) classifies insulation, membranes, sealants, and roofing materials; Table 22 (Work Results) covers installation. CSI Dynamic Standards includes these governed crosswalks—licensed through The Construction Standard—so teams can navigate between standards without manual remapping.
If your organization uses Division 07 section numbers, titles, or descriptions in deliverables, templates, products, or platforms that others rely on, CSI Standards licensing is necessary. The license ensures you're working with authoritative, CSI-approved data that stays current with consensus-based updates.
