Fire-rated assemblies: documentation checklist
A documentation checklist for fire-rated assemblies: listings, test reports, penetrations, firestops, doors, inspection records and handover.
A fire rating is only as good as the documentation and installation behind it. Rated assemblies are tested as complete systems, so a missing board layer or an unsealed penetration can void the result. This checklist focuses on what to request, collect and keep, so inspectors, insurers and future owners can see what was built.
Understand what is rated
Fire resistance is tested under standards such as ASTM E119 for building construction and materials, and penetrations and joints are tested under related methods such as ASTM E814 (also published as UL 1479) for through-penetration firestops. Listings cite the tested design: framing, spacing, board type and thickness, fasteners, insulation, and joint treatment. Product claims like "fire resistant" on a data sheet do not equal a rating. Always request the listing or report number and compare it with the built assembly.
Document checklist by element
| Element | Request and keep |
|---|---|
| Walls and floors/ceilings | Listing design number, board type and layers, framing details, insulation, joint treatment, fastener schedule |
| Fire doors and frames | Label or certificate, listing, hardware list, gaps, installation to NFPA 80 as adopted locally |
| Through-penetration firestops | System listing number, product data, installer, location log, photos before cover |
| Joint systems (head-of-wall, expansion) | Listing, movement class, product and installation record |
| Fire dampers and smoke control | Product listing, installation instructions, test and acceptance records |
| Coatings and intumescent products | Product listing, thickness records, applicator records |
| Fire-rated glazing | Label, listing, frame requirements |
The table is a general checklist. Requirements depend on the project, occupancy and local rules.
Penetrations and joints are where ratings fail
Most defects found in inspections are unsealed penetrations, wrong firestop products for the pipe type, and gaps at the top of walls. Each service penetration needs a listed system matching the wall type, penetrant material and size. Keep a penetration log with location, listed system number, installer and date, and take photos before concealed areas close. When another trade later adds a penetration, the firestop system must be restored and logged. Link with the sealants checklist for compatible sealants at joints.
Doors and hardware
Fire door assemblies include the leaf, frame, glazing, hardware, closers and seals, and are normally labeled. Field modification, such as cutting new hardware preps without permission, can void the label. Check gaps at head, jambs and bottom against the allowed values, and confirm self-closing and latching. See exterior doors and interior doors for procurement.
- Label visible and legible on each door and frame.
- Hardware is listed for use on fire doors.
- No unapproved holes, vents or kick-plate modifications.
- Closers adjusted and functioning.
- Smoke seals and gasketing installed where required.
Inspection, testing and handover
- Agree an inspection plan with the designer and the local authority before work starts.
- Inspect framing and first-layer boards before the second layer and insulation hide them.
- Inspect penetrations and joints before concealment.
- Record deviations and corrections with dates and photos.
- Compile a handover binder or digital file organized by floor and location.
- Provide maintenance guidance for doors, dampers and sealed joints to the owner.
Where third-party special inspection of firestop or fire-resistive materials is required by code, schedule it early; failed inspections delay occupancy.
Boundaries and responsibility
This page is a documentation guide and not a statement that any assembly complies with a code. Fire ratings, listed designs and approvals must be selected and confirmed by the designer or fire protection engineer, and accepted by the local authority. Do not change a listed assembly without written approval.
Template for a handover index
A tidy index makes later inspections and renovations far easier. Organize the file by floor and room, with columns for element type, listing or system number, product, installer, installation date, inspection date, photo reference and notes. Add a section for service changes after handover so new penetrations are logged. Share the index with the owner, the facility manager and the insurer if requested, and store it where it survives staff changes.
Use clear scans or photos, and keep the original listing documents with their dates, since listings can be revised over time.
Questions people ask
What is a fire-rated assembly?
A wall, floor, ceiling, door or other element tested and listed to resist fire for a stated time under a defined test, with specific materials and details.
Where do I find a listed assembly?
Listing directories from certification bodies such as UL and similar organizations publish designs with the exact materials and construction required.
Can I change a listed detail on site?
Not without approval. Changes can invalidate the listing. Get engineering judgment or an approved alternative from the designer and the local authority.
What records should I keep?
Listing numbers, product data, installation photos, inspection reports for penetrations and joints, and door and damper certificates, organized by location.
