Smoke doors

Smoke doors with S-label.

Assemblies tested for air leakage, for corridors, smoke barriers, smoke partitions and elevator lobbies.

  • Air leakage max. 3.0 cfm/sq ft (UL 1784)
  • Listed smoke gasketing at head and jambs
  • Installation per NFPA 105, no louvers
LABELS-LABELcloser

Where codes ask for UL 1784

  • Corridor doors and doors in smoke barriers rated 20 minutes
  • Doors in smoke partitions
  • Elevator lobby doors
  • Areas of refuge and certain healthcare openings

What the S-label assumes

  • The listed gasketing is installed as tested
  • The door is self-closing and latches
  • Clearances stay within the listing
  • No louvers or field cut-outs

How we supply rated doors

  • Every fire-rated door we supply is built and labeled by a manufacturer that holds the listing for that door with a nationally recognized testing laboratory, such as UL or Intertek (Warnock Hersey), and is inspected under the lab's follow-up service.
  • The label is applied at the factory. We never apply, move or replace fire labels, and we do not field-label.
  • We take your door schedule and hardware schedule, check each opening against the listing, and have doors factory-machined for your hinges, locks, closers and electrified hardware.
  • Matching non-rated doors in the same veneer, paint or laminate come from the same order, so a corridor looks the same whether a door is rated or not.
  • Documentation for submittals and closeout: listing references, label type per opening, hardware compatibility and installation instructions.

Questions

Frequently asked.

Is weatherstripping enough for an S-label?

No. The S-label is only valid with the gasketing named in the listing, tested at room and elevated temperature.

Do all fire doors need an S-label?

No. NFPA 80 itself does not limit air leakage. The requirement comes from the specific code section for the location, such as corridors or smoke barriers.

Can a smoke door also be a fire door?

Yes, and most are: a 20-minute door with S-label covers both requirements in one assembly.

Code summary for orientation, based on the International Building Code (IBC), NFPA 80, NFPA 105 and the 2010 ADA Standards. Requirements depend on the code edition your jurisdiction has adopted and on local amendments. The architect of record and the authority having jurisdiction (AHJ) decide for your project.
