UL 1784 Smoke-Rated Steel Framing Systems & Hardware

Precision-engineered slim-steel framing providing elite smoke-rated protection and modern aesthetics for high-traffic environments.

Ugly smoke doors are a thing of the past. Slim-steel profiles offer protection without compromising your design.

The Forster presto S-Label smoke-rated system delivers specialized life-safety protection for North American buildings, carrying Intertek listings and full certification to UL 1784 smoke standards. These narrow-profile steel assemblies are designed to maximize transparency while effectively containing smoke and draft in critical egress areas.

Each system features unique factory-installed hardware, including concealed hinges, concealed closers, and tubular exit devices that integrate seamlessly with advanced building access-control systems. To meet diverse project requirements, McGrory Glass offers versatile glazing options ranging from security and ballistic-resistant glass to decorative and switchable privacy glass. Every unit is supplied as a fully fabricated K/D assembly, ensuring precise fit and finish in a wide range of TGIC-free powder colors, brushed or polished stainless steel cladding.

Where are smoke doors typically found?

Common applications for smoke doors include: elevator lobbies for fire service access elevators and occupant evacuation elevators, corridor doors (especially corridor doors in health and wellness facilities where care recipient sleeping rooms are housed), smoke partitions (for example, in atriums or lobbies), underground buildings (such as subways and garages), health care facilities, ambulatory care facilities, exit enclosures/passageways, and more.

Each smoke door application can have specific hardware or gaskets required to meet different code section requirements.

What is the difference between a fire-rated door and a smoke door?

Both fire-rated door assembly systems and smoke door assembly systems are code-driven: meaning their design is determined by building codes designed to provide maximum safety to building occupants. McGrory Glass’ team can help you understand complex code requirements and design the best solution.

While fire doors can double as smoke doors, smoke doors may not meet the building codes prescribed for fire-rated assemblies. Certified smoke doors and fire doors must both be labeled accordingly and listed with recognized testing facilities such as UL or Intertek.

Overview:

• Smoke doors have a range of hardware and decorative options, as well as privacy and security variations

• Fire-rated doors and assembly systems stop the spread of both flames and smoke, and are available in fire-resistant systems that have temp rise performance and also provide a barrier to radiant heat

• Smoke-rated doors stop the spread of smoke only, and may be glazed with tempered or laminated glass that is not fire-rated, either protective or resistive
