Also included are assemblies composed of concrete masonry and other components, including plaster and gypsum wallboard finishes, and multi-wythe masonry components including clay or shale masonry units. 1-Hour Fire Resistive Rated Wall Assemblies. It also acts as a heat sink, reducing the chance of fire on unexposed sides of the assembly. Concern about potential damage to building exteriors caused by high wind events such as hurricanes and tornadoes has spurred many states, including Florida and Texas, as well as the model codes to adopt regulations to increase resilience from windborne debris and the effects of high winds and static loads. One aspect of this protection is based on limiting the movement of fire and smoke through the building using a compartmentation approach (also called the fire area). Components within the assembly may include swinging doors (ZHCW), door frames (ZHDL), latching hardware (ZHEM), hinges (ZHDX) and other items, along with a description of the allowable wall constructions and, where applicable, the maximum impact energy resistance and maximum design pressure. UL Fire-Rated | Westbrook Concrete Block Plaster and stucco are applied in accordance with the provisions of the building code without further modification. . The calculated fire resistance rating information presented here is based on the IBC and ACI/TMS 216.1 (refs. Fire-protection Rated Glazing Materials (KCMZ) are intended for use in fire windows, fire doors and fire door frames with transoms and/or sidelights that are provided with suitable glazing frame members. When the Listing Mark of UL is stamped into the frame, one of the following abbreviated product identities may be used: FDF in lieu of Fire Door Frame Exit doors are intended for use in applications where model codes allow power operated sliding or swinging doors, such as those installed in supermarkets. You are leaving the UL Solutions website for an external site. Frequently Asked Questions | Fire-Rated Assemblies - National Gypsum (51 mm). You are leaving the UL Solutions website for an external site. Openings in the roof shall not be located within 4 feet (1220 mm) of the fire wall. 2-Hour Exterior Wall Assembly - UL Design No. It also includes requirements designed to limit the movement of smoke through the building using smoke barriers and partitions. Our solutions also help confirm the safety, performance, reliability and security of your fire-resistant rated designs. While finishes are normally applied for architectural reasons, they can also provide additional fire resistance. A UL fire resistant rated ceiling also provides a known, specified fire resistance period. UL Solutions structures this activity to be distinct and separate from its conformity assessment bodies. These include the following: UL certifications UL certifies the following products for use with doors serving a buildings means of egress system. While test methods such as ASTM E119 define procedures for evaluating the fire resistance properties of concrete masonry assemblies, including those constructed using unconventional constituent materials, there has historically been no defined procedure for applying the results of ASTM E119 testing to standardized calculation procedures available through ACI/TMS 216.1. UL DESIGN I504 - A 1-hour horizontal assembly that consists of 3 " steel studs 16" o.c. The means of egress is intended to provide a continuous and unobstructed path of travel from any occupied portion of a building or structure to a public way. Explore our press releases and news updates. Model codes include requirements for doors which serve the means of egress system, which are referred to as exit (egress) doors. Fire window frames are Listed for a 3/4 hour or 1-hour fire rating. Glazing materials may be provided by other than the door manufacturer, and are installed at the same time as the door. This is particularly true if the door is located in the means of egress system, or is covered by accessibility requirements. As a global safety science leader, UL Solutions helps companies to demonstrate safety, enhance sustainability, strengthen security, deliver quality, manage risk and achieve regulatory compliance. This also applies to partially grouted concrete masonry walls where all ungrouted cells are filled with an approved material. UL Fire Rated Assemblies | Resources | CEMCO This guide explains the differences in product certification markings for each application. Architectural, Engineering and Construction (AEC) UL Fire Rated Search Resources, UL fire rated assemblies, designs or systems, Find UL Fire Rated Walls, Floors, Roofs, Beams and Columns, Find Walls, Floors, Roofs, Beams and Columns for Canada. (13 mm), a 1 in. Model codes may require doors installed in smoke partitions to meet the requirements for a smoke and draft control door assembly when tested in accordance with the Standard for Air Leakage Tests of Door Assemblies, UL 1784. These door frames are intended to be installed in accordance with SDI A250.11, Recommended Erection Instructions for Steel Frames, unless indicated otherwise in the individual manufacturers Classifications. Egress requirements also require these doors to be readily operable from the egress side without the use of a key or special knowledge or effort, and to include panic hardware that is listed in accordance with UL 305. Before the development of fire-rated horizontal membranes, architects used UL fire-rated wall assemblies turned horizontally or shaftwall systems for corridor ceilings. UL tests rate an entire assembly. Click the link above, each design number below represents a James Hardie 1 hour Fire Resistive Wall Assembly. 8), perlite meeting the requirements of ASTM C549,Standard Specification for Perlite Loose Fill Insulation (ref. The Mark typically describes if the frame includes sidelights and/or transom panels, may include hourly ratings, and may describe if the frame was evaluated without hose stream. 4), which measures four performance criteria, as follows: The fire resistance rating of concrete masonry is typically governed by the heat transmission criteria. For example, the IBC and ACI/TMS 216.1 include provisions for ceramic fiber joint protection for precast panels, which are similar to concrete masonry walls in that both rely on concrete for fire protection, and both are governed by the ASTM E119 heat transmission criteria (see Figure 4). When the system is activated, it is intended to monitor against unauthorized egress and allow exiting within 15 seconds, (or a maximum of 30 seconds when approved by the code authority).
