Key Features of UL V497
UL V497 provides a 1-hour fire rating for partitions and walls, requiring steel stud framing, gypsum board, and fire-shield materials to ensure fire resistance and structural integrity.
1-Hour Fire Rating for Partitions and Walls
UL V497 ensures partitions and walls meet a 1-hour fire rating, providing a critical barrier against fire spread. This rating is achieved using minimum 2 1/2″ steel studs and 5/8″ Fire-Shield materials. The assembly must include gypsum board on both sides, with specific construction details to maintain fire resistance. Compliance with UL standards ensures safety and structural integrity during fires, making it suitable for both commercial and residential applications. Proper installation of these components is essential to uphold the fire rating and protect occupants and property effectively.
Construction Requirements for Steel Stud Framing
UL V497 specifies that steel stud framing must meet strict construction requirements to ensure fire resistance. The minimum width for steel studs is 3-5/8 inches, and they must be paired with 5/8-inch Fire-Shield materials. Proper alignment and installation of these components are critical to maintaining the integrity of the fire-rated assembly. Additionally, all construction details, such as those outlined in SS 111, must be followed precisely to comply with UL standards. These requirements ensure that the assembly can withstand fire conditions for the specified 1-hour rating, providing reliable protection for occupants and property.
Role of Gypsum Board in Fire-Resistant Assemblies
Gypsum board plays a crucial role in UL V497 fire-resistant assemblies by providing a barrier against heat and flames. It is typically installed on both sides of steel stud framing to ensure maximum protection. The board’s density and composition help slow the spread of fire, while its durability maintains structural integrity during exposure. For a 1-hour fire rating, the assembly often requires multiple layers of gypsum board, with specific thicknesses and types, such as Type X, to meet UL standards. Proper installation, including tight joints and secure fastening, is essential to achieve the desired fire-resistance rating, making gypsum board a fundamental component in these systems.
Design and Application
UL V497 designs involve precise construction details, including steel stud framing and gypsum board installation, to ensure fire resistance and meet safety standards in various building applications.
Head of Wall Details and Fire-Resistant Materials
Head of wall details in UL V497 designs require precise construction to maintain fire resistance. Steel studs with minimum dimensions of 2 1/2″ are essential, paired with 5/8″ Fire-Shield materials. Gypsum boards must be installed on both sides, ensuring a seamless seal. These details prevent fire spread at wall-to-ceiling or wall-to-floor connections. Fire-resistant materials like gypsum and fire-shields are critical for maintaining integrity. Proper installation ensures compliance with UL standards, providing a 1-hour fire rating. These specifications are detailed in the UL V497 PDF, which includes CAD files for accurate implementation. Adherence to these details is vital for safety and code compliance in fire-resistant construction.
Steel Stud Dimensions and Fire-Shield Requirements
Steel stud dimensions in UL V497 designs require a minimum width of 3-5/8 inches to ensure structural integrity and fire resistance. Fire-shield materials must be at least 5/8 inches thick, providing critical protection against fire penetration. These specifications, outlined in the UL V497 PDF, ensure compliance with fire safety standards. The CAD files and construction guidelines detail precise installation methods for steel studs and fire-shields. Proper adherence to these requirements is essential for maintaining the 1-hour fire rating and ensuring the safety of occupants in commercial and residential buildings. These details are non-negotiable for architects and builders aiming to meet regulatory demands and safeguard against fire hazards effectively.
Acoustical Performance and Sound Transmission
UL V497 assemblies are designed to provide effective sound transmission control, enhancing acoustical performance in partition walls. The combination of steel studs and gypsum boards minimizes noise transfer, ensuring quieter environments. Detailed in the UL V497 PDF, specific constructions achieve STC ratings suitable for commercial spaces. Acoustical test reports, available as PDFs, validate these performance metrics. Builders can utilize Revit models to integrate these designs seamlessly. Compliance with sound transmission requirements is crucial for meeting building codes and occupant comfort. The design ensures both fire safety and acoustical efficiency, making it a comprehensive solution for modern construction needs. Proper material selection and installation are key to achieving optimal results.
Related UL Designs and Comparisons
UL V497 is compared to designs V438, V488, and V449, offering similar fire ratings but differing in load-bearing capabilities and specific assembly requirements, as detailed in the PDF.
UL Designs V438, V488, and V449: Similarities and Differences
UL Designs V438, V488, and V449 share similarities with V497 in providing fire-rated assemblies, but they differ in specific applications and ratings. V438 and V488 are commonly used for load-bearing and shaftwall assemblies, offering 1- to 4-hour fire ratings, while V449 focuses on non-load-bearing partitions. Unlike V497, which is specifically designed for 1-hour fire-rated partitions, these designs cater to varying structural demands; All designs emphasize the use of certified materials and construction methods to meet fire-resistance standards.
