Tech Talk: Premier SIPS Updated ESR & New ESL - Expanding Design Flexibility

Key Updates to Premier SIPS ICC ESR-4524

1. Updated Code Evaluations:

• Now evaluated for compliance with the latest ICC Codes: 2024, 2021, and 2018.
• Includes evaluation against the 2022 California Building Code (CBC) and the 2023 Amended 2022 Los Angeles Building Code (LABC), ensuring adherence to the newest standards.

2. Expanded OSB SIP Facing Options:

• Allows for OSB facing thicknesses ranging from 7/16” to ¾”.
• This flexibility can help meet a variety of design requirements, such as:
  • Thermal barrier qualification.
  • Enhanced impact strength for floors.
  • Greater nail or screw capacity for wall and roof cladding attachments to handle wind uplift and durability requirements.
  

3. Increased Aspect Ratio Options:

• Aspect ratios of 1:1, 2:1, and 3.5:1 are now included for wall designs in Seismic Design Table 11.
• These ratios apply to all wall heights listed in Axial Load Tables 5 and 6, providing designers with more options to meet specific seismic and structural requirements.

4. Enhanced Diaphragm Design Flexibility:

• Table 12 Diaphragm Designs now offers engineers more flexibility in determining the location and spacing of boundary supports, ensuring designs are optimized for each unique project.
  

5. Integrated Fire Resistance Features:

• Our 1-hour ASTM E 119 Fire Resistant Designs for Ceiling/Floor Assembly (Section 4.2.11.1) and Wall Assembly (Section 4.2.11.3) now include the use of nail attachment for Box/Block Splines.
• This means these assemblies can address fire, diaphragm, and seismic resistance simultaneously, providing enhanced safety and performance.

• Premier SIPS are now recognized for compliance with the International Wildland-Urban Interface Code.
• When built using ASTM E 119 and ASTM E 108/UL 790 assembly methods, Premier SIPS can be used in residential and commercial structures within Wildland-Urban Interface Zones across the US.

New ICC ESL: Expanding Multi-Story Application*

Premier SIPS for Multi-Story Structures:

• Many designers turn to Premier SIPS for multi-family dwellings, hotels, and dormitories. With this in mind, we’ve taken steps to address fire safety for multi-story applications.
• A successful NFPA 285 “Base Wall” Test was conducted, proving that with a 5/8” layer of exterior Type X gypsum board, Premier SIPS prevent the propagation of vertical fire on a multi-story structure's exterior.
• This NFPA 285 Base Wall can be paired with a variety of fire-safe cladding options, including cement board, metal, cultured stone, brick, EIFS, and more, providing additional flexibility for designers.
