ICC-ES AC269.2 – Acceptance Criteria for Proprietary Sheathing Jobsite-attached to Wood Light-frame Wall Construction Used as Shear Walls
Scope
ICC-ES AC269.2 focuses on the acceptance criteria for proprietary sheathing products that are attached to wood light-frame wall construction at the job site and used as shear walls. It is similar to ICC-ES AC269.1 but with an emphasis on jobsite attachment methods.
The scope includes:
- Material specifications: evaluating the properties of the proprietary sheathing material, including its strength, stiffness, and durability in relation to jobsite conditions.
- Jobsite attachment methods: assessing the effectiveness of the specific attachment methods used at the jobsite to secure the sheathing to the wood light-frame wall.
- Structural performance as shear walls: evaluating the ability of the assembled wall system to resist lateral loads and provide adequate shear resistance, specifically considering the impact of jobsite installation variations.
- Compliance with IRC requirements: ensuring that the sheathing, attachment methods, and the resulting shear wall assembly meet the relevant requirements of the International Residential Code (IRC).
By establishing these acceptance criteria, ICC-ES AC269.2 aims to ensure the safe and effective use of proprietary sheathing products as shear walls in wood light-frame construction, even when installed under varying jobsite conditions. It provides a standardized framework for manufacturers, designers, and building officials to assess the suitability of these products for use in residential construction with a focus on real-world installation scenarios.
