Full Name
ICC-ES AC295 – Acceptance Criteria for Laminated Fibrous Board Sheathing Material
Scope
ICC-ES AC295 establishes the acceptance criteria for laminated fibrous board sheathing material used as both structural and nonstructural sheathing on wood and steel stud shear walls in Type V construction buildings.
The scope of AC295 includes:
- Material properties: defines the required physical and mechanical properties of the laminated fibrous board sheathing, such as bending strength, stiffness, water resistance, and vapor permeability.
- Shear wall performance: outlines the criteria for evaluating the racking resistance of shear walls constructed with the sheathing material, considering factors like fastener type and spacing, stud size, and wall height.
- Fire resistance: addresses the fire performance of the sheathing material and its contribution to the fire resistance rating of the wall assembly.
- Durability and weather resistance: evaluates the sheathing material’s ability to withstand environmental exposure, including moisture, temperature variations, and ultraviolet radiation.
By establishing these acceptance criteria, ICC-ES AC295 aims to ensure that laminated fibrous board sheathing meets the necessary safety and performance standards for use in building construction. It provides a standardized framework for manufacturers, designers, and building officials to assess the suitability of this material for various applications.
