ICC-ES AC356
Full Name
ICC-ES AC356 – Acceptance Criteria for Moisture Drainage Systems Used with Exterior Cement Plaster or Adhered Masonry Veneer Walls
Scope
ICC-ES AC356 outlines the acceptance criteria for evaluating moisture drainage systems used with exterior cement plaster or adhered masonry veneer walls. These systems are designed to manage moisture behind the wall cladding, preventing damage and promoting durability.
The scope of AC356 includes:
- Materials: specifies the requirements for the materials used in the moisture drainage system, ensuring they are durable, resistant to corrosion, and compatible with the wall assembly.
- Design and performance: criteria for evaluating the design and performance of the system, including its ability to drain water, resist wind pressure, and maintain proper airflow.
- Testing: standardized test methods for assessing the drainage capacity, air permeability, and wind load resistance of the system under various conditions.
- Installation: guidelines for the proper installation of the moisture drainage system, including attachment methods, flashing details, and integration with other building components.
By adhering to AC356, manufacturers can ensure that their moisture drainage systems meet the necessary standards for performance and reliability in protecting exterior wall systems from moisture damage.
