ICC-ES AC181
Full Name
ICC-ES AC181 – Acceptance Criteria for Rigid Cellular Polyurethane Panels Used as Exterior and Interior Wall Cladding
Scope
ICC-ES AC181 establishes the guidelines for evaluating rigid cellular polyurethane foam panels intended for use as both exterior and interior wall cladding.
The scope of AC181 includes:
- Types of panels: it covers rigid cellular polyurethane foam panels, which are lightweight and insulating materials commonly used in construction.
- Application methods: it addresses both mechanical attachment (e.g., screws, nails) and adhesive attachment methods for securing the panels to the wall structure.
- Performance requirements: it outlines the performance requirements for the panels, including structural integrity, fire resistance, thermal insulation, moisture resistance, and durability.
- Test methods: it specifies the test methods for evaluating the panel properties under various conditions, such as wind loads, impact resistance, fire exposure, and moisture exposure.
- Evaluation criteria: it provides criteria for assessing the test results and determining the suitability of the panels for use as exterior and interior wall cladding in compliance with building codes and standards.
Overall, ICC-ES AC181 serves as a comprehensive guideline for evaluating the performance and suitability of rigid cellular polyurethane panels for wall cladding applications, ensuring their safety, effectiveness, and compliance with building regulations.
