Full Name
ICC-ES AC161 – Acceptance Criteria for Foam Plastic Shapes for Parapet Applications
Scope
ICC-ES AC161 outlines the acceptance criteria for foam plastic shapes specifically designed for parapet applications in construction. The criteria focus on evaluating the suitability and performance of these shapes when used as architectural elements on parapet walls. Key aspects covered by the criteria include:
- Material properties: defining the acceptable types of foam plastic (e.g., expanded polystyrene or extruded polystyrene) and their required physical properties such as density, compressive strength, and dimensional stability.
- Attachment methods: specifying the approved methods for attaching the foam plastic shapes to the parapet wall, including the use of adhesives and mechanical fasteners, to ensure secure and durable installation.
- Weather resistance: evaluating the foam plastic shapes’ ability to withstand exposure to weather elements like rain, sunlight, and temperature fluctuations without significant degradation or loss of performance.
- Coating requirements: detailing the necessary coating systems to be applied to the exposed surfaces of the foam plastic shapes to protect them from environmental factors and enhance their longevity.
- Fire performance: assessing the fire resistance properties of the foam plastic shapes and their coating systems to ensure they meet applicable building code requirements for flame spread and smoke development.
Overall, ICC-ES AC161 serves as a guideline for evaluating the suitability and performance of foam plastic shapes for parapet applications, providing building officials, designers, and contractors with confidence in their use and ensuring compliance with safety and performance standards.
