ICC-ES AC187
Full Name
ICC-ES AC187 – Acceptance Criteria for Polyester Loose-fill and Blanket Insulations
Scope
ICC-ES AC187 defines the acceptance criteria for evaluating polyester loose-fill and blanket insulations used in building construction. The criteria focus on ensuring the insulation’s performance and suitability for various applications within the building envelope.
Key areas covered by the criteria include:
- Material composition: specifying the acceptable types of polyester fibers and their required properties for thermal performance, moisture resistance, and fire safety.
- Thermal performance: establishing minimum R-values (thermal resistance) for different insulation thicknesses and applications, ensuring compliance with energy code requirements.
- Physical properties: defining requirements for density, compressive strength, and dimensional stability to ensure the insulation maintains its form and effectiveness over time.
- Fire performance: assessing the insulation’s fire resistance properties, including flame spread, smoke development, and smoldering resistance, to ensure compliance with building codes and safety standards.
- Installation guidelines: providing recommendations for proper installation of loose-fill and blanket insulations to achieve optimal thermal performance and prevent settling or gaps.
By adhering to AC187, manufacturers can demonstrate that their polyester insulation products meet the necessary performance and safety standards, giving building officials, designers, and contractors confidence in their use for thermal insulation in various building components.
