ICC-ES AC81

Full Name

ICC-ES AC81 – Acceptance Criteria for Natural Fiber Insulation

Scope

ICC-ES AC81 outlines the requirements for evaluating natural fiber insulation materials used in building construction. The scope includes:
  • Material properties: it specifies the acceptable types of natural fibers, such as cotton, cellulose, or wool, and their required properties for thermal resistance, moisture resistance, and fire performance.
  • Testing procedures: it details the standardized testing methods for evaluating the thermal performance, moisture resistance, and fire resistance of natural fiber insulation.
  • Installation requirements: it provides guidelines for the proper installation of natural fiber insulation to ensure its effectiveness in providing thermal insulation and preventing moisture problems.
  • Evaluation and certification: it outlines the process for evaluating and certifying natural fiber insulation products to ensure they meet the acceptance criteria.
ICC-ES AC81 is important for manufacturers to demonstrate that their natural fiber insulation products meet the necessary performance and safety standards. It also provides valuable information to builders, designers, and homeowners for selecting and installing appropriate insulation materials for energy efficiency and sustainability.
