ICC-ES AC377 – Acceptance Criteria for Spray-applied Foam Plastic Insulation

Scope

ICC-ES AC377 outlines the acceptance criteria for spray-applied foam plastic insulation used in building construction. It covers various aspects of product performance, including:
  • Thermal resistance: evaluates the insulation’s ability to resist heat flow.
  • Fire performance: assesses the insulation’s resistance to fire and its contribution to fire spread.
  • Durability: determines the insulation’s ability to withstand environmental factors like moisture, temperature changes, and aging.
  • Structural performance: evaluates the insulation’s ability to maintain its shape and integrity under load.
  • Application: provides guidelines for the proper installation and use of spray-applied foam plastic insulation.
The purpose of AC377 is to provide a standardized framework for evaluating these products, ensuring they meet the minimum requirements for safety and performance in building construction.
