Full Name
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.
