AC107 - Sandwich Panels

Overview

Sandwich panels are layered building panels consisting of two stiff, thin face skins bonded to a lightweight thick core. The core is often an insulating foam or other low-density material, and the face sheets can be metal, wood, or composite. This construction produces a component that is very strong and rigid for its weight, making it useful for walls, roofs, or floors that need both structural support and thermal insulation. Sandwich panels are commonly used in commercial and industrial construction where speed of installation and energy efficiency are important.

Purpose

This acceptance criteria provides a basis for evaluating sandwich panel systems that may not be directly covered by existing codes. It establishes testing protocols, structural performance requirements, and quality standards needed for code approval of these composite building elements.

Benefits of Compliance

• Nationwide acceptance by building officials for sandwich panel installations
• Streamlined approval process for composite panel systems
• Third-party verification of structural and thermal performance
• Enhanced marketability for innovative building systems
