What is an Aluminum Composite Material (ACM) Panel?
ACM panels provide building owners and developers with a stylish and practical product that can be utilized for renovation and new construction projects.
Composition and Structure of ACM Panels
Aluminum composite material panels include two thin, pre-painted flat aluminum composite panels bound to a non-aluminum core center. Manufacturers combine natural fibers extracted from plants and animals with aluminum foil to produce an aluminum composite, which creates a more effective, robust, flexible, and aluminum composite than those made with synthetic fibers. Manufacturing the composite panel system involves a continuous lamination process of compacting the core between two aluminum sheets, then flattening the product and applying a protective coating.
Different Types of Core Materials Used in ACM Panels
Manufacturers typically offer two types of core materials for ACM panels: Polyethylene (PE) and Fire-Retardant (FR) cores.
PE cores provide a lightweight and cost-effective option, suitable for low-rise buildings up to two stories. They are ideal for projects that require flexibility and ease of installation without high fire safety demands.
Fire-retardant cores, while more expensive, are designed to meet strict fire safety regulations for multi-story buildings. These cores offer improved fire resistance and are preferred in commercial and high-occupancy construction projects.

Fire Resistance and Safety Features
Modern ACP systems are engineered to meet strict fire safety standards. Under the 2021 International Building Code (IBC), wall assemblies using ACM panels must pass key tests such as NFPA 285, ASTM E84, and NFPA 268.
Fire-retardant cores—typically 3mm, 4mm, or 6mm thick—use materials like alumina trihydrate (ATH) or magnesium hydroxide (MDH) combined with a polymer base to enhance fire performance. Compliance with NFPA 285 ensures better protection during fire events, reducing risks to both buildings and occupants.
Low-Maintenance Requirements
ACP wall systems maintain their appearance and performance over time with minimal maintenance. Their durable, coated surface resists weathering, UV exposure, corrosion, and termite damage, maintaining flatness and color consistency for years while reducing long-term maintenance costs.
Thermal and Acoustic Insulation Properties
ACP panels naturally reflect heat and light, reducing energy consumption and improving building efficiency. When finished with cool coatings, they further enhance reflectivity and lower surface temperature. Additionally, their layered composition helps absorb vibrations and sound, effectively reducing noise transmission and improving indoor acoustic comfort.
Applications of ACP Wall Systems
Eye-catching, durable, and lightweight, ACP wall systems are a practical solution for enhancing both exterior and interior spaces of residential, commercial, and institutional buildings.
Exterior Cladding and Façade Systems
For new construction and remodeling projects, ACM panel exterior claddings and façades offer architects and builders a system that improves a building’s integrity, appearance, and sustainability. Long-lasting ACM exterior cladding resists rain, wind, UV light, flying debris, and other environmental stresses.
