Aluminum composite panels (ACPs) have revolutionized modern architecture, but not all are created equal. At the forefront of fire safety innovation stand A2 fireproof anodized aluminum composite panels—distinguished by their mineral-based white core. Unlike traditional polyethylene cores that fuel fires, these panels feature an inorganic core material (typically magnesium hydroxide) that actively resists combustion. When temperatures hit 340–490°C, the core decomposes endothermically, absorbing heat from burning surfaces and releasing water vapor to suppress flames. This mechanism enables them to achieve Europe’s highest fire rating: A2-s1-d0 certification, with near-zero smoke/droplet emissions
Why White Core Matters: Performance Advantages
1. Unmatched Fire Resistance
The white mineral core isn’t merely fire-retardant—it’s inherently non-combustible. Tests confirm it withstands 1,100°C without burning and 1,200°C without structural collapse. In full-scale facade tests like BS 8414-1, panels like ALPOLIC™ A2 demonstrated compliance with BRE 135 standards, proving their reliability in high-rise cladding systems.
2. Eco-Safety & Durability
Zero toxins: Halogen/VOC-free, producing no corrosive smoke during fire exposure.
Weather resistance: Anodized aluminum surfaces coupled with FEVE fluorocarbon coatings (e.g., LUMIFLON™) offer UV stability and color retention for 20+ years.
Structural integrity: The I-beam effect between aluminum skins and rigid core ensures high stiffness at minimal weight (4mm panel: ~7.1 kg/m²).
3. Design Versatility & Ease
Custom fabrication: Cuts, bends, and rolls like metal, enabling curved facades and complex geometries.
Aesthetic range: Anodized finishes include metallic, woodgrain, stone, and 3D textures—all over a standardized white core that prevents dark edge lines after cutting.

Real-World Applications
From Zurich Airport’s facade to Hangzhou Fortune Center’s twisting towers, white-core A2 panels merge safety with aesthetics. They dominate high-risk venues like subways and hospitals where regulations mandate non-combustible materials. Increasingly, architects also specify them for:
Interior feature walls: Leveraging the core’s sound insulation (26 dB for 4mm panels).
Renovations: Lightweight nature eases retrofitting on aging structures.
