Types of ACM Based on Fire Resistance:

PE Core (Polyethylene core)

NOT fire-resistant

Highly flammable; banned in some countries for use on high-rise buildings

Used in signage and interiors, not recommended for building facades

FR Core (Fire-Resistant core)

Contains mineral fillers (like magnesium hydroxide) mixed with polyethylene

Improved fire performance, meets many fire codes for facades

Used in low- to mid-rise buildings

A2 Core (Non-combustible core)

Mostly inorganic minerals, very low organic content

Achieves EN 13501-1 A2 fire rating (European standard), which is near non-combustible

Highest level of fire safety for ACM, suitable for high-rise buildings
