Aluminium Composite Panels: A Complete Guide for Architects & Builders
Aluminium Composite Panels: A Complete Guide for Architects & Builders
Aluminium Composite Panels (ACP) have become a staple of contemporary architecture — and for good reason. Lightweight, durable, and available in virtually any colour or finish, ACP offers designers enormous creative freedom while keeping installation costs competitive.
What Is ACP?
An ACP consists of two thin aluminium sheets bonded to a non-aluminium core. The core material determines the panel's performance characteristics:
Key Performance Parameters
| Property | PE Core | FR Core | A2 Core |
|---|---|---|---|
| Fire Rating | B2 / C | B1 / B | A2 |
| Weight (per m²) | ~5.5 kg | ~6 kg | ~7 kg |
| Max Panel Size | 1500 × 6000 mm | 1500 × 6000 mm | 1500 × 4000 mm |
| Best Use | Interiors, signage | Mid-rise facades | High-rise, public buildings |
Installation Systems
Dry-Fix Cassette System
Panels are folded into cassettes and clipped onto an aluminium sub-frame. This allows individual panels to be replaced without disturbing adjacent elements — a major advantage for maintenance.
Riveted System
A cost-effective approach where panels are fixed directly to the sub-frame with blind rivets. Suitable for flat facades with minimal panel movements.
Honeycomb-Backed Panels
For very large spans or special shapes, a honeycomb core adds rigidity while keeping weight low.
