When specifying cladding for a building facade or interior surface, architects and builders are often faced with a choice between ACP (Aluminium Composite Panels) and HPL (High Pressure Laminates). Both have distinct advantages. This guide compares them side-by-side.
What is ACP?
ACP consists of two aluminium skins bonded to a PE or mineral core. Available in metallic, solid, wood-grain and marble finishes. Lightweight — typically 4–6 kg/m². Highly suitable for exterior facades, canopies and large commercial applications.
What is HPL?
HPL (High Pressure Laminate) is made by fusing resin-impregnated kraft papers under high pressure and heat. Available in compact (self-supporting) and standard (bonded to substrate) grades. Typically 6–12mm thick, denser and more impact-resistant.
Key Differences
Weight: ACP (4–6 kg/m²) is far lighter than HPL (8–15 kg/m²), reducing structural load. Fire: HPL has natural fire resistance advantage; ACP FR grade matches with A2 classification. Finish: ACP offers metallic, mirror and 3D finishes unavailable in HPL. Cost: ACP is generally more cost-effective for large facade applications. Applications: ACP excels for exterior facades; HPL is preferred for high-impact interior surfaces like countertops and cabinets.
Verdict
For premium exterior facades, signage and commercial cladding — ACP is the preferred choice for its versatility, light weight and cost efficiency. For heavy-duty interior surfaces, school furniture and high-impact areas — HPL compact delivers superior durability. ALDURA offers both products, enabling specification of the right material for every application.
