Acrylic vs ACP Sign Boards: Differences, Pros, and Best Choice

Acrylic and ACP serve different functions in sign construction. Acrylic is commonly used for letters, faces, and diffuser panels, while ACP is commonly used for fascia cladding and opaque backgrounds.

What is an ACP Sign Board? Aluminium Composite Panel (ACP) consists of a core between thin aluminium sheets. - **The Role:** ACP is commonly used as an opaque fascia or backdrop panel that can cover uneven surfaces and conceal selected wiring or supporting elements. - **Advantages:** It is available in multiple colours and finishes and can be routed for stencil-cut details. - **Cons:** It is opaque. You cannot pass light through the solid ACP panel itself.

What is an Acrylic Sign Board? Acrylic is a transparent or coloured polymer sheet available in different thicknesses and finishes. - **The Role:** Acrylic is used to fabricate the **individual glowing 3D letters** and diffuser panels. It is cut precisely by lasers, heated, and bent to form glowing 3D shapes. - **Advantages:** Selected acrylic types can transmit and diffuse light and can be cut into detailed letter or logo shapes. - **Cons:** Acrylic can be more vulnerable to impact than metal, and suitability depends on thickness, fixing, and exposure.

Combining ACP and acrylic For many retail shops and clinics, an **ACP backdrop with mounted 3D acrylic LED letters** is a practical option when the site needs a flat facade finish and illuminated lettering. This combines an opaque ACP backing surface with acrylic letters that can be illuminated for night-time visibility.
