AC400 Ceiling System

AC400 Ceiling System

The AC400 is a bespoke expanded mesh raft ceiling system, it’s designed as a shallow standalone feature to add a dynamic, decorative ceiling to your project. Each raft can be designed bespoke to allow for integrated services, acoustic reduction and colour.

There’s the choice of steel or aluminium panels and you can pick an expanded mesh pattern from our collection and decide on a configuration that best suits your design.

AC400 Ceiling System

The AC400 can help reduce noise in busy environments with optional encapsulated black fleece acoustic infills that sit inside the ceiling rafts.

This system is ideal for hospitality environments, offices and retail spaces that need a standalone mesh raft ceiling with flexibility for service integration.

Similarly to our other systems, the standard finish for this is a powder-coated white – RAL 9010, but you can choose the perfect RAL colour to meet your client’s requirements.
