EchoPanel® Longitude

Have a Question?

Reminiscent of wood panelling, EchoPanel® Longitude is characterised by refined v-groove cuts that bring an understated three-dimensional element to these acoustic wall panels.

Panels can be joined seamlessly thanks to Longitudes bevel cut edge, and are available in the full suite of EchoPanel® 12mm colours, making them easy to incorporate in most interior fit-out schemes. For higher acoustic performance, EchoPanel® Longitude is also available in EchoPanel® 24mm.
