Phonic Combo + is a composite tile with a refined white painted, monolithic, pre-finished face. It has an absorptive layer with an attenuating backer behind. Combo + not only has amazing acoustic properties (and meets Ministry of Education requirements) but also is a much better solution for seismic requirements. Performance data demonstrates an NRC of 0.85 and a minimum CAC of 42, that can be increased to a CAC of 52 quite easily.

The invention comprises two layers of material that are flexibly attached together with an air gap in between. This allows each of the layers to flex and vibrate and to define a cavity. The resulting tile weight is only 7.5kg/m².
