Impact Acoustic Circular Ceiling Panel

Impact Acoustic Circular Ceiling Panel

The classic circular shape of Impact Acoustic’s round acoustic ceiling panels are an easy shape to work with. They create an exciting pattern and are a great acoustic solution for all types of spaces. The panel has an elegant V-cut on the underside adding to the design statement. The panel is also available bespoke diameters and without the v-cut.

The acoustic panels are suspended horizontally from the structure above, either fixed to a frame and secured by safety hooks or with suspension cables screwed directly into the panel.
