OWAcoustic premium Constellation is a 15 mm thick, white painted, ceiling tile with a celestial pattern. It has needling which offers class C sound absorption and is available with a square edge.

Constellation is a quality, cost-effective, class C solution, suitable for communal spaces and back areas. In particular, we recommend it for retail, education and industry. It helps to lower reverberation times in moderately noisy spaces.

OWA manufactures our mineral wool tiles from naturally occurring and recycled materials via a wet-felt process. We have virtually zero VOCs and no formaldehyde resin in the formulation of our boards.

Constellation tiles form a complete suspended ceiling system when combined with our exposed tee grid and perimeter trim. They are easy to install and demount for service access. OWA mineral board is dense and firm, therefore the tiles will retain integrity when handled frequently. Over time, dirt and dust does not accumulate on the surface, whereas for lower density products, dark patches may appear. The tiles are easy to trim onsite with a utility knife. Cut edges will not crumble and do not need any further treatment.
