OWAcoustic premium Sandila/O is a textured, plain, white painted, sand covered ceiling tile. It’s a plain tile and is available with a square edge and 24 mm tegular edge. We machine the tegular edges and paint the surface and edges to match.

Sandila/O is a quality, cost-effective, plain utility tile, suitable for general use. We recommend it for areas where noise levels from activities is low so a high sound absorption is not necessary.

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.

Sandila/O 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.
