OWAplan acoustic plaster ceiling system offers sound absorption, fire protection and a seamless monolithic design all combined in one solution.

The seamless ceiling system is part of the OWAconsult collection. It consists of our S7 suspension system, a white fleece covered mineral board and an acoustic plaster. OWAplan XS or OWAplan colour plasters partner with our OWAplan90 boards to offer class A acoustic absorption. A specialist contractor will use an airless pump to apply the plaster to create a particularly fine textured surface finish. An OWAplan acoustic plaster ceiling blends harmoniously with any architectural style. While at the same time offering pleasant room acoustics and enhanced wellbeing.

No matter if in restaurants, foyers, museums, galleries, schools, shopping arcades, hotels or in private homes, OWAplan impresses. The ‘very fine’ textured plaster finish, in white or colour, gives ceilings a pure elegance.
