S80 acoustic raft

OWAtecta S80 acoustic raft is a metal, demountable, free-hanging, ceiling absorber. Furthermore, it’s a stylish, modern interior solution for disguising M&E installations and providing improved sound absorption.

Firstly, what is an acoustic ceiling raft? At OWA, we define a raft as an individual, horizontal ceiling product featuring a suspension system secured to the soffit incorporating multiple removable or fixed panels.

The S80 acoustic raft is a bespoke solution, made to order and available in a wide range of sizes, shapes and colours. The suspended ceiling raft can be specified in a choice of metal surfaces; mesh, perforated or ‘elapto’ mesh. Through the inclusion of an acoustic pad, S80 acoustic rafts can achieve class A sound absorption. However, the combination of a perforation and black acoustic fleece will achieve class C as standard.

The S80 acoustic raft helps to cover unsightly M&E installations. Therefore, the panels are removable for access, maintenance and cleaning. The low profile, hidden hanging system is ideally suited for open soffit interior design schemes. Also, thanks to its full metal construction, S80 offers exceptional durability.

  • Bespoke heights available; minimalist low profile or a taller pronounced edge
  • Any RAL colour or our new ‘RAW metal’ finish
  • Easy to assemble and install with M6 threaded rods
