Acoustic ceiling solutions manufacturer OWA UK has extended its product range with the development of the new System S 80 demountable metal ceiling raft – a stylish interior solution for disguising M&E installations and providing improved sound absorption.

The new System S 80 ceiling raft is a bespoke solution, made to order and available in a wide range of sizes, shapes and colours. The full metal suspended ceiling system can be specified in a choice of material finishes, including mesh, perforated or ‘elapto’ mesh, and can be modified to achieve the required acoustic performance. Through the use of an acoustic pad, OWA UK’s S 80 metal ceiling raft can achieve class A sound absorption, however, the combination of a perforated pattern and black acoustic fleece will achieve class C as standard.

OWA UK’s new demountable ceiling raft has been designed to help cover unsightly M&E installations and the panels can be easily removed for access, maintenance and cleaning. The low profile, hidden hanging system is ideally suited for open soffit interior design schemes and thanks to its full metal construction, offers exceptional durability.

As part of OWA UK’s bespoke offering which gives specifiers even greater design flexibility, the height of the system can be tailored to suite different interior styles. This can include a low profile for a minimalistic appearance, or the system being made taller with a pronounced visible edge for bolder design schemes.

The new System S 80 demountable ceiling raft can be specified in OWA UK’s new ‘RAW metal’ surface coating which offers an attractive and textured rust-brown aesthetic or can be supplied in any RAL colour. As the system requires fewer soffit fixings than comparable traditional fleece or fabric acoustic absorbers, it is easy to assemble and install using M6 threader rods, and is available as a kit of machined parts or standard length profiles.

System S 80 has already been specified on a number of high profile projects including the recently completed B and C buildings at the new Assembly Bristol mixed use scheme which has been constructed by Galliford Try with AHMM Architects. The system also features on The University of Birmingham’s Molecular Science building, with OWA UK working alongside Morgan Sindall and Associated Architects.
