We are sound absorption specialists with metal acoustic ceilings and ceiling tiles.


An Australian owned company, Renhurst Ceiling Systems has been servicing the building industry for over 50 years, focusing solely on ceiling systems.

The Renhurst range includes the Melbourne designed and made RippleTone and RippleSound metal acoustic ceilings. These exciting products can form full ceilings, infills, ‘floating’ or feature panels.

The Renhurst Ceiling Tile range includes Mineral Fibre Acoustic Tiles from Daiken (Japan), USG Boral and BMBN (China) as well as Plasterboard and Metal Ceiling Tiles.

We encourage you to tap into our wealth of industry knowledge and experience for your next project – we are very happy to help.

RippleTone Acoustic Metal Ceilings provide designers and architects with the freedom to create exciting and unique effects, all the while delivering excellent noise reduction capabilities with a proven high acoustic rating.


RippleSound combines corrugated, perforated aluminium sheet with an acoustic / thermal polyester insulation to trap and break down sounds, as well as control moisture within Aquatic Centre environments.


RenAcoustic Ceiling Tiles are manufactured from high quality compressed fibreglass, achieving a excellent 0.90 NRC rating. Lightweight and simple to install, they are pleasing to the eye as well as the ear.


Acoustic Control in Brief

Noise Absorption

Noise absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy.

When sound in a room collides with the walls, part of the sound’s energy is reflected and part is absorbed into the walls. Soundproofing aims to absorb as much sound energy as possible.

In general, soft, porous materials serve as good acoustic insulators, whereas hard, impenetrable materials reflect most.

Noise Control

Airborne sound or noise travels through walls or floor and ceiling assemblies and can emanate from either human activities in adjacent living spaces or from mechanical noise within the building.

Fabric covered panels are an excellent way to maximise the acoustical absorption. Fabric can be wrapped around substrates to create what is referred to as a “pre-fabricated panel”. Such fabrics are generally acoustically ‘transparent, meaning that they do not impede a sound wave.

NRC Rating

The Noise Reduction Coefficient (commonly abbreviated NRC) is a scalar representation of the amount of sound energy absorbed upon striking a particular surface.

An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption.

RH Moisture Rating

Relative humidity (abbreviated RH) is the ratio of the partial pressure of water vapour to the equilibrium vapour pressure of water at the same temperature.

Relative humidity depends on temperature and the pressure of the system of interest.

CASE STUDY: Ballarat Aquatic Centre

As the saying goes “when you’re onto a good thing stick to it”. This is certainly the case at the recently completed extension to the Ballarat Aquatic Centre.

RippleSound was installed in the original building 21 years ago. Based on the excellent performance of the original ceiling, the choice of ceiling for the new building extension was easy.

A mechanically fixed vapour barrier system is a feature of the RippleSound system providing superior moisture control and ensuring a product lifespan that is the envy of our industry.

RippleSound was installed in 29 metre lengths, alleviating the need for any unsightly joins and allowing installation to be completed well ahead of schedule.
