The exponential growth in highway and bridge infrastructure projects across the Australian continent has resulted in tremendous demand for noise abatement solutions.
In today’s urban environment noise abatement and mitigation are indispensable requirements for motorways, tunnels and bridges in close proximity of residential and commercial precincts. Traditional timber and concrete noise barriers often have unfavorable visual impact, both for residents and road users, who may experience a “tunnel” effect.
In Australia various road and transport authorities have proposed the use of clear or tinted colour transparent noise barriers for key projects.
Shatter resistant options are available by the embedding of a filament within the noise barrier with the additional benefit of preventing bird strikes.
DONCHAMP® NoiseGuard cast acrylic is a specially designed & developed acrylic grade, which is highly weather resistant (30-year Clear limited manufacturer’s warranty), excellent clarity & optical properties, exceptional mechanical properties & rigidity, simple to fabricate (cut, bend & polish), whilst reducing the environmental noise pollution levels & hazardous high winds from roads, highways, bridges & rails.

The combination of both the functional and visual attractions, makes DONCHAMP® NoiseGuard panels an excellent choice for acoustic / wind barrier applications on highways, bridges and railways. The transparency of the panels opens the landscape for the road/rail user, whilst offering sound control and protection to the public (both residents and road users). DONCHAMP® NoiseGuard also can be easily transported, having approx. 11 times the break resistance of glass & considerably lower weight. Any light surface marks on DONCHAMP® NoiseGuard can be polished & marks removed.
DONCHAMP® NoiseGuard through its unique manufacturing process has one of the highest transparent substrate surface hardness, enabling ease of use in numerous commercial applications.
