Acoustic Screens and Barriers - Profiled Acoustic Screen
ASB2-1 - Profiled Acoustic Screen around grid transformer for environmental noise control
Acousticabs Profiled Screens are designed for use where a large acoustic barrier is required on a permanent basis around fixed external noise sources. The profiled acoustic system is suitable for all types of major environmental noise control. Typical applications are noise control barriers around electrical substations, air handling equipment and delivery areas for supermarkets and factories. Screens are a composite construction built around a core of noise absorbing acoustic slab loaded with high density Acousticurtain. The level of acoustic performance is tailored to suit the application by altering the core make up. The outer surface of the screen is faced with profiled steel. The inner surface is faced with APP profiled acoustic liners. The acoustic core is protected with a water repellent membrane. Depending on size and environmental conditions, screens may be supported on a concealed internal RHS frame or on exposed hot rolled structural steelwork.
Indicative acoustic performance is shown below. In practice the level of performance achieved is influenced by the position and size of the screen in relation to the sound source and to the measurement point

The profiled acoustic screen system is designed for large applications. The profiled outer sheets are manufactured to any reqired length.
Most colours from the pre-coated steel range are available
(see 'Pre-coated Colour Range')
Support steelwork is galvanised or powder-coated. The exterior sheets are manufacture from pre-coated steel.
