ACRYLITE® Soundstop XT with Bird Guard
Transparent Noise Barriers
Product
This is a highly transparent specialty grade of acrylic that helps to prevent bird collisions.
Properties
In addition to the well-known and proven properties of standard ACRYLITE® sheet, such as:
- Excellent light transmission and brilliance
- Superior weather resistance
- Ease of fabrication
- High surface hardness
- Lightweight – half the weight of glass
- 11 times the impact strength of glass
Special Features
- Many traditional sound barriers create a tunnel effect when driving, but the transparency of ACRYLITE® Soundstop XT with Bird Guard allows for more comfortable driving conditions.
- It offers a superior sound reduction rating (STC) of 32 dB or higher by ASTM E90.
- Large noise barrier panels reduce the need for excess supporting structures and thus enhance the transparency of the barrier.
- It is available in colorless sheet as well as various transparent colors.
- Embedded black stripes reduce the likelihood of bird collisions.
Applications
These properties make ACRYLITE® Soundstop XT with Bird Guard especially suitable for:
- Noise control along roads and railways
- Wind barriers on bridges
- Impact resistant glazing for pedestrian bridges/greenways
Machining
- It can be machined just like standard ACRYLITE® sheet.
Physical forms
This material is available in the following sizes, thicknesses, and stripe directions:
Length: up to 20ft (6.1m)
Width: up to 6.5ft (2.0m)
Thicknesses: 15, 20, 25 mm
Stripe direction:
- (-XLA) along length
