ACRYLITE® Soundstop NT Technical Information
Product
ACRYLITE® Soundstop NT CC is a highly filled, non-transparent grade of cast acrylic.
Properties
In addition to the well-known and proven properties of ACRYLITE®, such as:
- Extremely high weather resistance
- Ease of fabrication
- High surface hardness
- Low weight
- 100% recyclability
ACRYLITE® Soundstop NT offers the following special features:
- Large noise barrier elements reduce the need for steel supporting structures
- Achieves the highest airborne sound reduction category (B3) of EN 1793-2, and also meets all requirements of EN 1794-1,2
- Available in various colors
- Can be supplied with a matte or gloss surface
- Since the sheets are homogeneously colored, there is no flaking
Applications
These properties make it especially suitable for:
- Noise control along roads and railways
- Wind barriers on bridges
Machining
- It can be machined just like standard ACRYLITE®
- Lightweight applications for noise barriers
Physical forms
It is available in the following size:
Standard size:4000 x 2000 mm
Thickness:12 mm
Other surfaces, sizes, and thicknesses are available on request
Also available as NT CC with embedded polyamide threads
