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
