Acrylic sound barrier

In current time, the increased volume of traffic noise has become a major environmental problem. So noise control along the traffic routes is increasingly gaining in importance to control noise levels in the facing of rising traffic volume.And this is promoting the increased use of sound barrier solutions in the design of modern road and rail infrastructure.

Our acrylic noise barrier is a transparent cast acrylic sheet designed to prevent traffic noise reducing stress for residents and increasing the amount of light in the urban environment. Acrylic sound barrier sheet is the high strength cast acrylic sheet with embedded reinforced threads.These threads restrain any fragments caused due to breakage during an accident, and prevent  from falling onto the road .

The SUNDECOR acoustic sound barrier sheet approved throughout the world for use on bridges without additional restraint system.

Features：

  • Reducing the voice to 34DB.
  • Preventing the bird from hinting the sheets.
  • High impact strength, the thread inside can avoid the second hurt.
  • Perfect transparency and the light transmittance with 93%.
  • Excellent electrical insulation, very light in weight.
  • Strong surface hardness and good weather resisting property.
  • Beautiful in colour, easy to clean.

Application：

Sound barrier acrylic sheets displays fantastic resistance to noise, Especially noise from vehicles,  so noise barriers are regularly specified in for large government transport infrastructure projects. Such as:

  • Overpasses
  • Highways
  • Birds Protection
  • Bridges
  • Railways
  • Overpasses
  • Living area
  • Other Projects needs sound proof material

Why is the acrylic stiffener sheet used for acoustic barriers?

  • Acrylic board also known as plexiglass is an important thermoplastic material early developed. Mainly used in construction, sanitary ware, advertising, decoration and so on. As a sound barrier transparent material, there are less applications in domestic. This board has good weather resistance, no need for UV treatment, color transparent, large surface which can be made and simple fixed way and so on. While it is conducive to clean dust, with good landscape effect.
  • Sound insulation of this acrylic sheet can achieve 30db(A). It can fully meet the requirements of the sound barrier, and has high transmittance, resistance to yellowing, and a good landscape effect. But the problem is: thicker plate prices are more expensive and impact resistance worse than the pc board. Sound barrier sheets are used in many domestic projects, with height 3.65m, can reduce 6-7db. At present, mass production of transparent acrylic sheet of 12-20mm thick has been realized in China. By means of reinforcement in the plate, the impact resistance is also improved. There are more and more countries use acrylic stiffener to build sound barrier.
