Noise protection barriers

The issues of traffic noise on railways, roads and motorways have been recently more and more discussed. That is why our company deals with the production of special panels for the construction of acoustic walls. The panel is composed of a reinforced-concrete precast component, a layer of sound absorbing material and rubber boards. Walls are characterized by long lifetime and by their ability to keep their properties over a long time even under adverse weather conditions.

Noise barriers manufactured by Intertech Plus s.r.o. are designed to absorb or
divert noise generated mainly by tram vehicles along tram lines. The effectiveness of the noise barrier is from 5 dB- 10dB.

CATEGORY A3 ABSORPTION PANELS

Material

  • The absorber made of recycled rubber granulate is glued to a load-bearing sandwich panel with a polyurethane adhesive
