HABITAT / Metal Noise Barriers


Difracta steel panels. The panel consists of sawtooth-shaped sheeting, and is specially conformed so that the sound-absorbing element (polyester or mineral wool) can be positioned horizontally, shielded from adverse  weather.It has been specifically designed for road noise control, i.e. for sound waves coming from ground level. NOMINAL DIMENSIONS: height up to 250 mm – length up to 4000 mm – thickness up to 120 mm

  • Stability: this panel is unalterable over time; durability: stainless steel will withstand;
  • Durability: stainless steel will withstand exposure over time to the most extreme weather and climatic conditions.
  • Corrosion strength:Main feature of STAINLESS STEEL;
  • Humidity resistance: Suitable for installation in very damp areas, also in potentially etching saline/brackish environments
  • Easy removal of dirt and graffiti:This panel is extremely easy to clean
  • low maintenance: Thanks to the patented heads and compensators, replacing a damaged panel has never been so quick and easy.
  • Excellent sound absorbance: Absorption class A4 – Insulation class B3, corresponding to the highest performance classes according to UNI EN 1793 standards. This panel is in compliance with the Italian Railway Technical Regulations RFI Italferr ed. 98
