Noise barrier composed of transparent PMMA (polymethylmethacrylate) panels with frame and gaskets. The extruded or pure PMMA panel can be transparent or colourless and has been approved by RFI/ITALFERR. The sheets are completed by a perimeter frame in self-passivating Corten steel or galvanized painted steel on 3 or 4 sides. NOMINAL DIMENSIONS: length: 3000 mm – variable height: from 500 to 2000 mm – sheet thickness: 15, 18, 20, 25 mm
The technical features of the PMMA panel are compliant to UNI EN ISO 7823 part 1 and 2. The EPDM gaskets guarantee perfect sealing and the plate-frame system absorbs the expansion due to dynamic and thermal factors. The panels can be inserted between HEA- or tubular columns. Anchoring system for foundation, bolts and nuts are suitable to the predicted barrier-height.
Personalization: possibility to install transparent, coloured sheet with and without silk-screen prints
Resistance and durability: reinforced sheets with polyamide wires increase, in case of impacts, the panel resistance and panel safety is guaranteed; sheet bending obtained by cold processing or thermoforming;
Perfect acoustic insulation: Sound-insulation class B3 according to UNI EN 1793
“Lip” type seal also acting as an electric insulator between frame and profile
