NOISE - LE DIFESE® WALL

Le Difese® WALL is the sound-absorbing cladding made of PC-ABS, PC or PP.‎ Anti-Noise systems in recycled, recyclable and innovative material WALL is a system based on high-end plastic sound-absorbing elements to be mounted on anodised aluminium rails, fixed on a load-bearing structure (concrete, masonry, plasterboard, metal, etc.‎).‎ The pyramid-shaped sound absorber originates from recycled plastic compound (> 60%) very UV-resistant and 100% recyclable.‎ Among the first acoustic barriers in Europe to have EPD environmental certification.‎ The system is equipped with a 80-mm-thick sound-absorbing polyester mat (density up to 80 kg/m3) achieving high values of acoustic absorption.‎ The mat is placed inside a “shell” (size: 500x500mm; thickness: 3,5mm) that is perforated over 35% of its surface.‎ The sound-absorbers elements are linked by a smart and exclusive coupling system, specially designed to allow a suitable thermal expansion, ensuring the stability and correct geometry of the panel.‎   Applications ROAD, RAIL AND AIRPORT INFRASTRUCTURES Le Difese WALL is an effective solution to reduce noise pollution in communication infrastructures (roads, highways, railways, airports, etc.‎).‎  The sound-absorbing barrier allows to obtain an acoustic absorption level up to 19dB (class A5), according to UNI EN ISO 354:2003, UNI EN 1793-5 and UNI EN 1793-1:2017.‎ INDUSTRY AND CIVIL CONSTRUCTIONS WALL is also successful in the industrial and civil sector for: • Reducing noise in productional environments, to contain it within the regulatory limits (Legislative Decree 81/2008, Italy); • Absorbing noise from industrial sites within the regulatory limits as shown  on Table B, DPCM 14/11/1997 and its subsequent amendments, Italy; • Thermal insulation of buildings thanks to the low conductivity guaranteed by its internal PET (polyester) mat.‎ Made of recycled plastic material The sound-absorbing barriers are produced by means of injection moulding of PC-ABS, PC or PP, also based on recycled compounds (>60%).‎ Entirely recyclable “Le Difese® Wall” is made of 100% recyclable plastics (shell, sound-absorbing mat).‎ Paint-free anti-reflective finishing “Le Difese® WALL” does not require any coating or painting process: the plastic material is mass colored, avoiding heavy pollution and dispersion of paint in the environment.‎ Acoustic and mechanical properties according to European Standards “Le Difese® WALL” barriers meet all recent European Standards on acoustic and mechanical performance, long-term durability, stability requirements, general safety rules as well as environmental standards and product specifications.‎ Further info from manufacturer on LE DIFESE® WALL NOISE
