The Polygon noise reducer is installed at the top of the noise barrier or other items. NOMINAL DIMENSIONS: length: 3.000 mm – height: the polygon consists of a octagonal circle with diameter 400 mm. Featuring special sound-absorbing properties, it allows the user to increase the virtual height of the noise barrier savings in terms of working surface panelling.
CONSTRUCTION FEATURES:
- Outer element: composed of metal sheet components (aluminium or steel), bended, painted or pre-painted and also perforated
- Inner element: helical tube in galvanized steel
- sound-absorbing material: a sound-absorbing slab in rock wool or polyester inserted between the outer and inner element
- joint covers: made of pre-painted, bent sheet straps of width 120 mm, fixed by rivets
- support structure: the noise reducer is fixed to the underlying panels by suitable sized support structure.
ADVANTAGES:
- Aesthetic: the panel form makes the insertion into the surrounding environment particularly pleasant.
- durability: the upper horizontal side of the octagon is made of a full metal sheet which limits the infiltration of rain water inside the device instead the perforated sides makes it possible to eliminate humidity from the sound-absorbing slab
- mechanical resistance: the symmetrical and regular panel form ensures the uniform and mechanical strength, independently of the wind load direction
- high acoustic performance: tests confirm the effectiveness of the octagonal noise reducer; the noise reducer installation at the top of the noise barriers is equivalent to results obtained with the installation of panels 80 cm high.
PERSONALIZATION:
Application of photovoltaic surfaces on the full metal sheet
