Transparent Noise Barrier Panels

Transparent noise barrier panels

Calvero transparent noise barrier panels enable the construction of modern transparent noise protection barriers, which ensure a high level of protection from noise in the vicinity of roads and railways tracks. They are suitable for the construction of noise barriers which protect the residents living alongside roads or railways.

Owing to its transparency, such noise barriers leave the drivers feeling unrestricted and not visually detached from the landscape.

Calvero transparent noise barrier panels are long-lasting, easy to assemble, while the maintenance is quick and simple. They can be installed as standalone units or in combination with Calvero aluminium noise barrier panels and other types of noise protection panels.

Transparent noise barrier panels are also well suited for noise reduction in industrial plants in order to reduce noise pollution of surrounding areas.

Acrylic sheets (PMMA sheets)

– Standard thickness (12, 15, 20 and 25 mm)

– Large dimensions (width up to 2,050 mm, length up to 6,000 mm)

– Wide range of transparent and non-transparent colors

– Available extruded (XT) sheets, cast (GS) sheets or acrylic sheets reinforced with black or transparent polyamide fibers.

 

Polycarbonate sheets (PC sheets)

– Standard thickness (8, 10, 12 in 15 mm)

– Large dimensions (width up to 2,000 mm, length up to 6,000 mm)

– Wide range of transparent colors

 

All of the transparent materials built into Calvero transparent noise barrier panels meet the requirements of the EN 1793 and EN 1794 standards.

Aluminium profiles

Side aluminum profiles

Enable the installation of transparent noise barrier panels between HEA/HEB 100, 120, 140, 160, 180, 200 and 220 columns.

Longitudinal aluminium profiles

Are of utmost importance for meeting the required static and dynamic characteristics of transparent panels.
A wide range of longitudinal aluminium profiles enables the production of an optimal transparent panels which meets the static and dynamic requirements.

Longitudinal and side aluminium profiles are screwed to each other which enables simple servicing in case of damage to the panel.

 

Wide selection of colors

Aluminium profiles are protected with polyester colors. A wide range of colors is available according to the RAL scale.

 

Sealing rubber profiles

 Installation

The panels are suitable for installation  on flat solid surfaces. The mounting is fast and simple as the panels need only be inserted between HEA or HEB metal columns.
Installation of transparent noise barrier panels requires the use of a crane. Protective polyethylene film, used to protect sheet from damage during installation, needs to be removed from the acrylic or polycarbonate sheets immediately after installation.

Safety

Installation of  steel ropes can prevent transparent sheets from falling out of the aluminium frame in case of a vehicle crashing into the noise barrier.

Certificates

The acoustic and non-acoustic properties of the noise barrier panels have been tested at accredited testing institutions. Calvero noise barrier panels are in compliance with the requirements of the EN14388, EN1793 and EN1794 European standards. The panels are also affixed the CE marking and a declaration of performance.
