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.
Benefits
- High transparency
- Resistance to high static and dynamic loads
- High sound insulation (up to 32 dB)
- A wide range of colors
- Easy assembly and maintenance
- High resistance to UV rays
- High resistance to ageing and corrosion
- Possible installation into HEA and HEB 100-220
- Possible production of standard and custom dimensions
- Possible combining with other types of noise barrier panels
- Custom additional treatments (print, anti-graffiti protection, bird stickers, steel ropes…)
Consisting parts
Calvero transparent noise barrier panels are made of:
- Extruded aluminium profiles
- Transparent acrylic sheets, polycarbonate sheets
- EPDM sealing rubber
1 – Side aluminium profile
2 – Longitudinal aluminium profile
3 – Transparent filling (acrylic or polycarbonate sheet)
4 – HEA/HEB column
L – Panel length
H – Panel height
Transparent materials
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
“U” sealing rubber profiles
They are inserted in each joint between the transparent sheet and the aluminium profile.
“U” EPDM sealing rubber profiles prevent water retention in the panel and reduce transmission of vibrations onto the transparent sheet.
O” sealing rubber profiles
They are inserted into vertical aluminium profiles.
“O” EPDM sealing rubber profiles prevent water retention in the metal HEA/HEB columns and reduce the transmission of vibrations onto the transparent panel.
Installation demonstration
1 – Side aluminium profile
2 – Longitudinal aluminium profile
3 – Transparent panel filler (acrylic sheet, polycarbonate sheet)
4 – HEA/HEB column
5 – “U” sealing rubber
6 – “O” sealing rubber
Combinations
Calvero transparent noise barrier panels can be installed as standalone units or in combination with Calvero aluminium noise barrier panels.
1 – Transparent sheet
2 – Longitudinal bottom aluminium profile
3 – Aluminium noise barrier panel
4 – Longitudinal upper aluminium profile
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.
