Absorbent-insulating panels
The panel consists of polymethacrylate (PMMA) plates inserted into an aluminum structure.
This tubular frame incorporates a mineral absorbent protected by a perforated metal sheet to absorb incident sound waves.
PMMA plates can be transparent, opaque, screen-printed and also colored.
After manufacture, the structure is thermo-painted by polyester powdering, completed, as an option, by an anti-graffiti treatment.
TRA 01
Panels slipped horizontally between HEA profiles.
Maximum length: 4000 mm // Maximum height: 2000 mm // Thickness: 150 mm
Composition :
- Polymethacrylate methyl (PMMA) plates – different thicknesses, colors and finishes available
- Aluminium structure thickness : 150 mm
- Absorbent mineral wool integrated into the structure
Acoustical characteristics:
Laboratory values
- Sound absorption: DLα,NRD = 6 dB according to EN 1793-1
- Insulation: DLR = 31 dB according to EN 1793-2
TRA 02
Panels slipped horizontally inside and in front of HEA profiles.
Maximum length: 5000 mm // Maximum height: 2000 mm // Thickness: 145 (inside) to 160 mm (in front of)
Composition :
- Polymethacrylate methyl (PMMA) plates – different thicknesses, colors and finishes available
- Aluminium structure thickness : 145 to 160 mm
- Absorbent mineral wool integrated into the structure
Acoustical characteristics:
In situ values
- Acoustical reflection: DLRI = up to 3 dB (depending on the number of vertical poles) according to EN 1793-5
- Insulation in the middle of the panels: DLSI,E = 33 dB according to EN 1793-6
- Insulation at the right of the poles: DLSI,P = 36 dB according to EN 1793-6
Insulating panels
The panel consists of polymethacrylate (PMMA) plates that are either fixed between clamps (TR 01) or inserted into a tubular aluminum or steel frame, or slipped between HEA profiles (TR 02).
In both variants, appropriate clamps and EPDM seals ensure a perfect acoustic sealing.
PMMA plates can be transparent, opaque, screen-printed and also colored.
After manufacture, the aluminum structure of the TR 02 is thermo-painted by polyester powdering, completed, as an option, by an anti-graffiti treatment. In the case of a steel structure, it is previously hot-dip galvanized.
