Absorbent-insulating panels
Absorbent and insulating metallic noise barriers consist of a folded or profiled rear box made of aluminum or galvanized steel.
They are filled with a mineral wool of varying thickness and density adapted to each type of use.
The front of the panel is protected by a perforated aluminium sheet.
After manufacture, the product is thermo-painted by polyester coating, completed, as an option, by an anti-graffiti treatment.

Absorbent panels
Our absorbent metallic noise barriers have been specially designed to effectively absorb sound waves in tunnel access and exits.
They are also used as absorbent siding, along traffic lanes, workshops, sports halls, …
They consist of a perforated aluminum sheet, filled with a panel of mineral wool.
After manufacture, the product is thermo-painted by polyester powdering, completed, as an option, by an anti-graffiti treatment.
