We offer a complete catalogue of acoustic barriers. These panels are made with metal, aluminium, methacrylate, concrete, vegetal and wooden. The following images explain these screens.

Metallic acoustic barrier

The metallic acoustic barrier is composed of a framework with a specific design capable of withstanding high loads of wind. That can be of steel or aluminium with different thicknesses whose interior contains sound-absorbing material. Its core is made of rock wool with different thicknesses. The final colour can be chosen from RAL chart and, as a new system, we can offer GRAFFITI-PROOFING PAINTING service.

Acrylic acoustic barrier

The acrylic acoustic barrier is composed of a methacrylate panel o transparent polycarbonate that could be colourful or without colour. This panel has acoustic insulation and we could adapt a vinyl with any shape and colour to get a better integration with the environment.

Green acoustic barrier

The vegetal acoustic barrier accomplish a double function: to absorb noise and accomplish with a good aesthetics to blend with the environment. These kinds of panels get a better integration with the environment.

Timber acoustic barrier

The timber acoustic barrier is composed of wooden slats which fit into steel cross sections that are affixed to the concrete floor. These are wedge with wooden struts that allow the adjustments for our client requirements. We get a soundproofing effect with wool rock inside the wooden slats.

Curved metallic acoustic barrier

The curved metallic acoustic barrier is composed of a metallic framework which it had been adapted by bending activities that adapt a better aesthetic result for vehicles viewers and pedestrian viewers. Inside the panel, we can find a soundproofing material composed or rock wool. The client can choose a colour from RAL chart and it can be the same that the flat panel displays.

Concrete acoustic barrier

The concrete acoustic barrier provides stability and tough because of his composition. The concrete can be split in two layers, one soundproofing whose texture is porous to get a less spread of noise, and a second concrete layer that ensures the stability of the element. This screen accomplishes with the ideal acoustic functions in urbanizations, roads and railways.
