Wall cladding in facades and tunnels is one of our most demanded services both nationally and internationally, and at the same time one of the most unknown. For this reason, in this article we want to tell you about the great advantages that wall coverings have and what is the difference between cladding on the façade and in tunnels.

Wall cladding in tunnels

In this case, it is a wall cladding made of galvanized steel sound-absorbing panels, specially designed to deal with noise pollution derived from road and rail traffic, both inside and at tunnel entrances. At the customer’s choice, galvanized steel panels can be filled with rock wool, a material with a high sound absorbing capacity that facilitates the rebound of acoustic waves inside, thus trapping much of the sound.

Sometimes, poor tunnel lighting poses a greater risk to drivers. In this sense, the installation of our wall cladding on the concrete walls of the tunnel brings luminosity to the interior, facilitating vision and increasing safety. In addition, any additional signaling or lighting system can be installed on our cladding.

Characteristics and elements of the panels for sound absorbing tunnel coating.

We have several standard construction solutions, configured thanks to the experience of having carried out numerous projects that has helped us to optimize the design and its features.

Our team of engineers studies each project and of steel with the client’s specifications, defines the best technical solution. Typically, the cladding has the following elements:

  • Panels: made of corrugated and galvanized steel sheet. They can be perforated in case of acoustic absorption requirements. There may be a single front panel or front and rear panels. At the customer’s request, its finish can be thermo-lacquered in different colors from the RAL chart.
  • Paneles: realizados con chapa de acero grecado y galvanizado. Pueden ir perforados en caso de haber requerimientos de absorción acústica. Puede haber un solo panel delantero o paneles delantero y trasero. A petición del cliente, su acabado puede ser termolacado en diferentes colores de la carta RAL.
  • Rock wool: This material is used to absorb sound waves generated by transport systems.
  • Supporting structure: It is a wall anchoring system using adjustable rods made up of profiles that allow the panels to be adapted to walls with almost any type of irregularity. We have several bearing systems, in each project the most suitable will be chosen depending on elements such as the state of the wall or the type of coating required.

Advantages of panels for sound absorbing tunnel lining

  • Corrosion resistance: we have different solutions depending on the environmental specifications in the area, including up to C5. In addition to being made with galvanized materials, if the client wishes, we can apply primer and / or thermo-lacquering techniques, which protect the coating from the consequences of the passage of time and adverse weather conditions.
  • As we have already mentioned, this type of cladding fulfills an important acoustic function, and this is precisely its main advantage.
  • Easy installation due to its lightness. High productivity in assembly.
  • Its maintenance and repair is also easy in case of damage by accident.
  • It is a non-flammable coating.
  • It fulfills an aesthetic function as the customization of the color is possible, and it also brings light, unlike the concrete walls to which we are accustomed.

Wall cladding integrated into building facades

In order to minimize the noise pollution produced by environmental noise, such as traffic or the bustle of people, at Metalesa we manufacture and install panels that function as wall cladding on facades, and that are integrated as an acoustic screen in the building .

Below, we show you some images of one of our acoustic wall cladding integration project on the façade of the Atlético Baleares football field. In this case, the panels have been used both to isolate noise from the field, and to prevent noise from the street from breaking into the sports facility.

On the other hand, this product offers a great opportunity to improve the aesthetics of a building through an elegant and quality solution that, thanks to the customization options that we offer at Metalesa, will be able to show off the corporate colors. In this sense, a change to the façade by means of a cladding of these characteristics can make an installation become “something iconic” of an area and give it a certain prestige. Without a doubt, the Atlético de Baleares field is proof of this.


Characteristics and elements of panels for sound absorbing coating integrated in facades

In the same way as in the case of tunnels, we have several standard construction solutions applicable to the integration of acoustic coatings in facades. Our team of engineers will define the best technical solution according to the customer’s specifications.

The elements that make up this solution are usually the same as in the case of tunnels. The main difference is usually in the bearing structure, which must be defined ad-hoc for each project, since it is not the same to anchor acoustic panels to a low-rise wall but with great vibrations due to circulating traffic, than to a wall. of a high-rise building and normally without these vibrations.

Advantages of wall cladding on facades of urban buildings

The facade is the exterior wall of the enclosure or vertical closure that surrounds. It is one of the most important elements of the construction along with the roof. Both act as a barrier against external weather factors

Providing the facades of the infrastructures in urban areas with a facade cladding is essential, as it is one of the most important elements of its construction due to its acoustic, aesthetic and climatic function.

Acoustic and mechanical properties of our panels

The acoustic properties of our panels have been evaluated according to EN 1793-1 standards, obtaining maximum acoustic absorption and insulation values. Any acoustic product manufactured by METALESA SEGURIDAD VIAL complies with the requirements established for CE MARKING in compliance with annex ZA of the EN 14388 standard.

Regarding mechanical behavior, the panels are tested according to the EN 1794-1 standard, having obtained very high loads in tests carried out in accredited laboratories.
