In general, we associate the term ‘noise pollution‘ with the noise that is generated due to road traffic or industries. Sometimes residential areas are not as far from roads or industrial estates are they should be. It can also occur an excess of noise for various other reasons that can diminish the quality of life, and even the health of the people who live in them. Whatever the focus of the noise is, at Metalesa we have the solution. Depending on the origin of the problem, we can install acoustic screens on the roads or directly surrounding the residential areas. With this aim, it is necessary to carry out an acoustic study to determine the specific area to isolate and therefore where the noise screens should be built. The acoustic study provides crucial information to improve the solution and achieve the planned objectives with an optimised solution.

Except for very obvious cases, noise pollution and its effects on the population have generally been an ignored factor while urban planning in many cities. In Spain many residential areas have such problems due to the settlement of urbanizations in areas close to transport infrastructure or industries. In response to this problem, and lacking the authorities initiative, it is common for residents to create neighbourhood associations that seek for exert advise to make pressure on the public administration and finally resolve their complaints.

Noise pollution in housing estates therefore affects people’s health and the environment in general, fauna and flora. But not only that, it also has economic effects. The price of a home in a residential area with severe noise pollution can affect the price of the property up to 30%, since potential buyers associate noise with a lower quality of life, and therefore are willing to invest less. In case of the appearance of noise after the commissioning of the urbanization, it could be devalued and the investment of the residents very affected.

Urban Noise Screens

Urban noise screens are those that we place as an enclosure for urbanizations and as the main mechanism against noise. The reasons for implanting acoustic screens in housing estates can be diverse: proximity to roads with heavy traffic, proximity to bus or train stops or stations, poorly soundproofed industrial estates, nightlife area…

If the acoustic study shows the convenience of placing screens around the urbanization, our proposal is to place urban screens. These panels for private areas are mainly made up of two pieces:

  • Acoustic panels: These panels make up the absorbent and reflective part thanks to a design that has been used for other environments for many years.
  • Supporting structure: consisting of HEA/HEB-type uprights with hot-galvanized welded base plate and painted with polyester powder paint.

Regardless of their configuration, all the noise screens have been rigorously evaluated in certificate laboratories by the corresponding standards, guaranteeing maximum sound absorption values. Furthermore, at Metalesa we are concerned with both the functionality and the aesthetics of our products. At the same time that it ensures the elimination of the acoustic problem, it allows an excellent integration with the style of the urbanization, for which we adapt our solution to the client’s aesthetic specifications. For example, urban screens can be made of metal, methacrylate, or wood. The metallic ones can be painted depending on the desired colour, by means of a thermo-lacquering process that guarantees a perfect finish of great durability. The supporting structure will be always metallic, so it can be thermolacquered no matter what material has been chosen for the panels.

Description of our noise acoustic screens

As we have already mentioned, if the acoustic study provides this conclusion, we will proceed to install anti-noise screens between the urbanization and the area that acts as the focus of noise pollution. At Metalesa we have various types of acoustic panels:

Metal steel or aluminium screen

We have a wide range of fully effective metal steel and aluminium screen panels to eliminate noise. They are installed and tested on roads across Europe. Its components are the following:

  • Absorbing face oriented to the focus of noise: It is a multi-perforated metallic element, which allows the noise wave to penetrate inside the panel and dissipate in the absorbent material.
  • Acoustic insulation: The interior of the panels is composed of rockwool of different thicknesses and densities depending on the acoustic parameters to be achieved. This material allows the dissipation of sound wave energy thanks to its fibrous and elastic nature.
  • Reflective face: The rear reflective face is unperforated and leaves a gap in between with the rockwool, creating an acoustic chamber that reflects the sound waves back into the absorbent material.
  • Supporting structure: It is made up of HEA/HEB type uprights, with hot-dip galvanized welded base plate and painted with polyester powder paint.

This type of acoustic screens allow effective noise isolation for the well-being of the residents of any urbanization, in addition to standing out for its excellent landscape integration and durability.

Green Panel

Green panel is a type of acoustic screen that integrates perfectly with the landscape and allows generating a greener environment thanks to the possibility of planting vegetation on them. In addition to rockwool, it also has an integrated green plastic mesh that facilitates the growth of vegetation on both sides.

Methacrylate Panel

Methacrylate Panel can be installed both on road and railway infrastructures and in housing estates, and can be both transparent and have drawings as required. Like the other panels, they are easily installed and very resistant, so they hardly require maintenance. They are composed of a polymethacrylate sheet and a supporting structure with a hot-welded base plate and painted with polyester powder paint.

Wood Panel

The wood acoustic panels are also filled with rock wool. They also have the advantage of being able to combine horizontal and vertical tables, achieving different aesthetic effects.

Summing up, the quality of the environment in which we live our lives is increasingly an objective that we must all empower to ensure the well-being of our people. Noise pollution is one of the factors that can most negatively affect this objective, which is why at Metalesa we take care of the process from very beginning to its end, from the acoustic study to the manufacture and installation of the acoustic screens, from the problem analysis to the solution in place.
