According to structural calculations individual wall panels up to 6 m and with a minimum deflection can be used in strong winds also. At the length of 6 m we can save on a number of columns and the cost of ground works up to one third of the cost. Other noise barrier systems usually allow for the maximum field length of 4 m.
The Liadur noise barrier system is environmentally friendly. The wall panels can be recycled. Recycling is usually not possible due to the preservatives used in the wood systems.
The degree of sound absorption is dependent on the thickness of absorbing layer and the waveform. The achieved values place the noise barrier components in the category A2, A3 and A4.
Compared to plastic and other acoustic systems, the Liadur walls are resistant to high temperatures and fire.
The molding technology we use enables the creation of virtually any shapes of the sections (trapezoidal, triangular and curved). Plastic and aluminum systems are in this respect limited.
Coloring of the sections already in the production or spraying on the site can achieve a variety of color shades.
The rough surface of sections is a good precondition for easy growing of climbing plants and greenery. To grow greenery, most other systems require a support structure.
Due to the characteristics and structure of the absorption layer made of the Liapor aggregates, the harmful effects of humidity and exposure to chemical de-icing substances are not visible on the Liadur walls. At the same time the free moisture penetration into the spaces between the grains allows for the self-cleaning effect on the surface of the absorption layer. For this reason, the Liadur noise barrier system does not have to be covered on the top and it is therefore completely maintenance-free.
Installation of the walls is carried out without the use of fasteners (screws, nails, etc.) - the two plates are connected already at the factory, thus eliminating their connecting and the threat of loosening of fasteners and the risk of falling plates.
The system offers two-sided absorbing walls, again in different surface versions.
The Liadur noise barriers reduce both the noise pollution caused by the road traffic, but they can also significantly contribute to the reduction of environmental pollution. Population of the significant part of the Czech Republic is exposed to high noise pollution and air pollution especially in big cities and near main roads, caused by the road traffic and exhaust emissions of the nitrogen oxide NOx.
A completely new and technologically interesting solution on how to reduce emissions of air pollution is the Liadur system using the TX Active technology. It uses the natural process of photocatalysis, the action of light which leads to degradation of many substances, including airborne pollutants. Since under natural conditions the process of photocatalysis is slow, the reaction rate can be accelerated by using a photocatalyst, which is titanium dioxide TiO2. That is activated by the UV-A radiation and can break down the gaseous nitrogen oxides NOx.
Ideal places for applying this technology are the concrete noise barriers, which not only reduce the noise in the area, but also significantly improve the quality of air.
