Compared to other acoustic systems, the Liadur noise barriers have a number of advantages:
Long life span
- According to studies, the life span of the Liadur walls is up to 50 years. This is more than three times the lifetime of plastic or wooden noise barriers.
- Durability of concrete noise barriers is not affected by high temperatures or UV radiation, as is the case with plastic noise barriers.
- In addition, the concrete layer is not subject to moisture absorption and mildew, such as the mineral wool used as an absorber in the plastic, aluminum and wood systems.
Saving one third of the cost of columns and ground work
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.
Possibility of recycling
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.
High level of sound insulation
- DLR > 45 dB
- Sound insulation with other materials is also lower due to their lower base weight.
Optional level of sound absorption
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.
Heat resistance of concrete sections
Compared to plastic and other acoustic systems, the Liadur walls are resistant to high temperatures and fire.
Wide selection of architectural designs
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.
Color variety
Coloring of the sections already in the production or spraying on the site can achieve a variety of color shades.
The ideal surface for climbing plants
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.
Maintenance-free operation
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.
Easy installation
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.
Noise absorption on both sides
The system offers two-sided absorbing walls, again in different surface versions.
Other advantages over other systems
- No risk of bird collisions such as with the walls made of transparent plastic or glass.
- No risk the walls can be stolen, such as with the walls made of aluminum.
The Liadur noise barriers can reduce exhaust emissions
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.
