ZAK - Factory of Acoustic Structures
“Avantgarde Engineering Depot” together with the Russian Factory of Acoustic Structures (ZAK) - the unique in the North-western region certificated producer of noise protecting screens of the patented development - offers you acoustic noise protecting screens.
Noise protecting screens are made for protecting population from harmful sound influence outgoing from the highways of railways and motorways, building areas, industrial equipment and other sources of noise.
The original structure of noise protecting screens is developed together with the scientists of department of ecology and safety of vital functions of the Baltic state technical university of "Voenmekh" (BGTU) and with the Scientific and technical center "Ecology" and patented on territory of a Russian Federation.
The complex noise protection system AcRan is a ready-made structure consisting of supporting bars and acoustic curtain, in its turn presented by the system of horizontal types and acoustic panels.
The acoustic panels functionally are divided into: noise absorbing opaque and noise reflecting translucent. For corps making of noise absorbing acoustic panels are used the followings materials: zincked steel, zincked steel with poliurethan coverage "Pural", stainless steel, aluminium.
The structure of noise protecting screen is sertificated Конструкция in the system of Gosstroya of Russian Federation, and all materials used for his making have hygienical and fire certificates.
The acoustic panels by installation are set in horizontal types, which in its turn, are set and fixed in a vertical slot which width can be settled. For prevention of bending of horizontal type, in case of hard foundation absence, under acoustic curtain, in flight between bars is set a supporting profile.
Advantages of noise protecting screens:
- high acoustic efectivity (insulation index of air noise up to 30 dba)
- high degree of corrosion protection (hot zincing)
- flexibility of structure - a spacing of supporting bars from 0,5 m to 4,0 m; height to 6 m
- possibility of choice of different architectural solutions
- a wide range of colour silutions (up to 25 colours)
- setting simplicity - load lifting mechanisms are not required;
- price reduction by setting - during setting on soil band foundation is not required;
- maintainability (ready-made);
- long working life;
- irrevocable container;
- low price
Moreover noise protecting screen is not only affective barrier for for distribution of sound-waves, but also a physical barrier for distribution of such contaminating components, as harmful chemical matters, weighed particles, heavy metals and other.
