Product Description

The metal noise barrier ALPHAfon-MB is composed of a galvanized metal sheet at the external side and perforated metal sheet for the internal side.

The external faces can be painted in any RAL color. The two ends of the metal barrier are properly formed (male-female) in order to achieve perfect sound sealing but also to improve its bending strength.

Internally, it is filled with sound-absorbing material, mineral wool, hydrophobe, with appropriate density, cover with thin glasswool cloth.

  • Noise protection from traffic noise (cars, trains, noisy machines, chillers, cooling towers etc)
  • Easy to install

The metal barriers ALPHAfon-MB can be installed sliding on iron profile, from special formed double T (HEA), which are appropriatly fixed to the basement.The metal barriers can also be installed vertically with the appropriate support at the top and the bottom.

In the case of road noise barrier, it is recommended to build an appropriate concrete wall at the bottom of the barrier. The height and the length of the metal barrier can be determined by our company using a special PC program, in order to estimate the noise reduction and decide on the best technical-economical solution.
