Bestefa produces lightweight concrete blocks, of size 50 cm by 25 cm, more in thickness, to be used both in the construction of acoustic barriers scratch, both in the field of acoustic remediation, of pre-existing works, being able to be fixed easily and fast, the vestments of the presidium works.

The geometry of the blocks has been carefully studied in order to obtain good acoustic performance (sound absorption class: A3 and A4).


In detail, the Bestefa produces two types of blocks, different for the surface geometry invested by sound waves:

  • gauge blocks with a cane: BS 018C;
  • blocks with polygonal shape: BS 018P.
