with expanded clay or with mineral wood fibres The factors that mostly affect the efficiency of acoustic barriers are sound-insulation linked to the masses involved and sound-absorption linked to the porosity and shape of the materials. The noise barrier consists of two layers, one of normal reinforced concrete with a density of 2200-2400 kg/mc, having a supporting function, one of light porous concrete with a density of 900-1100kg/mc. FIP and TECNOACUSTICA offer a noise barrier consisting of a 100mm-thick prefabricated structure of self-stable reinforced concrete and a Greek-fretted facade made of lightweight concrete panels with expanded clay and/or mineral wood fibres for a total thickness of 120mm.
The standard length of panels is 292 cm, which permits a typical centre distance of 3 metres. In terms of height, standard measurements of individual panels are 1.5 metres and 2 metres. Panels are fitted onto metal frames that are dimensioned so as to withstand the stress resulting fro

Another type of noise barrier solution is the use of typical building materials like concrete. Noise barriers TYPES: 6W64 TECNOWALL green wall TECNOWALL sound-absorbing concrete and lightweight concrete panel expanded clay or mineral wood fibres.

The 6W64 wall consists of very thin reinforced concrete elements that, by alternating voids and fills** during fitting, create a set of pots to be filled with soil; more than 50% of the front surface consists of exposed soil which is arranged according to its natural sloping angle. The foundation elements rest on a concrete slab or on prefabricated elements; they are fitted by alternating right and left elements** and fixing is ensured by steel bars. The fill-in soil shall be green, rich in humus or in any case so as to ensure taking root of vegetation. The soil filling and compacting (to be accomplished by poleaxe) shall be performed every other layer of the structure, in order to let the soil fill completely the space available. It is preferable to fit an automatic sprinkler system during the mounting phase: the low cost is appropriately offset by the saving of maintenance costs and by the advantages in terms of sound-proof performance and appearance. The 6W64 wall can be placed bo
