Tecnowall concrete panels

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
