The INSO ROAD acoustic barriers used in road and railroad transport are of various
types:
Metal barriers which are subdivided into: barriers in steel, barriers in aluminium
Transparent barriers made of: glass, polycarbonated, polymethylmethacrylated
Compound barriers made of opaque and transparent parts
Barriers in wood
Barriers in light concrete with caulking
The anchoring of the support for the base curb is guaranteed for use with galvanized or stainless steel screws whose diameter is to be determined by calculating their placement at the proper axial distance between
them.
The heights of these barriers come in multiples of 500 mm and up to an interaxial distance between supports equal to 4000 mm.
The insulation of the area around the vertical joints, between the support and the panel, is ensured by a rubber gasket in EPDM placed on the top of the
panels.
For these Barriers INSO ITALIA has performed tests in an accredited laboratory in accordance with the ISO rules and has also obtained acoustical barrier certification under examination by the
D.I.E.N.C.A. of Bologna for the ITALFERR branch and using the
ADRIENNE method.
