The Panacor AC100 Steel Acoustic Barrier is a noise barrier specially designed to reduce the noise generated by road and rail traffic.
Its design criteria use the noise signature of road and rail traffic as a reference, subsequently adapting the barrier’s noise abatement properties to optimise
its overall efficiency.
Likewise, the design seeks to optimise the panel’s mechanical performance by fitting it with two deep guide rails to improve its mechanical ability to withstand wind pressure.
The noise barrier can be made of grade DX51D+Z200/275-NA galvanised steel plating in accordance with standard UNE EN 10142, or with AA 3105 H24 aluminium sheet, either of which has a powder coating finish, customised as required in any shade on the RAL colour chart.
The inside of the composite panel is made up of sound-absorbing mineral wool of various densities and thickness depending on the precise noise-abatement properties required.
Thus, panels comprise four metal parts. The inner face (directed at the noise source) has holes over 36% of the surface area to provide for noise absorption, while the outer face is a plain, reﬂective panel. Barrier panels are installed between vertically arranged HEB/HEA proﬁles to achieve the desired overall height, in 300, 400 or 500 mm modules, and the distance between posts can be varied.
Acoustic and Mechanical Features
Reference Standards: UNE EN-EN 1794-1:2003; UNE EN-EN 1794-2:2003; UNE EN 1793-1:1998; UNE EN 1793-2:1998
The barrier support structure is made up of HEA/HEB metal profiles with a welded baseplate, both grade S275JR according to standard EN 10025.
Baseplates and profiles are galvanised and powder coated in accordance with the requirements of standards EN 1461 and EN 15773.
The profile posts are anchored to the foundations by means of anchor bolts of varying diameters, lengths and grades depending on the specific requirements of each individual project.
The barrier panel is designed to be mounted without any need for rivets or bolts and thus can easily be installed manually by two people with the need for electricity.
This rivet and bolt free solution is highly suited to situations where fatigue problems may appear, for example in hi-speed railway constructions projects.
Anti-rust treatment. The powder coating treatment that PANACOR AC100 noise barriers are given makes them extraordinarily resistant to adverse weather effects, to heat and deterioration due to exposure to the sun, and provides excellent anti-corrosion properties, all of which makes for an end product that requires practically no maintenance.
