PANACOR MD11 ACOUSTIC PANEL
The PANACOR MD11 acoustic screen is specially designed to reduce the noise produced by road traffic.
The criteria used in its design take the acoustic signature of road traffic as the reference on which to adapt the panel’s noise abatement characteristics to optimise its efficiency. At the same time, its mechanical performance has also been optimised by measuring its mechanical strength against wind pressure in real scale tests.

HOW THE SCREEN IS BUILT
The panel comprises a rear wall of 21 mm wide, tongue-and-groove slats with a density of 550 kg/m3, and an inner structure made of 50×50 mm wooden battens, 50 mm thick, 100 kg/m3 dense Rockwool, a 1.2 mm thick, 50 kg/m3 polypropylene mesh and horizontal slats made of wood measuring 95mm x 21 mm, with a gap of 50 mm between each. These acoustic panels are made of Sylvester pine wood from Sweden or Finland, treated to class ‘4’ in vacuum autoclave with steam injection.

The support structure for the fence is made up of HEA/HEB metal posts on a welded base plate, both complying with grade S275JR according to standard EN 10025. Posts and base plates are galvanised and heat spray coated to meet the requirements of standards EN 1461 and EN 15773.
Posts are anchored to the foundations using anchor rods that vary in diameter, length and grade depending on the specific requirements of each individual project.
