Reinforced Transparent Acrylic Sheets Designed for Acoustic Barriers
Plazit-Polygal, a Israeli manufacturer of plastic and acrylic sheets, has launched the Plazcast SMR reinforced transparent acrylic sheets, designed for use as acoustic barriers in buildings, on road and rail bridges, and at airports.
Plazcast SMR cast acrylic sheets are reinforced with embedded metal wires to provide the extra strength required for the sheets to conform to the most stringent mechanical and impact tests for sound barriers. This is particularly important for sound barriers where safety is a critical consideration such as alongside bridges. The sheets, which come in a range of colors, are reinforced with both rigid and elastic 2mm stainless steel cables and wires, making them significantly stronger and resistant to impact while preventing shattering. As the cables do not significantly reduce the transparency of the panels they are suitable for use in buildings, in bridges and in barriers designed to allow visual access. As stainless steel is used for reinforcement, the strength of the Plazcast SMR sheets does not degrade over time. Ten year old sheets will be as strong as new sheets.
The panels, which are manufactured at the Plazit-Polygal facility in Spain, can be machined and shaped by hot bending according to architectural, aesthetic and acoustic needs. They can be easily cleaned and repaired by conventional means. They can be produced in whatever color is desired and the sheets size and thickness can be tailored as required. Standard sheets are 2050 x 3050 mm and thicknesses of 15, 18, 20, 22 and 25 mm are available.
