Hammerglass Noise barrier system Post Free (STOLPFRI)

This EPD covers the version of Hammerglass Noise barrier system Post free that is 2,3 meters high.

A complete CE-marked system without posts for mounting in an edge beam on a bridge, on a wall or with a ground foundation. The screen construction consists of 12 mm Hammerglass mounted in a lid steel angle. The Hammerglass panels are bent in three planes. The construction is supported by a 90 degree vertical bend which in addition, complemented by two smaller 45 degree bends top and bottom for extra stability. Each individual Hammerglass panel is fixed at a strong steel angle and anchored in the next panel with Fixpoints. The steel angle consists of a horizontal base and a vertical part with varying height (400-600 mm) adapted to the height of Ham- merglass screen. As the assembly allows, the boards can advantageously be buried in 15-20 cm in macadam / single to prevent sound spread below the screen. Hammerglass boards can be patterned against bird collisions.
