Safety

Transparent noise barriers made from PLEXIGLAS SOUNDSTOP^® offer drivers greater safety than non-transparent systems.

Prevention of tunnel effect

With its high transparency, PLEXIGLAS SOUNDSTOP^® lets drivers look at the changing landscape. This successfully prevents the tiring and dangerous feeling of driving through a tunnel. Moreover, the high light transmission ensures that no harsh shadows are cast on the road and that the lighting conditions remain constant. The eye is not obliged to adjust to the effects of light and dark all the time.

Resistance to Stone Impact according to EN

PLEXIGLAS SOUNDSTOP^® is approved as safety glass and meets all the requirements of EN 1794 for the resistance of transparent noise barrier elements to stone impact.

The high break resistance of PLEXIGLAS SOUNDSTOP^® ensures that the sheets are not destroyed by stones or gravel projected by passing vehicles, nor by stones thrown from outside the barrier.

Sliver retention

When noise barriers are installed on bridges, it must be ensured that the noise barrier presents no risk to persons or objects under the bridge. No fragments may be allowed to fall from the barrier after an accident, for example.

The German regulation ZTV LSW 06 and EN 1794 state that "if brittle materials or materials whose embrittlement cannot be excluded (e.g. plastics) are to be used, these elements or their fragments must be reliably secured by means of restraint structures."

The polyamide threads embedded in PLEXIGLAS SOUNDSTOP^® GS CC correspond to these restraint systems, because they successfully prevent sheet fragments from falling.
