Gramm presents the innovative fusion of a road safety barrier with a special noise absorbing element VRSSoundBlok. With an overall height of 900 mm, the system is just as tall as other common, modern guardrail systems – and yet reduces noise levels in protected areas significantly!

80 % of all traffic noise on roads comes from the interaction of the asphalt and the wheels of passing vehicles. With a sound source that low, there is no need for a massive barrier to block the noise, if a screen can be brought close enough to the traffic. The solution is the noise absorbing safety barrier.

The noise absorbing guardrail system is equipped with unique perforated steel beams and special panels with stone wool filling from the market leader ROCKWOOL, that allows high noise reduction levels and impressing results in test according to the European Norm EN 14388.

Apart from its noise absorbing abilities, it is also a fully functional vehicle restraint system, crash tested to the European Norm EN 1317. All steel parts are hot-dip galvanised for maximum life span and enduring performance.
