GRAMM Green noise barrier is a mineral wool-based noise barrier, which offers good absorption and insulation values. The barrier panels consist of metal mesh covered with a PE net.

The PE net can be supplied in different colours. All galvanised steel material can be powder coated, on request.

The steel net has a rectangular mesh pattern so that vision through the barrier is not obstructed.

After installation, the barrier can be covered by different climbing plants, as the nature of the barrier supports plant growth.

By using plants the barrier helps create a clean and healthy environment, converting polluting carbon dioxide into oxygen. In this way it is ideal for use along highways, railways and local roads.

The barrier itself is constructed out of fully recyclable materials. It provides a visually attractive system.

Gramm Barrier Systems is the only noise barrier specialist in the country to give a 30-year guarantee on all acoustic fencing, acoustic barriers and noise barriers.

Barriers are designed to be maintenance-free for the full 30 years.

All materials and installations are to such a high standard that the company is the only noise barrier specialist to have all works backed and insured by the government.
