Gramm's ALUSoundBlok aluminium acoustic barriers consist of high-density mineral wool encased in aluminium panels, providing a lightweight and corrosion-resistant sound-absorbing barrier. They are perforated to protect and maintain the sound-absorptive capability of the fill material.

Individual panels in the system can easily be removed and replaced as they are not bolted, welded or fastened to each other, or to the support posts.

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