Acoustifiber sound wallAll AcoustiFiber walls meet or exceed all AASHTO and DOT guidelines.

Each wall is made of interlocking tongue and groove fiberglass reinforced plastic planks set into concrete, steel, wood or FRP columns.

The internal web design of the AcoustiFiber plank minimizes deflection and allows each wall section to span up to 24 feet, greatly reducing the number of columns and caissons required for each project.

The 12- inch high design minimizes the number of planks required per section while the tongue and groove configuration strengthens the assembled wall and eliminates the possibility of any gaps between stacked planks.
