Acoustic Grid Foam
For a crisp and tidy approach to sound deadening, the Acoustic Grid panels have a tiled aesthetic for aiding in the reduction of bouncing sonic waves. Sold in an interlocking two-panel set, one panel features a border, while the other is edgeless. The coverage offered by these panels makes them a fantastic choice for effectively treating large spans of space at once. The "bordered" panel of Grid foam will have a "stand-out" design, while the edgeless panel has a "cut-out" design. If you ever decide to expand your treatment, you can trust that these patterns will stay the same.
