Rockboard 60 have a dimension of 24" x 48" x 2" inches. This product is manufactured by Roxul. It is rigid mineral wool board similar to Owens Corning 705 at a density of 6 pounds per cubic foot.

Rockboard is rigid but not very strong, similar to Styrofoam in strength.

Rockboard 60 is a great option for acoustic projects that require a rigid material.

I showed my home theater installer the ATS website and he noted the specs on the panels are virtually the same for ones costing easily 2 or 3 times the price.
