"Measurements are done according to a standard test method such as ASTM C423 or ISO. In some cases, the measured sound absorption coefficient is greater than 1.00. As recommended by the test method, these values are reported as measured and not adjusted. Differences in coefficients of less than 0.15 are not significant."

"The SuperChunk is accomplished by cutting up mineral fiber panels into triangles and then stacking them so as to fill the entire corner from floor to ceiling. Panel thickness is immaterial, but the thicker they are the fewer you have to cut, and thicker ones may be cheaper per volume.
