NRC > 1.0. NRC above 1.00 is expected for thick or suspended products — under ASTM C423, edge diffraction lets a finite sample absorb more sound than its flat face area implies.

Notes: 100% PET felt (55% recycled), bi-layer 9mm, Class A (ASTM E-84). NRC 1.30 at 2-3/4", tested 4'x4' Type J mounting (>1.0 = ASTM C423 edge-effect absorption). Sizes: 47" dia circle or 47x47 in square (15.34 sq ft).
