Autex Acoustics
Notes: 100% polyester fiber (PET) fin on an aluminum channel/clip system, 2400mm (94.5in) length x 300mm (11.8in) nominal depth, 24mm gauge. Coverage figure is one-sided face area per fin (length x depth), since fins are linear/modular rather than flat panels. Official Autex data sheet (ISO 354, Univ. of Auckland) lists NRC by spacing for 24mm fins at 300mm depth: NRC 1.05 at 100mm centres, 0.90 at 200mm centres, 0.85 at 300mm centres (value used here). 12mm fins at same depth/spacing range from NRC 0.75-1.00; Frontier Axis (150mm deep) is NRC 0.70. ASTM E84 Class A fire rating.
