The list of perforation options are standard and should be used as a guide for choosing performance criteria and aesthetic requirements.
Noise reduction requirements may be specified for your project. This can be achieved by adding acoustical absorbing material.
A variety of the perforation pattern have been tested per ASTM 423-99A. Reports may be available upon request for professionals. The average NRC is .75 for perf. patterns 5% or greater, using non-woven backing.
Selecting Acoustical Absorbing Material
• Non-woven acoustical fabric laminated to back side of panel
• Average NRC .75
• Class A Rating- ASTM E84
• Colors: Black, Grey, Brown, Light Brown
Requires a minimum of 6”-7” deep plenum space to achieve results. Not recommended as sole acoustical backing for wall panels.
Other Acoustical Options
• 1” x 1.5# Fiberglass Insulation .80 NRC
• 1.5” x 1.5# Fiberglass Insulation .85 NRC
• 2” x 3# Fiberglass Insulation .95 NRC
•Some perforation patterns may result in deflection beyond manufactures recommendation. Consult with factory on best pattern suited for panel size and finish criteria
