SuperPhon Hardface Acoustic Wall Panels for Prisons and Damage-Risk Areas


SuperPhon™ HardFace is a highly sound-absorbent acoustic treatment encased in perforated, galvanised steel, making it suitable for high-traffic areas and environments where vandalism may be an issue, such as prisons, police stations and industrial areas. Visually, the perforated steel casing conveys a strong contemporary aesthetic feel, ideal for residential or commercial applications, which can be powder-coated in any RAL colour to complement any interior. Black or white glass tissue facings or Melinex can be applied to the acoustic core to enhance the product’s appearance and protect from the majority of common substances. Alternatively, a range of coloured fabrics in Cara or Lucia styles can be employed for greater aesthetic flexibility.

Storage and Handling

SuperPhon™ HardFace should be handled with care in order to avoid damage. Panels should be stored flat and covered in a clean, dry, wellventilated area.

Cleaning and Maintenance

SuperPhon™ HardFace is a system that requires virtually no cleaning or maintenance other than light vacuum cleaning with a soft brush attachment at six monthly periods or more frequently if the panels are located in a dusty environment. For other contaminants to the surface of the panels wiping with a clean cloth and detergent solution is all that is required. Fixings should be checked at bi-annual periods and should be tightened if required.
