It is recommended that AF-90 be applied to a maximum thickness of 25mm, as greater applications do not result in any significant acoustic performance beyond an NRC ( Noise Reduction Coeff) of 0.90.
Typically, an optimum thickness of 15mm (NRC 0.65) applied to 70% of available ceiling areas, would offer brilliant reverberation control in most open plan office situations, including Call Centre.
Efficient application is achieved by a crew consisting of 3-4 workers, consisting of: One Sprayer, one Machine Feeder and one (or more) Cleaners to maintain good site housekeeping.
AF-90 is available in an illuminating “Vivid White”, and may be colour dyed on Site, or over painted with an acrylic paint, to achieve a specific final look.
This is best used in areas where a chic smart looking acoustic ceiling / soffit is required- making it highly suitable for restaurants, meeting rooms, open plan offices, libraries and Call Centres.
AF-90 may be used in any building, with or without a sprinkler system complying with Specification E 1.5 in accordance with Specification C 1.10 Table 2.
