APP Profiled Acoustic Liner
Acousticabs APP Liners provide a cost effective, attractive and robust finish for noise absorbing wall treatments.
Liners are designed for a variety of situations in industrial and commercial premises where control of reverberant noise requires acoustic treatment of large surfaces.
Typical applications include acoustic linings to gyms, school dance rooms, corridors and studios.
Alternative versions are suitable for industrial use within manufacturing areas, or for environmental noise control in conjunction with acoustic screening.
APP Liners can also be fitted as a very robust perforated acoustic ceiling – installed either direct to the soffit or as a suspended profiled acoustic ceiling.
APP Liners are manufactured from steel and aluminium sheet which is specially perforated and profiled to maximise the sound absorption characteristics of the acoustic core material.
The Liners are overlapped and mounted on rails fixed to the wall, allowing rapid treatment of large areas.
APP Liners are fitted over a suitable acoustic core material faced with a black acoustic fleece. For exterior applications, a water repellent facing is used.
Treated areas are trimmed with aluminium, steel or timber cappings.
APP Liners are available in two forms – the curved C18 profile and the deeper J32 rectangular profile.
The noise absorption coefficient is given below, measured in accordance with ISO 354 (reverberant room method).
