POAL is a completely new type of sound absorber compounded with non-woven aluminum fibers and aluminum expanded metals, which offers a variety of excellent properties.

In Japan and in other nations, fibre glass and rock-wool have been typical sound absorbents in the past. UNIX POAL is completely new type of sound absorber compounded with non-woven aluminium fibres and aluminium expanded metals, which offers a variety of excellent properties.

But against the background of recent technical innovation, a change in our needs and increase in environmental problems, sound absorbing materials have been diversified.

Classifying the sound absorbing materials according to the sound absorption mechanism, the porous type used the soft porous materials and the resonator type used the hard porous materials are the mainstream. But recently the membrane type such as Filva-T and Filva-M invented by UNIX has been practical application.

Outstanding Features

  • Excellent sound absorptive properties
    Poal is a completely new type of sound absorber compounded with non-woven aluminum fiber and expanded metals and it shows superior broad-banded sound absorption.
  • Lighter than aluminium yet sturdy
    Porosity of Poal is about 40%, so the specific gravity of it is about 2/3 of aluminum plate. As the material is solid metal like plate and has strong resistance to wind pressure, there is no need to provide front cover, such as perforated metal.
  • Good weather resistance and non-flammability
    Weatherproof and fireproof tests show that Poal has a long life and non-flammability.
  • Recycling capability
    Poal is made from pure aluminum, so it can be melted again for other aluminum products.
  • Good drainage and free from deterioration
    Poal drains water well, thus unlike fiberglass, no lowering in sound absorption efficiency due to water.
  • Excellent workability and easiness of handling
    Poal can be formed into a curved board and cylinder. Drilling, nailing, bolting and other mounting works are easy to do. Unlike fiberglass, Poal is not dispersed in the form of tiny fibers. Thus no problem of pollution arises and handling is easy.
  • A variety of applications
    Poal can be used for a variety of applications such as the sound absorber for reverberation control in a room, noise barrier and noise reducer for prevention of noise pollution. The ornamental uses are also available after color coating.
  • Poal contains no organic binder
    Poal is a porous aluminum board by rolling non-woven aluminum fibers with expanded metals. It is not susceptible to loss of strength over time because it contains no organic binders.
