EXAMPLES OF OUTDOOR USE
Poal is composed of non-woven aluminum fibers sandwiched between aluminum expanded metals and it shows good properties under the strict conditions such as outdoor use because of its excellent anti-corrosion and drainage characteristics.
Stadium
PLACE: The back of the main roof
PURPOSES: Decrease of noise level and reduction of reverberation
Poal’s light weight allows it to be used under the roof deck of a stadium where it produces a more comfortable environment by decreasing noise level and reducing reverberation.
Cooling Towers / Outdoor Units of Air Conditioning Systems
COOLING TOWERS
PLACE: Noise barriers and noise reducers on the top of noise barrier
PURPOSES: Decrease of noise level
Expressway
PLACE: Noise reducers on the top of noise barriers of the expressway.
PURPOSES: Decrease of the traffic noise generated on the expressway.
PLACE: The back of the expressway
PURPOSES: Decrease of the traffic noise generated between the back of the expressway and the expressway.
Poal has excellent drainage and no lowering in sound absorption efficiency due to rainfall, therefore it is used widely as the sound absorptive material for the expressway.
Racehorse Training Racecourse
PLACE: Inside of the fence of racecourse
PURPOSES: Decrease of noise generated from the training of horses.
Poal is light a material and has excellent drainage of water, therefore it dose not deteriorate sound absorptive properties.
