Noise control with sound-absorbing material starting from a thickness of 1.3mm. A peaceful sound space with Poal *Available for purchase from a single sheet.

"POAL" stands for Porous Aluminium, a metal porous sound-absorbing material created by sandwiching aluminum non-woven fabric with expanded metal and rolling it. 【Features】 ◇ Outstanding weather resistance Since it does not use adhesives (binders) to maintain its shape, it does not degrade from UV rays like glass wool. It dries quickly when wet, and its sound-absorbing performance is restored. Water-repellent treatment is unnecessary. ◇ Heat resistance Aluminum is a non-combustible material as defined by the Ministry of Construction Notification No. 1400. It has excellent heat resistance and is safe even in high-temperature conditions. ◇ Excellent workability It is easy to drill and bend, resistant to vibrations, and there is no concern about cracking or falling off. ◇ Recyclable Made entirely of aluminum, it is recyclable. It is an eco-friendly sound-absorbing material with no environmental burden upon disposal. ◇ Decorative It can be painted and accommodates color coordination. Awarded the Special Prize at the 18th Invention Awards Received the Excellence Award at the 8th Ota City Small and Medium Enterprises New Products and New Technologies Competition Patent obtained (Japan, USA, Australia, UK, Canada)

Introducing Poal, which has excellent sound absorption characteristics and outstanding durability and weather resistance. Here are some examples of its implementation.

Bashamichi Station opened in February 2004. With an average daily ridership of 36,421 people (in 2015), it is a vibrant station that is beloved as a base for sightseeing in Yokohama. The dome ceiling installed above the ticket gate absorbs unnecessary noise and helps to reduce the hustle and bustle, while simultaneously creating a space that feels anything but an underground station. Additionally, its excellent design expresses the concept of "contrast and fusion of the past and the future." Moreover, Poal is active in various locations. There are many examples that we cannot introduce here, so if you are interested, please feel free to contact us.

Introducing Poal, which has excellent sound absorption properties and outstanding durability and weather resistance. Here are some case studies of its implementation.

◆ Case Study of Domestic Railway Vehicle Manufacturers When we received an order for subway vehicles in Hong Kong, Poal was adopted. It is used to reduce noise from the air conditioning equipment installed under the floor and to lessen running sounds. Poal leverages its excellent weather resistance, good drainage properties, and lightweight characteristics to expand its presence globally. Additionally, Poal has also been adopted in some Shinkansen vehicles. It suppresses the sound from exhaust ducts, creating a comfortable environment from unseen locations. Poal is active in various other locations as well. There are many cases that we cannot introduce here, so if you are interested, please feel free to contact us.

18th Invention Award - Special Prize Winner 8th Ota City, Tokyo - Excellent Award at the Small and Medium Enterprises New Products and New Technologies Competition Patent Obtained (Japan, USA, Australia, UK, Canada) "POAL" stands for Porous Aluminium, a metal porous sound-absorbing material created by sandwiching aluminum non-woven fabric with expanded metal and rolling it. 【Features】 ◇ Outstanding Weather Resistance Unlike glass wool and similar materials, it does not degrade due to UV rays as it does not use adhesives (binders) for shape retention. It dries quickly even when wet, and its sound-absorbing performance is restored. Water-repellent treatment is unnecessary. ◇ Heat Resistance Aluminum is a non-combustible material as specified in the Ministry of Construction Notification No. 1400. It has excellent heat resistance and is safe even in high-temperature conditions. ◇ Excellent Workability It is easy to drill and bend, resistant to vibrations, and there is no concern about cracking or falling off. ◇ Recyclable Made entirely of aluminum, it is recyclable. It is an eco-friendly sound-absorbing material with no environmental burden upon disposal. ◇ Decorative It can be painted and supports color coordination.

Introducing Poal, which has excellent sound absorption properties and outstanding durability and weather resistance. Here are some examples of its implementation.

◆Case Study of Waste Treatment and Recycling Operators The noise generated by the crushing machines for home appliances exceeded 100dB, making communication between workers impossible. Measurements of the sound sources revealed that the noise from the mill part of the crusher, the area around the feed opening, and the sound from the sorting machine's exit, along with echoes from the walls, were particularly loud. By covering the crusher with soundproof enclosures made of Poal and installing sound-absorbing panels on the nearby walls, we achieved a significant noise reduction from approximately 105dB to about 87dB. 'Poal' can be easily bent and punched, allowing it to be processed into shapes that fit the site. *105dB is comparable to the sound of a car horn from close range, while 87dB is similar to the noise level inside a crowded train. ◆Case Study of a Major Construction Company 'Poal' was adopted as the material for soundproof walls used in construction projects. When a soundproof wall approximately 60cm high is installed on top of a 3m high soundproof enclosure, it achieves a noise reduction effect equivalent to that of a 6m high soundproof enclosure (note). Since the height of the soundproof enclosure can be kept lower, it creates less sense of pressure on the surroundings and is easier to install. 'Poal', being thin, lightweight, and highly weather-resistant, does not suffer from performance degradation due to water absorption, making it ideal for outdoor use.

Introducing Poal, which has excellent sound-absorbing properties and outstanding durability and weather resistance. Here are some examples of its implementation.

The large roof underside of Nissan Stadium (Yokohama International Stadium) has adopted Poal as the ceiling material for the corridor. It suppresses the cheers of the large crowd and prevents sound leakage to the outside, while clarifying conversations and announcements within the venue. Poal, which is thin and lightweight, maintains its sound-absorbing performance even when exposed to wind and rain, making it ideal for outdoor use. Even after 20 years since installation, it is still in active use. With outstanding durability, Poal withstands long-term use and maintains excellent sound absorption. Additionally, Poal is active in various other locations. There are many examples that we cannot introduce here, so if you are interested, please feel free to contact us.

Introducing Poal, which has excellent sound absorption characteristics and outstanding durability and weather resistance. Here are some examples of its implementation.

We have adopted Poal at a large convention center in Yokohama. In exhibition halls where large-scale events are held, moderate reverberation is necessary, but if it goes too far, it becomes very noisy, making it difficult to hear even the necessary sounds. Therefore, by using Poal on the walls of the exhibition hall (with a total area of 20,000 square meters) and the ceiling of the entrance, we can adjust the reverberation sound. This allows for a moderate echo while ensuring that conversations and announcements are clear. In addition to its sound absorption properties, Poal is also highly regarded for its excellent durability. The Poal introduced during the expansion in 2001 is still actively in use even after 16 years. With outstanding durability, Poal withstands long-term use while maintaining excellent sound absorption. Furthermore, Poal is active in various other locations. There are many cases that we cannot introduce here, so if you are interested, please feel free to contact us.
