Durable rigid sound-absorbing material that reduces urban noise.
Poasel is a cement-based rigid sound-absorbing material that exhibits high sound absorption due to the structural partial bubble wall interconnection. Its sound absorption performance has an absorption rate unmatched by other rigid sound-absorbing materials, demonstrating a reverberation room absorption rate of 0.85 to 1.00 at 500Hz to 2kHz when in contact with a rigid wall of 50mm thickness, and it also performs well in the low-frequency range. This material has sound absorption performance comparable to the best fiber-based sound-absorbing materials and excels in durability, safety, and maintenance. 【Features】 ○ Sound absorption performance ○ Durability ○ Water resistance ○ Wind resistance ○ Heat resistance For more details, please contact us or download the catalog.

Company information
Nihon Concrete Industry is a company that creates the foundation to support people's lives. Are you aware that the buildings you are currently in—homes, offices, skyscrapers, and facilities—have a "foundation" that is never visible from the outside? That foundation, buried deep underground, is essential for protecting people's safe and secure lives. We, at Nihon Concrete Industry, handle various concrete products in different fields, including foundation piles (concrete piles) that support buildings, concrete poles, civil engineering products, and construction products. In addition to thorough quality control, we are committed to contributing to the creation of a safe, secure, and prosperous society through concrete, while also considering global expansion and environmental conservation.
