A cement-based rigid porous sound-absorbing material with a high sound absorption rate and excellent durability for outdoor use.
"Poissel" is a cement-based rigid porous sound-absorbing material that exhibits high sound absorption properties due to its partially interconnected bubble walls. Its sound absorption performance has a higher absorption rate compared to other cement-based rigid porous sound-absorbing materials, showing a sound absorption coefficient of 0.85 to 1.00 in a reverberation chamber test at 500Hz to 2kHz with a thickness of 50mm in direct contact with a rigid wall, and it also performs well in the low frequency range. It has sound absorption performance comparable to excellent fiber-based sound-absorbing materials, along with superior durability, safety, and maintenance characteristics. 【Features】 ■ Sound absorption performance comparable to fiber-based sound-absorbing materials ■ Achieves durability for long-term use ■ Resistant to rainwater and free from concerns about freeze damage ■ No need for surface protection materials like perforated metal ■ Strong against wind pressure, suitable for silencers and ventilation shafts *For more details, please refer to the PDF document or feel free to contact us.
