Melacoustic® melamine ceiling and wall noise reduction materials are composed of lightweight flame-retardant porous melamine foam with an open porosity rate exceeding 99%, combined with various panels such as porous metal plates and porous wood grain boards. These materials possess inherent flame retardancy and excellent sound absorption and noise reduction capabilities, effectively capturing sound waves above 200Hz with a capture rate of over 95%. They are primarily used for acoustic treatment in venues such as hotels, schools, hospitals, sports arenas, auditoriums, and office buildings, as well as for noise reduction in factory equipment and air conditioning plenums.
