Melacoustic building insulation Foam boasts an exceptionally high porosity rate of over 99%, which, through elongating the thermal conductivity path infinitely, endows it with outstanding thermal insulation properties. Additionally, the material exhibits stable physical and chemical properties, allowing it to maintain its insulation characteristics continuously in various environments over the long term. With its inherent flame retardancy and excellent secondary processing capability, the material can be applied in various forms for thermal insulation purposes in venues such as hotels, schools, hospitals, sports arenas, and auditoriums.
