Made by high-temperature melted mineral wool pressing, the fiber structure is uniform, and the noise reduction coefficient (NRC) can reach 0.85, which can effectively reduce the reverberation time of public spaces. It has a fire resistance duration of 1 hour in accordance with ASTM E119 standards, and the fire rating is Class A. Its moisture resistance is better than ordinary mineral wool boards, and the surface is treated with an antibacterial coating, which can effectively inhibit bacterial growth. It is installed by hanging on ceiling keels, compatible with standard ceiling keels, and has the characteristics of light weight and high strength, with a weight of only 150-200kg/m³, reducing the ceiling load.
Available sizes are 600mm×600mm and 1200mm×600mm, with thickness options of 15mm and 20mm. The apparent density is 150-200kg/m³, noise reduction coefficient NRC is 0.85, sound absorption performance complies with GB/T 20247-2006, fire resistance duration is 1h, moisture resistance complies with GB/T 17657-2013, environmental protection grade is E0. Each carton contains 16 Square Meters of boards.
It is suitable for ceilings and wall decorations of airport terminals, high-speed rail stations, school classrooms, hospital wards and commercial shopping malls. It can effectively improve the acoustic environment of the space, and at the same time meet the fire protection requirements of public spaces, complying with domestic and international fire acceptance standards and improving the safety and comfort of public spaces.
