1. Introduction to Mineral Wool Sound Absorbing Panels Mineral wool sound absorbing panels are a versatile and high-performance material used in interior design for both aesthetic and functional purposes. These panels offer excellent sound absorption, fire resistance, thermal insulation, and decorative appeal. They are ideal for ceiling and wall applications in various spaces such as hotels, theaters, shopping malls, offices, studios, computer rooms, and industrial buildings. By controlling reverberation time, these panels enhance indoor acoustics, reduce noise levels, and create a more comfortable living and working environment. Additionally, their non-combustible nature ensures compliance with strict fire safety regulations. 2. Shapes and Surface Treatments of Mineral Wool Sound Absorbing Panels The surface designs of mineral wool sound-absorbing panels are diverse, offering strong visual appeal. One popular type is the "caterpillar" panel, which features a textured surface with holes of varying depth, shape, and size. Another variant, known as the "starry" panel, has a different pattern of apertures on its surface. There's also a three-dimensional version created through milling, giving it a striped or patterned appearance. The embossed type, formed by stamping, comes in various decorative patterns such as central flowers, cross patterns, and walnut motifs, making it an attractive choice for ceilings and walls. 3. Cost and Installation of Mineral Wool Sound-Absorbing Panels When installing mineral wool sound-absorbing panels, a common setup involves using a 5cm keel (either wooden or made of light steel), filled with 5cm thick, 1.3kg/m² gradient sound-absorbing cotton, and covered with a layer of gypsum board. For general residential use, 5cm high-efficiency sound-absorbing cotton is usually sufficient. Gypsum boards can typically reduce noise by 20-30 dB. For special requirements, two layers of 5cm thick gradient cotton can be used, achieving noise reduction of up to 30-40 dB. As for cost, the reference price for a mineral wool sound-absorbing panel ceiling includes about 10-20 yuan for the keel per square meter, 5 yuan for the gradient sound-absorbing cotton, and another 10-20 yuan for the gypsum board. The total cost depends on the size of the area being treated. These panels not only provide effective noise control but also add a modern and elegant touch to any space. Cut-off Saw is a power tool which is designed to cut hard materials, such as materials, such as metals, tile, and concrete. The cutting action is performed by abrasive disc, similar to a thin grinding wheel. Cut off saw,Chop Saws,Metal Cut Off Saws,Cordless Cut-Off Saw AWLOP CO.,LTD , https://www.awlop.com
