Rock wool ceiling is a flexible material used for interior decoration. It has a very soft texture and rich colors, which can soften the overall space atmosphere. In addition to beautiful appearance, it also has flame-retardant, sound-absorbing, sound-proof, moisture-proof, mildew-proof, anti-bacterial, oil-proof, waterproof, dust-proof, anti-fouling, anti-static and anti-collision functions. 
1. Rock wool ceilings have good thermal insulation properties and when used in air-conditioned places, it could reduce influence of the outside world on the indoor temperature, thereby effectively saving energy. It is generally used as suspended ceilings. There are many types and can be produced as modeling ceilings or flat ceilings. The modeling ceilings could be any size, any color, any shape for ceiling decoration. 2. It has good heat insulation performance under high and low temperature conditions, does not burn, and does not produce harmful gases. It can effectively isolate sound impurities and improve speech intelligibility to become a common material for interior decoration. Rock wool ceiling has the advantages of sound absorption, flame retardant heat insulation, moisture resistance, simple construction, good stability and impact resistance. Rock wool panels have excellent sound absorption performance. The back-mounted cavity of building ceilings is usually larger than 200mm. The low-frequency sound absorption coefficient will be greatly improved due to the cavity, so rock wool ceiling can reach the full frequency band with strong sound absorption effect. 3. Compared with ordinary similar products, rock wool ceiling board has the characteristics of good sound absorption, high heat preservation, high flame retardancy, strength, excellent flatness, and beautiful finish, convenient installation, good moisture-proof performance, no deformation under any damp condition, easy to operate, easy to cut, good fire and heat insulation performance, anti-bacterial and anti-mildew, the product can be recycled. Rock wool ceiling is very light, and a full-band strong sound-absorbing material, therefore, it is suitable for large-span buildings such as stadiums, exhibition halls, large shopping malls and high-noise workshops as sound-absorbing ceilings, which can effectively reduce indoor reverberation and make the environment quieter.
