Mineral wool tiles feature an internal porous fibrous structure that effectively absorbs sound waves, thereby reducing indoor noise and echoes. Their Noise Reduction Coefficient (NRC) typically ranges from 0.50 to 0.90; standard models are suitable for general applications, while high-absorption models (NRC > 0.70) are ideal for professional acoustic environments such as theaters and recording studios.
Composed primarily of inorganic mineral fibers, these tiles are non-combustible materials that meet the GB 8624 Class A fire safety standard; they do not burn during a fire and effectively inhibit the spread of flames .
The porous structure of mineral wool tiles effectively minimizes heat transfer, enhancing indoor thermal insulation and helping to reduce energy consumption for air conditioning.
With a low density-typically between 280 and 450 kg/m³ (some products range from 180 to 450 kg/m³)-these tiles reduce the load on the building structure while maintaining high rigidity and resistance to deformation.
While standard mineral wool tiles are highly hygroscopic, moisture-resistant versions undergo special coating treatments to ensure stability in humid environments. Antibacterial variants incorporate nano-antibacterial agents to effectively prevent mold and inhibit bacterial growth, making them suitable for settings such as hospitals and laboratories.
The surface of the tiles can be finished using processes like knurling, embossing, perforating, and spraying to create diverse patterns and textures-such as "caterpillar," "starry sky," cross-floral, and walnut-grain designs. Available in finishes including white, wood grain, and metallic, they offer excellent decorative appeal.
Manufactured primarily from industrial by-products like slag, these tiles represent a resource-recycling product; many are free from harmful substances such as asbestos and formaldehyde, and the material itself is recyclable. Common nominal sizes for square mineral wool panels include 300×600 mm, 600×600 mm, and 600×1200 mm; linear panels come in various specifications, such as 300/400/600 mm × 1200/1500/1800 mm; and common thicknesses include 9 mm, 12 mm, 14 mm, 15 mm, 18 mm, and 20 mm. Actual dimensions are slightly smaller than nominal dimensions to allow for installation clearance.
