Rockwool insulation
rock wool & mineral wool manufacturer and supplier from China
Rock wool, also known as mineral wool, is a type of insulation material made from natural rock or stone, primarily basalt, as well as recycled slag and glass. It is produced by melting the raw materials at a high temperature and then spinning the molten material into thin fibers. These fibers are then compressed and bound together to create insulating products with various applications. Rock wool is known for its excellent thermal and acoustic insulation properties. need inquiry, contact us now!
the types of fire bricks
Rock wool, or mineral wool, comes in various types and forms to suit different applications and insulation needs.
Acoustic Panels
- Density: 60-150 kg/m³
- Raw materials: Basalt
- Thickness: 25-150mm
- Asbestos: 100% Non Asbestos
- Function: Thermal insulation, Sound absorption
Rock wool has good sound-absorbing properties, making it an excellent choice for noise reduction in both residential and commercial buildings. It is used in walls, ceilings, and floors to dampen sound
