Manufacturer of rock wool board insulation material with a fire rating of Class A? Rock wool board, as a widely used insulation material in the fields of construction, industry, and ships, has attracted much attention due to its excellent fire resistance. The fire rating of rock wool board is a key factor to consider in industrial design and construction, especially in pipelines, kilns, and industrial facilities where fire safety is crucial. Rosewool Insulation Refractory Co.,Ltd. Rock Wool GB8624 A-level/A1 level non combustible, all using basalt raw materials, 1450 ℃ high-temperature melting production, with fire detection reports and type inspection certificates;
                                                                                     

Definition and advantages of rock wool board

Rock wool board, also known as rock wool insulation board, is a board made of basalt as the main raw material, which is melted and fiber-reinforced at high temperature, and then solidified with an appropriate amount of binder. The combustion performance level of rock wool board is determined through combustion performance tests, and different levels of rock wool board need to be selected according to the specific requirements of the building in practical applications
  1.  It has an A1 fire rating and is effectively flame retardant.
  2. Low thermal conductivity and good insulation effect.
  3. The internal fiber structure is effectively affected by noise.
  4. Chemical stability and no corrosion.

Application areas of rock wool board:
  •  Insulation for boilers and equipment pipelines in various industries such as petroleum, chemical, metallurgical, power, textile, etc;
  •  Insulation and sound absorption for partition walls, ceilings, and interior and exterior walls in the construction industry;
  • External insulation for tanks, boilers, large steel structures, and glass curtain walls with large flat and curved radii;
  • Thermal insulation and fire partitions for ships.
                                                                   
Construction steps for exterior wall insulation rock wool board:

1. Rust removal and anti-corrosion
Rust removal of equipment cylinder, application of anti rust primer, and dry and rust free metal surface.
2. Binding and fixing
3. Seam treatment

Fill the board joints with crushed rock wool, and seal the joints with aluminum foil tape to prevent moisture under high temperature conditions.
4. Construction of outer protective layer

Tunnel insulation hydrophobic rock wool board pit avoidance guide, be sure to avoid pits

Tunnel insulation hydrophobic rock wool board pit avoidance guide, be sure to avoid pits! The tunnel is a century old project, and once there is a problem with the rock wool board, replacing it is more than ten times more expensive than installing it. So during acceptance, not only is the thickness and flatness measured, but also the bonding strength pull-out test should be conducted. In the special environment of tunnels with high humidity, large temperature difference, and extremely strict fire prevention requirements, the selection of hydrophobic rock wool board is directly related to the quality and safety of the project.
