What is the difference between rock wool board core material and regular rock wool board?

1. Structural Form

Rock Wool Board Core Material: Typically refers to the rock wool used as the core in sandwich panels or other composite boards. It usually comes in block or strip form, with fiber orientation perpendicular to the upper and lower surfaces of the sandwich panel. In the panel, the core is bonded to the two outer skins with adhesives, forming an integrated structure.

Regular Rock Wool Board: Made by directly compressing rock wool into board form. Its structure is relatively simple, generally consisting of a single rock wool material without composite layers.

2. Application Scenarios

Rock Wool Board Core Material: Mainly used in various sandwich panels, such as rock wool sandwich panels for steel-structured factories, temporary modular buildings, roofs, walls, and ceilings or partitions in clean rooms. In these applications, the core and outer skins work together to provide excellent overall performance, meeting requirements for thermal insulation, fire resistance, and structural strength.

Regular Rock Wool Board: Widely used for external wall insulation, interior partitions, ceilings, and other building applications. It is also applied in industrial areas requiring high thermal insulation, such as cold storage or equipment rooms, and can be used for pipe and equipment insulation.

3. Price Considerations
Due to differences in production processes and applications, rock wool board core material is generally sold as part of a sandwich panel, and its price is influenced by the overall cost of the panel. Regular rock wool board pricing depends mainly on specifications, density, and quality, making its price structure relatively independent.
