Rock Wool Board Insulation for Building and Industrial Applications
Product Overview
Rock wool board is a semi-rigid insulation panel made from mineral rock fibers, offering thermal insulation, fire resistance, and sound absorption for building and industrial applications.
Its rigid structure makes it suitable for wall, ceiling, roof, equipment, HVAC, and other insulation systems where stable panel installation is required.
Jinsimai supplies Rock Wool Board in different densities, thicknesses, dimensions, and facing options. Customized specifications, OEM orders, and wholesale quantities are available according to project requirements.

Product Features
Rigid and shape-stable
The rigid structure helps maintain a flat shape during handling and installation, supporting consistent insulation coverage.
High-temperature resistance
Rock wool can withstand high temperatures, with the applicable temperature range depending on product formulation and installation conditions.
Thermal and acoustic insulation
Its fibrous structure helps reduce heat transfer and absorb sound. Actual performance depends on density, thickness, and installation conditions.
Easy to Cut and Install
The board can be cut to required dimensions using suitable tools and fitted into different insulation systems. Additional fixing may be required depending on the application.

FAQ
Q1. Can rock wool board be friction-fitted between studs?
Yes. When board width matches the cavity size, it can be friction-fitted. Additional mechanical fixing may be required for ceilings or high-vibration applications.
Q2. Is rock wool board water-resistant?
Rock wool board is not waterproof. It may absorb moisture if exposed to water or high humidity. Proper weather protection or cladding is required for outdoor or damp environments.
Q3. What is the maximum operating temperature for rock wool board?
Continuous operating temperature up to approximately 600–700°C, depending on density and formulation. Confirm specific temperature requirements when ordering.
Q4. Can rock wool board be used for structural fire protection?
Yes. It is commonly used for structural steel fireproofing and fire-rated wall assemblies. Please contact us for application-specific fire performance guidance.
Q5. How does rock wool board compare to glass wool board?
Rock wool board offers higher temperature resistance (600–700°C) and is commonly used for industrial and fire protection applications. Glass wool board is typically used for building insulation at lower temperature ranges.
