Rock Wool Board for Structural Fireproofing and Industrial Equipment
Product Overview
Rock wool board is a sturdy, semi-rigid insulation panel manufactured from natural basalt rock fibers. It features stable structural performance, excellent thermal insulation, superior fire resistance, and effective sound absorption.
This rigid insulation board effectively reduces building energy loss, suppresses indoor and equipment noise, and blocks fire spread, solving common thermal, acoustic and safety problems in construction and industrial environments.
It is widely applied for wall, ceiling, roof and equipment insulation, ideal for building fireproof partitioning, HVAC systems and general industrial thermal preservation projects.
Xiaolong customized rock wool board supports adjustable density, thickness, dimensions and surface facings to meet different project standards. We provide flexible MOQ, OEM service and professional technical selection guidance for global engineering and wholesale orders.
Product Features
1. Rigid and shape-stable
The board maintains a flat shape during handling and installation, ensuring uniform insulation thickness across the installed area. Its rigid structure is suitable for applications where the panel must hold its form without sagging.
2. High-temperature resistance
Made from natural volcanic rock, the board can withstand continuous operating temperatures up to approximately 600–700°C depending on density and product formulation.
3. Thermal and acoustic insulation
The porous fiber structure helps reduce heat transfer and absorbs part of the airborne sound energy. Actual performance depends on density, thickness, and installation conditions.
4. Easy to cut and fit
The board can be cut to size using standard tools and can be friction-fitted between framing members when dimensions match the cavity size. Additional fixing may be required depending on the installation system.

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.
