IKING GROUP-INSULATION AND ACOUSTIC SOLUTION FOCUS
High-density rock wool board is a non-combustible insulation material widely used in data center environments where fire safety and system reliability are critical. Designed to withstand high temperatures, it helps prevent fire spread, reduce heat transfer, and protect critical IT infrastructure. With excellent thermal insulation, sound absorption, and long-term durability, it is an ideal solution for server rooms, equipment areas, and HVAC fire protection systems.
Fireproof Rock Wool Board for Data Centers
1. Product Overview
Data centers have dense server racks and complex electrical systems. Fire risks and thermal control are key to operational safety and cost. Common ignition causes include electrical short circuits, equipment overheating, lithium-ion battery failures, and human error. Our fireproof rock wool board is a high-performance inorganic insulation material for data centers, providing stable fire protection, thermal insulation, and durability to protect infrastructure and ensure uninterrupted operation.
2. Fire Performance
This rock wool board has an A1 non-combustible fire rating, a core part of passive fire protection systems. It blocks flame spread, slows heat transfer, and protects structural integrity in fires. For data centers, even short downtime brings heavy losses; our A1 fireproof board reduces outage risks and meets strict safety standards.

Key Advantages
-A1 Non-Combustible: Non-flammable, no toxic smoke at high temperatures, meets global fire standards.
-High Heat Resistance: Stable at 650–1000°C, keeps its shape under extreme heat.
-Good Thermal Insulation: Low thermal conductivity reduces cooling loss, lowers PUE, and energy use.
-Sound Absorption: Dampens fan and equipment noise in server rooms.
-Moisture Resistance Durability: Water-repellent, resists mold, ensures long-term performance.
Typical Applications
-Data center interior and exterior wall insulation
-Server room and equipment hall fire barriers
-HVAC duct fireproofing and insulation
-Cable rooms, electrical rooms, and battery compartments
-Modular data center cleanroom walls
