What Temperature Does ROCKWOOL Burn? Understanding ROCKWOOL's Fire Resistance

Introduction to ROCKWOOL and Fire Resistance

ROCKWOOL, also known as stone wool insulation, is widely recognized for its outstanding fire-resistant properties. Understanding what temperature ROCKWOOL burns at is crucial for industries requiring reliable thermal insulation that also prioritizes safety. As a leading manufacturer, FUNAS offers high-quality rock wool products designed to perform efficiently in extreme conditions, making them ideal for demanding applications such as petrochemical plants, metallurgy, and refrigeration.

What Temperature Does ROCKWOOL Burn?

ROCKWOOL is composed mainly of basalt rock and recycled slag, which are melted at high temperatures and spun into fibers. This composition gives ROCKWOOL its exceptional fire resistance. Typically, ROCKWOOL does not burn because it is made from non-combustible materials. It has a melting point of around 1,177 °C (2,150 °F) and can withstand continuous exposure to temperatures up to approximately 700-1,000 °C (1,300-1,832 °F) without melting or catching fire.

More importantly, ROCKWOOL acts as a fire barrier, providing critical passive fire protection. The material does not contribute to flame propagation or emit toxic gases when exposed to fire, making it a safe choice for fire-sensitive environments.

How ROCKWOOL's Composition Ensures Fire Resistance

ROCKWOOL’s ability to resist fire derives from its raw materials: natural basalt rock and slag, both inorganic and highly heat-resistant. Unlike organic fiber insulations, such as fiberglass that can degrade or release hazardous fumes, ROCKWOOL fibers remain stable in high temperatures.

This structural integrity at elevated temperatures means ROCKWOOL can maintain its insulation effectiveness and mechanical stability during a fire, preventing rapid heat transfer and structural damage.

Applications Where Fire Resistance Is Critical

Due to its high ignition temperature and non-combustibility, ROCKWOOL insulation finds extensive applications in industries requiring stringent fire safety measures. FUNAS' insulation products are used in:

• Petroleum and petrochemical plants


• Electric power generation facilities


• Metallurgy


• Polysilicon manufacturing


• Coal chemical industry


• Centralized air conditioning and HVAC systems


• Refrigerator refrigeration systems

These sectors benefit from ROCKWOOL’s ability to maintain integrity in fire scenarios, thereby keeping equipment and people safer.
