A1 Non Combustible Fireproof Rock Wool Board 30mm-150mm Thickness

Eco-friendly Fireproof Rock Wool Boards With Excellent Performance In Various Fields

The fire resistance of rock wool boards derives from their raw material properties and high-temperature stability. They are manufactured from natural rocks such as basalt and diabase, which are melted at temperatures exceeding 1500°C. As inorganic minerals, these rocks feature Class A non-combustible properties, fundamentally precluding the possibility of being ignited or supporting combustion. In contrast to Class B plastic insulation materials like EPS and XPS, rock wool boards do not burn or emit toxic fumes under high temperatures. Additionally, the melting point of rock wool is approximately 1000°C or higher, substantially surpassing the temperature of typical building fires (usually ranging from 600°C to 800°C). In the event of a fire, rock wool boards can maintain structural stability without softening or dripping, and they are capable of withstanding high temperatures for an extended period, thereby buying time for escape and fire suppression.

Advantages

Rock wool boards have notable advantages, widely preferred in diverse applications. Made from inorganic minerals like basalt, they are Class A non-combustible, resisting high temperatures without toxic fumes—unlike flammable plastics. They excel in thermal insulation too, with fibrous, porous structures ensuring low thermal conductivity, slowing heat transfer and boosting energy efficiency. Hydrophobic variants offer reliable moisture resistance (≤5% water absorption, ≤3% for high-quality ones), staying stable in humidity. They also provide sound insulation, while chemical stability and corrosion resistance ensure long life. Non-toxic and eco-friendly, they fit sustainable practices.

Applications

Rock wool boards find use in various additional scenarios. In construction, they’re applied to internal partition walls for fire and sound insulation, and as insulation in basement walls to resist moisture and temperature changes.​ Industrial furnaces and kilns utilize them for high-temperature insulation to improve energy efficiency. They’re also used in data centers to insulate server rooms, aiding temperature control.​ In transportation, they insulate train engine compartments and bus bodies. For cold storage facilities, they help maintain stable low temperatures. Historic building renovations often employ them for their non-intrusive insulation and fire safety.
