Rock wool panels, with their Class A non-combustibility, high-temperature stability, and durable fire performance, are widely applied in critical building safety scenarios. For exterior wall insulation— a major fire risk point in high-rises and commercial complexes—they act as the core material in external, internal, and sandwich insulation systems. Combined with rendering mortar and alkali-resistant glass fiber mesh to form a composite system, their non-combustibility prevents "chain-type" fires from insulation layer ignition, blocks flames from entering buildings through windows or gaps, and avoids becoming a fire carrier.
What are their specific use cases categorized by building components and functional requirements?
To meet building fire codes, rock wool panels construct fire-resistant internal partitions and divide fire zones. With thicknesses from 50mm to 150mm, they enable partitions to achieve a 1–4 hour fire resistance limit (adjustable by rating). Typically installed between mall atriums and shops, office areas and server rooms, or hotel guest floors and corridors, they restrict fires to specific areas, prevent rapid spread, and create independent evacuation spaces.
For roofs, which need protection against external sources like fireworks and equipment malfunctions such as AC unit fires, rock wool panels are laid directly on structural layers, covered with waterproof membranes and protective panels to form an integrated system with insulation, waterproofing, and fire resistance. They block roof fires from spreading inward and maintain structural integrity under high temperatures to prevent collapse, rain leakage, or fire intrusion.
In pipeline and equipment insulation, rock wool panels (often cylindrical "shells" for pipes) offer targeted protection. For fire pipelines, they insulate against freezing while shielding pipes from high-temperature damage during fires, ensuring unobstructed water flow for suppression. Wrapped around air conditioning ducts, they create fire-resistant ductwork to stop flame spread via ventilation. For industrial equipment like boilers, heat exchangers, and furnaces, they resist high-temperature deformation and reduce overheating risks.
In high-safety venues with strict demands, their non-toxic, stable performance provides enhanced protection. In data centers, they are installed in server room walls and ceilings to insulate high temperatures, protect precision equipment, and avoid toxic gases harming staff. Hospitals use them in operating room partitions, ward walls, and equipment rooms to minimize risks. For schools and nursing homes, they are applied in classroom partitions, dorm walls, and corridor ceilings as reliable fire barriers, meeting standards for vulnerable populations.
| Building Materials | Fire Performance Class | Fire Resistance Rating | Characteristics When Burning | Applicable Scenarios |
|---|---|---|---|---|
| Rock Wool Board | Class A1 (Non-combustible) | 1-4 hours | Does not burn, maintains structural stability | Wall insulation, fire barriers |
| Expanded Polystyrene (EPS) | Class B2 (Combustible) | 0.1-0.3 hours | Releases toxic fumes, fast fire spread | Low-rise buildings (with fire protection) |
| Polyurethane Foam (PU) | Class B3 (Flammable) | <0.1 hours | Highly flammable, releases toxic gases | Restricted non-exposed uses |
| Glass Wool Board | Class A1 (Non-combustible) | 0.5-2 hours | Stable at high temperatures | Duct insulation, partition walls |
