Fireproof And Durable Rock Wool Boards Withstanding High Temperatures Safely
Composed mainly of natural ores like basalt, with a melting point exceeding 1000℃, rock wool boards remain stable even in fire-induced high temperatures (600-800℃), without softening, dripping, or collapsing, thus maintaining their structural integrity and thermal insulation performance. Moreover, they release no toxic fumes when exposed to fire—only minimal harmless smoke—greatly reducing the risk of poisoning. These properties make rock wool boards ideal for high-fire-risk scenarios such as external wall insulation in high-rises, industrial firewalls, and fire-resistant bulkheads in ships, standing out as a safe and practical fire protection material.
Core Performance
The fire resistance of rock wool boards is one of their core advantages. Classified as non-combustible materials meeting international fire protection standards, our products neither burn nor support combustion under open flame or high temperatures, effectively blocking the spread of flames. Their fire resistance rating typically ranges from 1 to 4 hours; by adjusting thickness, they can meet the requirements of firewalls, fire barriers, and similar scenarios, buying precious time for evacuation and rescue efforts.
Multiple Applications
As for fire barriers, rock wool boards serve as core filling or isolation materials, finding extensive application in scenarios such as external wall insulation systems, curtain wall structures, pipe shafts, and cable trays. For example, in the external wall insulation layers of high-rise buildings, rock wool boards are installed as continuous vertical or horizontal fire barriers to block the spread path of flames among insulation materials; in pipe shafts and cable trenches, segmented isolation is formed by filling rock wool boards to prevent fire from spreading along pipelines.
Excellent Advantages
Compared with other materials, rock wool boards have significant advantages: Firstly, they feature high fire safety, fundamentally eliminating the risk of flame spread and meeting the rigid requirements for fire barriers specified in building fire codes such as GB 50016. Secondly, they have strong environmental adaptability, with resistance to high and low temperatures as well as aging, enabling them to function stably in both humid and dry environments, with a service life of over 20 years. Thirdly, they offer excellent construction compatibility, as they can be cut and processed according to specific scenarios and fit tightly with base layers like insulation layers and walls, reducing hidden dangers caused by construction gaps. Additionally, their inorganic material properties mean they do not release harmful substances due to aging or high temperatures, combining safety and environmental friendliness.
Comparison between Rock Wool Board and Other Materials in Firerpoofing
| Material | Fire Resistance Performance | Main Advantages | Application in Fire Barriers |
| Rock Wool Board | Class A non-combustible, fire resistance rating 1-4 hours, no toxic fumes at high temperatures, melting point ＞1000℃ | Combines fire resistance with basic thermal insulation, strong weather resistance (moisture and aging resistance), good construction compatibility | External wall insulation systems of high-rise buildings, curtain wall fire separations, vertical isolation of pipe shafts |
| Glass Wool | Class A non-combustible, fire resistance rating 0.5-2 hours, low smoke emission at high temperatures, melting point around 600℃ | Lightweight, better sound insulation than rock wool, slightly lower cost | Fire isolation in non-high-temperature areas (e.g., internal walls of multi-story buildings), ventilation duct interlayers |
| Fireproof Board (Calcium Silicate Board) | Class A non-combustible, fire resistance rating 2-6 hours, structurally stable at high temperatures | High strength, good flatness, can be directly used as facing | Main body of firewalls, cable tray separations |
| Intumescent Fire Retardant Coating | Class B1 flame-retardant, fire resistance rating 0.5-3 hours (related to coating thickness) | Can be directly applied to substrate surfaces, convenient for construction | Fire isolation of steel structures, wrapping of special-shaped components |
| Mineral Wool Board | Class A non-combustible, fire resistance rating 1-3 hours, relatively high thermal conductivity | Low price, meeting basic fire resistance requirements | Isolation belts in non-critical areas of ordinary buildings |
