Rock Wool Boards For A Wide Range Of Applications With Excellent Performance
The safety and non-toxicity of rock wool boards are among their core advantages distinguishing them from many chemical materials. This characteristic runs through the entire life cycle of the material itself, production and processing, and long-term use. Rock wool boards are made from raw materials such as basalt and diabase through high-temperature melting. With multiple advantages, they play an important role in various fields.
Remarkable Benefits
First, they have strong fire resistance, capable of withstanding temperatures above 800°C, which can effectively block the spread of fire and ensure safety; second, they exhibit excellent thermal insulation performance, reducing heat loss or isolating external high temperatures to maintain a stable ambient temperature; third, they possess good sound insulation properties, absorbing noise and reducing environmental noise interference; fourth, they are moisture-resistant and corrosion-resistant, capable of resisting water penetration and material corrosion, thereby extending the service life of themselves and related facilities; fifth, they are non-toxic and environmentally friendly, without releasing harmful substances, posing no harm to organisms and the environment, and meeting safety standards.
Functional Applications
In terms of functional applications, rock wool boards have a wide range of uses. In the industrial field, they serve as thermal insulation materials for pipelines and equipment, reducing heat loss and ensuring the stable operation of equipment. In the construction field, they are used as thermal insulation layers for walls and roofs to contribute to building energy efficiency, and can also be used as core materials for fire doors to improve the fire resistance rating of buildings. In the transportation field, they are applied in the battery packs of new energy vehicles for thermal insulation and fire protection, and in the engine compartments and undercarriages of traditional fuel vehicles for sound and thermal insulation; ships, high-speed trains, and aircraft also rely on them to achieve fire resistance, thermal insulation, and noise reduction. In the agricultural field, they help greenhouses maintain a constant temperature to promote crop growth, and can be processed into seedling substrates to improve the survival rate of seedlings; they are also used in livestock houses for thermal insulation and sound absorption, reducing stress in livestock and improving breeding efficiency. In the aquaculture field, they are used in overwintering greenhouses in northern regions to prevent water from freezing, ensuring the safe overwintering of aquatic products; at the same time, they can be used as sound insulation and moisture-proof layers for facilities, maintaining a stable aquaculture environment and extending the service life of facilities.
Comparison of Several Construction Marerials
| Comparison Items | Rock Wool Board | Polystyrene Board (EPS/XPS) | Polyurethane Board (PU) | Glass Wool Board | Aerated Concrete Block |
| Combustion Performance | Class A non-combustible (highest grade) | Class B1-B2 (flame-retardant-combustible) | Class B1 (flame-retardant, toxic fumes released at high temperatures) | Class A non-combustible | Class A non-combustible |
| Thermal Conductivity (W/(m·K)) | 0.036-0.048 | 0.030-0.040 (EPS); 0.028-0.032 (XPS) | 0.022-0.028 | 0.035-0.045 | 0.16-0.28 |
| Insulation Performance | Good | Excellent (XPS better than EPS) | Superior (best insulation effect) | Good | Average |
| Sound Insulation Performance | Excellent (fiber structure blocks air and solid sound transmission) | Average (low density, weak in blocking low-frequency noise) | Good (closed-cell structure, slightly better than polystyrene) | Good (fiber structure, mainly sound absorption) | Good (porous structure, moderate sound insulation) |
| Mechanical Strength | Compressive strength ≥40kPa, good toughness | EPS compressive strength ≥100kPa; XPS ≥200kPa | Compressive strength ≥200kPa, high hardness | Low compressive strength (≤30kPa), easy to break | Compressive strength ≥3.5MPa, high strength |
| Temperature Resistance Range | -268℃ to 650℃ (high-temperature resistant) | -50℃ to 70℃ (easy to deform at high temperatures) | -50℃ to 120℃ (easy to age beyond this range) | -120℃ to 400℃ | -50℃ to 600℃ (high-temperature resistant) |
| Weather Resistance | Moisture-resistant, anti-aging, adaptable to multiple climates | EPS absorbs water easily; XPS shrinks at high temperatures | Vulnerable to UV rays (needs protective layer), average water resistance | Poor water resistance (insulation drops when wet) | Moisture-resistant, good frost resistance |
| Environmental Friendliness | Made from natural rocks, formaldehyde-free, recyclable | Organic material, some contain flame retardants, hard to degrade | Contains isocyanates, emission control required during production | Glass fibers may irritate skin, average recyclability | Inorganic material, non-toxic, recyclable |
| Key Advantages | 1. Top-level fire resistance, high safety 2. Integrates insulation, soundproofing, and weather resistance 3. Adapts to harsh environments (high temperature, humidity, etc.) | 1. High insulation efficiency, low cost 2. Lightweight for construction, suitable for low-risk scenarios | 1. Optimal insulation performance, significant energy-saving effect 2. High strength, good integrity | 1. Excellent sound absorption, suitable for acoustic scenarios 2. Low cost | 1. Integrates load-bearing and insulation 2. Durable, same lifespan as buildings |
| Typical Applications | External wall insulation, fire barriers, industrial pipeline insulation | Internal building insulation, low-temperature storage, packaging cushioning | High-end building insulation, cold storage insulation, pipeline insulation | Concert halls, machine room soundproofing, ceiling filling | Wall masonry, self-insulating buildings |
