Product Description
Rock Wool Boards With Excellent Fire Resistance For Safe Building Applications
In the construction industry, rock wool boards stand out as crucial safety materials due to their excellent fire resistance. Their benefits span the entire lifecycle of buildings, playing an irreplaceable role from daily use to emergency protection.
Safeguarding Lives and Extending Evacuation Time
Rock wool boards are non-combustible, typically meeting the A1 class standard in GB 8624-2012 Classification for Burning Behavior of Building Materials and Products. During a fire, they do not burn, emit open flames, or release toxic fumes—major causes of casualties in building fires. By blocking fire spread and maintaining structural stability, rock wool boards create clear, safe evacuation routes, extending the critical escape time by 30-60 minutes and significantly improving survival rates.
Reducing Property Loss and Repair Costs
Building fires cause losses not only to furniture and equipment but also to the building structure itself. Traditional flammable insulation materials accelerate fire spread to walls and roofs, damaging load-bearing components. In contrast, rock wool boards curb fire spread and retain structural strength under high temperatures, minimizing single-household losses and overall repair expenses.
Meeting Fire Codes and Avoiding Compliance Risks
With stricter building safety standards, countries have rigid requirements for material fire resistance. As a natural non-combustible material, rock wool boards easily meet these requirements, helping developers and contractors avoid project halts, failed inspections, and penalties due to non-compliant materials.
Enhancing Overall Building Fire Rating and Long-Term Safety
Rock wool boards are versatile: used in exterior wall/roof insulation, firewalls, partition walls, and cable shaft sealing. By applying rock wool boards in key areas, buildings form a "three-dimensional" fire protection system, maintaining high safety stability over decades.
Balancing Fire Protection and Functionality
Rock wool boards integrate insulation, sound absorption, and moisture resistance, suiting diverse scenarios. In cold regions, they reduce winter heat loss while ensuring safety. In hospitals and laboratories, their non-combustible and non-toxic properties meet fire requirements without harming indoor air quality.
Comparison of Construction Materials
| 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 |
