Environmentally Friendly And Safe Rock Wool Boards Suitable For Various Fields
The safety and non-toxicity of rock wool boards are among their core advantages distinguishing them from many chemical synthetic building materials. This characteristic runs through the entire life cycle of the material itself, production and processing, and long-term use, which can be elaborated in detail from the following dimensions.
Authoritative Certification and Standard Endorsement
The safety and non-toxicity of rock wool boards have passed a number of authoritative standard certifications at home and abroad. Domestically, their combustion performance meets the Class A non-combustible standard in Classification for Burning Behavior of Building Materials and Products (GB 8624-2012), and at the same time complies with the "not detected" level in Limit of Formaldehyde Emission of Wood-based Panels and Their Products for Indoor Decoration and Furnishing Materials (GB 18580-2017), that is, the formaldehyde emission is less than 0.1mg/m³, which is far lower than the national standard limit.
In the international market, rock wool boards have also obtained EU CE certification, US UL certification, etc. Among them, the EU's Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation clearly classifies rock wool as a "harmless substance" that does not require toxic substance registration; the US Environmental Protection Agency (EPA) also identifies rock wool as a "low-risk material for humans and the environment" and allows unrestricted use in residential and commercial buildings. These authoritative certifications provide a solid guarantee for the safety and non-toxicity of rock wool boards from the legal and standard levels.
Disposal and Recycling Outstanding Environmental Safety
The environmental safety of rock wool boards is also reflected in their waste disposal stage. Due to their main component being inorganic minerals, waste rock wool boards can be directly landfilled without being difficult to degrade in the natural environment like organic materials such as plastics and rubber, nor will they seep into soil or groundwater to cause chemical pollution. At the same time, waste rock wool boards can be recycled through processes such as crushing and remelting to make new rock wool products or building aggregates, realizing resource recycling, reducing solid waste pollution, and conforming to the development concept of "green building materials".
In summary, the safety and non-toxicity of rock wool boards stem from their natural inorganic material nature, physical production process, and environment-friendly characteristics throughout the entire process of use, construction, and disposal. Coupled with strict certification by authoritative standards, they have become high-quality building materials with insulation, fire resistance, and safety performance, fully meeting the core requirements of building engineering for non-toxic and safe materials.
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 |
