Fire-Resistant Rock Wool : Optimal Insulation For Exterior Wall Systems

Rock wool panels offer multiple key benefits when used for exterior wall insulation, combining fire safety, thermal performance, and practical adaptability. Our eco-friendly fireproof rock wool boards are manufactured from natural basalt and diabase rocks melted at temperatures exceeding 1500°C. These inorganic mineral boards feature Class A non-combustible properties, fundamentally eliminating ignition risks. Here are some benefits and applications of our products.

Unmatched Fire Safety Protection

As Class A non-combustible materials, they eliminate the risk of ignition and combustion—unlike organic insulation that burns, drips, or releases toxins. This prevents "chain-type" fires triggered by exterior wall insulation, blocks flames from penetrating buildings through windows or wall gaps, and avoids the insulation itself becoming a fire carrier, which is critical for high-rises and commercial complexes.​

Excellent Thermal Insulation with Durability

Their low thermal conductivity (0.036-0.048W/(m·K)) effectively reduces heat transfer between indoors and outdoors, cutting energy consumption for heating and cooling. Unlike organic materials prone to aging, shrinking, or decomposing, rock wool’s inorganic structure resists moisture, mildew, and weathering, maintaining stable insulation performance over the building’s lifespan without frequent replacement.​

Compatibility with Exterior Wall Systems

Rock wool panels integrate seamlessly with common exterior wall configurations—external insulation, internal insulation, or sandwich insulation. When paired with rendering mortar and alkali-resistant glass fiber mesh, they form a robust composite system that adheres well to wall substrates, resists cracking, and enhances the overall structural stability of the exterior envelope.​

Synergistic Safety in Fire Emergencies

Beyond non-combustibility, rock wool retains structural integrity at high temperatures (withstanding over 600℃), preventing insulation layer collapse during fires. This acts as a thermal barrier, slowing heat penetration to protect internal wall structures (e.g., steel, concrete) from damage and buying precious time for personnel evacuation.

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
