- Product Overview
Our rock wool sandwich panel is a high-performance Class A non-combustible insulation board widely used for exterior wall insulation, building envelope systems and industrial thermal insulation projects. Made of natural basalt and mineral wool raw materials, this fireproof rock wool panel features low thermal conductivity of 0.04 W/(m·K), excellent sound absorption, strong hydrophobic performance and high temperature resistance above 1000°C. As a professional OEM insulation board manufacturer, we provide customized density 60–180kg/m³ and custom sizes from 30mm to 150mm thickness to meet diverse construction and industrial requirements.
Different from ordinary insulation materials, our rock wool sandwich panel achieves perfect integration of fire safety, energy saving, sound insulation and moisture resistance, making it the most reliable passive fire protection and thermal insulation solution for modern buildings, factories, power plants, metallurgy, shipbuilding and chemical industrial projects.
- Class A Fireproof & High Temperature Resistant Performance (Core Selling Point)
This rock wool sandwich panel is certified with GB 8624 Class A non-combustible grade, completely non-flammable and smoke-free in high-temperature fire scenarios. The rock wool core can continuously resist extreme temperature over 1000°C without melting, dripping or releasing toxic smoke, greatly improving building fire safety grade and avoiding fire spread risks.
For exterior wall insulation systems, Class A fireproof rock wool panels are the mandatory safe material for high-rise buildings, public buildings and industrial plants. It provides stable passive fire protection all year round and effectively reduces building fire hazards, which is why global architects, contractors and engineering companies prefer our non-combustible rock wool insulation boards.
- Ultra-Low Thermal Conductivity 0.04 W/(m·K), High Energy Saving Efficiency
The open porous fiber structure of the rock wool core effectively locks static air, achieving an ultra-low thermal conductivity of 0.04 W/(m·K) at room temperature. This excellent thermal insulation performance greatly reduces indoor and outdoor heat exchange, cutting building air conditioning and heating energy consumption by up to 30% annually.
Whether for residential exterior wall insulation, commercial building thermal preservation or industrial equipment heat insulation, our rock wool sandwich panel delivers stable energy-saving effects, lowers operational costs and improves overall building thermal performance.
- Professional Sound Absorption & Noise Reduction Effect
The multi-layer porous fiber structure of the rock wool board can effectively absorb and weaken various frequency noise waves, providing outstanding acoustic insulation performance. It perfectly solves noise pollution problems for factories, workshops, urban buildings, equipment rooms and public spaces, creating quiet and comfortable working and living environments.
- Hydrophobic & Breathable, Long Service Life
Our rock wool insulation panel adopts professional hydrophobic treatment technology, with strong water-repellent performance on the surface. Meanwhile, the breathable fiber structure allows internal moisture to evaporate freely, avoiding water accumulation, mold growth, corrosion and structural damage. It maintains stable physical and chemical properties for decades without deformation, aging or rotting.
High-temperature curing processing further enhances fiber strength, dimensional stability and structural durability, ensuring long-term reliable performance in humid, high-temperature and harsh industrial environments.
