Product Specifications
The rigid rockwool board is engineered with a high-density fiber matrix (typically 80kg/m³ to 200kg/m³) to withstand mechanical loads without deformation. It features an acidity coefficient above 1.6, ensuring long-term chemical stability and resistance to aging. The material maintains a thermal conductivity typically around 0.040 W/(m·K) and possesses a hydrophobicity rate exceeding 98%, effectively blocking moisture infiltration. Capable of enduring temperatures over 1000°C, it acts as a critical firestop preventing flame spread through wall or roof assemblies.
Application Areas
This material is utilized in flat roof insulation and floating floor systems where the insulation layer must support weight or foot traffic. It serves as the core material for External Thermal Insulation Composite Systems (ETICS) and curtain wall facades. In industrial settings, it is applied to high-temperature tank walls and large vessels requiring rigid support, as well as serving as the core for fire doors and sandwich panels.
Certifications
Manufacturing adheres to ISO9001 quality management protocols to ensure consistency. The products carry CE and SGS certifications, confirming compliance with international standards for compressive strength, fire safety, and thermal performance to facilitate export clearance.
Factory
Our facility operates two standardized lines equipped with an automated batching system, increasing production efficiency by 60% to meet bulk delivery schedules. We manufacture the rigid rockwool board with precise density control to ensure uniform compressive strength across all batches. The production process includes real-time monitoring and supports custom cutting and packaging, with printed batch numbers provided for supply chain traceability.






FAQ
Q1: What compressive strength ratings can you achieve?
We produce boards with compressive strength typically ranging from 40kPa to 80kPa, depending on the density (e.g., 140kg/m³ to 180kg/m³). We can tailor the density to meet the specific load-bearing requirements of your roofing or flooring project.
Q2: Is this board compatible with external rendering systems?
Yes, the high surface strength and dimensional stability of our rigid boards make them suitable for direct application in rendering systems (ETICS). We can provide specific surface treatments or tolerance specifications to ensure compatibility with adhesives and base coats.
Q3: How do you optimize loading for high-density rigid boards?
Since rigid boards are heavier, we calculate the optimal pallet height and weight distribution to maximize container space without exceeding weight limits. We use reinforced pallets and corner protection to prevent edge damage during forklift handling and ocean transport.
