The Thermal Insulation Magnesium Rockwool Sandwich Panel is a high-performance building material engineered for B-end industrial and construction projects with strict fireproof and airtight requirements. Crafted with a pre-painted galvanized steel sheet surface, a 5mm high-density glass magnesium core, and premium rock wool insulation layer, this panel is formed through precision pressing and high-temperature heating processes, resulting in a high airtight magnesium rockwool panel with exceptional structural stability and fire resistance. As a Grade A fireproof magnesium rockwool panel, it outperforms conventional building panels in extreme working conditions, delivering comprehensive protection for industrial buildings, clean rooms, and high-risk fire areas. Its integrated production process ensures uniform material bonding, eliminating common issues like delamination and deformation, making it a reliable core material for B-end clients pursuing safety, durability, and energy efficiency in construction projects.
Grade A Fireproof & Non-inflammable: Certified as Lever A fireproof (the highest fire rating for building panels), it is non-inflammable and can withstand high temperatures for extended periods, effectively preventing fire spread and meeting national fire code standards for high-risk industrial areas.
High Airtightness & Waterproofing: The high-temperature pressing process creates a seamless structure with excellent airtight and waterproof performance, avoiding air leakage and water seepage, and maintaining thermal insulation efficiency in humid or outdoor environments.
Eco-friendly & Stable Performance: Tasteless, non-toxic, and free of harmful substances, it complies with green building standards. It also features ice-free, stale-proofing, crack-proof, and non-deformation properties, adapting to extreme temperature changes without performance degradation.
High-strength & Lightweight: The composite structure of glass magnesium core and rock wool balances high mechanical strength and light weight, reducing building load while ensuring structural stability, suitable for both load-bearing and non-load-bearing building enclosures.

Conduct Pre-installation Preparation by inspecting panel specifications for consistency with project design and ensuring Tongued and Grooved connectors are intact and free of deformation. Store panels in a dry, ventilated area, elevated 10cm above the ground to avoid moisture absorption. Perform Base Layer Treatment by cleaning the steel or concrete base to remove oil, dust, and rust, and ensure flatness (deviation ≤5mm/2m) and verticality for stable installation. Carry out On-site Assembly with a bottom-to-top installation sequence and Tongued and Grooved seamless splicing, and use special waterproof gaskets and self-tapping screws for fixation (nail spacing ≤300mm, encrypted to ≤200mm at corners). Complete Sealing & Finishing by filling splicing seams and screw holes with fireproof sealant to enhance airtightness and fire resistance, and install dedicated corner trims for wall corners to ensure structural integrity and aesthetic finish. Conduct real-time Quality Inspection during installation to check panel flatness and verticality, and ensure no gaps at splices and sealant is evenly applied without bubbles or cracks.
This panel is widely used in B-end projects with high fireproof and thermal insulation demands, including: high fire rate industrial workshops (chemical, metallurgy, power), clean rooms for electronics and pharmaceuticals, fire-resistant enclosures for warehouses and logistics centers, military construction projects, and public buildings (hospitals, shopping malls) with strict fire code requirements. It is also an ideal material for HVAC clean room systems, providing integrated thermal insulation and fire protection for airtight building environments.
We offer tailored customization services for B-end bulk projects to meet diverse project requirements with targeted solutions. Realize Dimension Fine-tuning by customizing panel length within the range of standard width (950mm/1150mm) for on-site construction convenience. Provide Surface Customization to tailor pre-painted galvanized steel sheet colors and coating thickness to match project aesthetic and anti-corrosion requirements. Implement Core Material Optimization by adjusting rock wool insulation density for enhanced thermal insulation performance in extreme temperature environments. Offer Fireproof Reinforcement with customized fireproof coating treatment for panels applied in ultra-high fire risk areas (e.g., chemical plants). Provide professional Bulk Project Support including technical drawings and on-site installation guidance for large-scale construction projects.
With pre-painted galvanized steel surface and waterproof sealant treatment, the panel has a service life of 15+ years in outdoor environments; regular maintenance can extend it to over 20 years, meeting the long-term use needs of industrial projects.
Yes. It features ice-free and non-deformation properties, and the rock wool insulation layer maintains excellent thermal insulation performance at low temperatures, making it suitable for cold storage, northern outdoor construction, and other low-temperature environments.
Absolutely. Its lightweight and Tongued and Grooved quick-splicing design is perfectly adapted to modular building construction, significantly shortening on-site construction time and improving project efficiency for B-end modular building clients.
