Guanghua School of Management, Peking University is a top-tier teaching and research building for higher education and a key public university structure. The project has stringent requirements for building fire safety, energy-saving thermal insulation, acoustic performance and material durability. To meet the design requirements of the external thermal insulation composite system (ETICS), after multiple technical reviews and sample comparisons, high-density external wall rock wool boards from Langfang Haochen Insulation Materials Co., Ltd were selected as the primary thermal insulation material for the building’s external facade.
II. Supply Information
Supplier: Langfang Haochen Insulation Materials Co., Ltd
Application Area: Main layer of external wall thermal insulation
Product: External Wall Rock Wool Board
Specification: 140kg/m³, 1200×600×80mm
III. Advantages of the Selected Product
Class A1 Non-combustible, Compliant with Fire Codes for University Public Buildings
Made from basalt raw material, the rock wool board achieves Class A1 non-combustible performance. It will not easily melt under high temperatures and releases little toxic smoke, delivering excellent fire resistance. It meets mandatory fire safety standards for densely occupied university premises and greatly improves the fire safety rating of external building facades.
140kg/m³ High Density, Excellent Stability for External Thin-coat Render Systems
The board has adequate density and high transverse tensile strength, with outstanding slip and sag resistance. Compatible with ETICS thin-coat render construction, it resists hollowing and detachment over long service life and withstands day-night temperature swings and seasonal climate changes in Beijing.
Combined Thermal Insulation and Sound Absorption, Suitable for Teaching and Research Buildings
The porous fibre structure of rock wool delivers reliable thermal insulation and sound absorption. It effectively reduces building energy consumption and blocks external noise, creating a quiet and comfortable indoor environment for teaching, office work and academic exchanges.
Standard Modular Dimensions to Improve On-site Construction Efficiency
The 1200×600 standard boards feature smooth, even surfaces and simple cutting, reducing offcuts. They allow large-area continuous laying on external walls and shorten the construction schedule for facade works.
Water-repellent and Weather-resistant, Stable Long-term Performance
The product has good water repellency, moisture resistance and anti-ageing properties. It rarely deforms under damp conditions, ensuring stable long-term operation of the insulation system and lowering ongoing maintenance costs.
IV. Highlights of Project Cooperation
✅ As the original manufacturer, Haochen strictly controls board density, thickness and fibre uniformity. Certificates and third-party test reports are supplied for every batch to facilitate smooth site acceptance inspection;
✅ Production is scheduled in line with the construction programme. Goods are delivered in batches on time to ensure the steady progress of external insulation works;
✅ Our technical team provides construction support and assists contractors with critical details including board layout and joint treatment;
✅ A full set of documentation is provided to support project completion acceptance and filing.
V. Project Summary
The Guanghua School of Management project extensively adopted Haochen 140kg/m³ high-density external wall rock wool boards. Balancing fire safety, energy saving and sound insulation, all performance parameters satisfy design and regulatory requirements and gained recognition from the main contractor, supervision team and project owner.
This project fully demonstrates that Haochen high-density rock wool boards are widely applicable for facade insulation works on high-standard public buildings such as university teaching blocks, research offices and commercial developments, serving as the preferred thermal and fire insulation material for densely occupied public buildings.
