External Wall Rock Wool Board for University Public Building
Published:
Views:
Guanghua School of Management, Peking University is a top-tier higher education teaching and research building and a key public university building. The project imposes stringent requirements on building fire safety, energy-saving thermal insulation, acoustic performance and material durability. To meet the design specifications of the external thermal insulation composite system (ETICS), after multiple technical assessments and sample comparisons, high-density external wall rock wool boards supplied by Langfang Haochen Insulation Materials Co., Ltd were selected as the main thermal insulation material for the building 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 Selected Product
A1 Non-combustible, compliant with fire codes for university public buildings
Manufactured from basalt raw material, the rock wool board achieves Class A1 non-combustible performance. It resists melting under high temperatures and releases minimal toxic smoke, delivering outstanding fire resistance. It satisfies mandatory fire safety requirements for densely occupied university premises and greatly upgrades the fire protection standard of building external facades.
140kg/m³ High Density, superior stability for external thin-coat render systems
The board features sufficient density and high transverse tensile strength, with excellent slip and sag resistance. Fully compatible with ETICS thin-coat render construction, it resists hollowing and detachment over long service life, adapting to day-night temperature fluctuations and seasonal climate variations in Beijing.
Integrated thermal insulation and sound absorption, ideal for teaching & research buildings
The porous fibre structure of rock wool provides excellent thermal insulation and sound absorption. It effectively cuts 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 boost on-site construction efficiency
The 1200×600 standard-sized boards have smooth, regular surfaces and can be cut easily, reducing offcuts. They facilitate large-area continuous laying on external walls and shorten the construction period of facade works.
Water-repellent & weather-resistant, stable long-term performance
The product possesses reliable water repellency, moisture resistance and anti-ageing properties. It is less prone to deformation from dampness, ensuring long-term stable operation of the insulation system and lowering subsequent maintenance expenditure.
IV. Key Highlights of Project Cooperation
✅ As the original manufacturer, Haochen strictly controls board density, thickness and fibre uniformity. Certificates and third-party test reports are provided for every batch to pass site acceptance inspection smoothly;
✅ Production is scheduled according to the construction programme of the project. Goods are delivered in batches on time to guarantee the orderly progress of external insulation works;
✅ Our technical team offers on-site construction support and assists contractors in managing critical procedures including board layout and joint treatment;
✅ Complete document packages are supplied to support project completion acceptance and file archiving.
V. Project Summary
Haochen 140kg/m³ high-density external wall rock wool boards were widely applied to the external facade of the Guanghua School of Management project. Balancing fire safety, energy conservation and sound insulation, all performance indicators meet design and regulatory standards, winning recognition from the main contractor, supervision unit and project owner.
This project fully demonstrates that Haochen high-density rock wool boards are widely suitable for external insulation projects of high-standard public buildings such as university teaching buildings, research office blocks and commercial buildings. It is the preferred insulation and fire protection material for densely occupied public constructions.
