General Contractor: China Construction First Bureau
Project Name: Tsinghua University Tongzhou Financial Development and Talent Training Base
Project Profile: Key university construction project, a large public building integrating scientific research, teaching, talent training and commercial office with facade curtain wall system. The project sets high standards for fire resistance, dimensional accuracy and construction adaptability of insulation materials. After multi-party technical comparison and screening, curtain wall filling insulation material adopts curtain wall rock wool board supplied by Langfang Haochen Insulation Material Co., Ltd.
I. Supply Information
Supplier: Langfang Haochen Insulation Material Co., Ltd.
Application Position: Insulation filling layer for building curtain wall
Product: Curtain wall filling rock wool board
Specification: 100kg/m³, 1200×400×50mm
Total Usage Area: Approximately 15,000 ㎡
II. Advantages of Selected Products
Class A Non-combustible Rock Wool Meeting Fire Standards for University Public Buildings
The rock wool board is made of basalt fibre and reaches A1 non-combustible grade with stable fire resistance. It can effectively block flame spread and comply with curtain wall fire protection design codes for crowded university complex buildings to strengthen building fire safety.
Custom Size Matches Curtain Wall Keel Grid to Reduce Material Waste
Custom size of 1200×400mm precisely matches the keel grid of this project’s curtain wall. Mass secondary cutting is not required, reducing offcuts, improving material utilisation and saving project costs.
100kg/m³ Special Density for Curtain Wall, Convenient Filling Construction
The board features evenly distributed fibres and good flexibility for easy filling and laying inside curtain wall cavities. It fits gaps of curtain wall structure, reduces thermal bridge effect, guarantees continuous thermal insulation of curtain wall system and stably achieves energy-saving design indicators.
Hydrophobic and Weather-resistant, Adaptable to the Climate of Beijing
The board has good hydrophobic performance and hardly absorbs moisture. Its thermal insulation performance will not decline due to water vapour intrusion during long-term service. It resists seasonal temperature changes and rain and snow erosion to extend the service life of curtain wall insulation system.
High Flatness for Large-area Standardised Construction
Smooth board surface and low damage risk during transportation, suitable for large-scale simultaneous construction. It satisfies the on-site standard management requirements of China Construction First Bureau and ensures efficient curtain wall insulation works.
III. Project Cooperation Highlights
✅ Special production scheduling according to custom specifications to guarantee stable continuous supply of bulk boards;
✅ Product certificates and third-party test reports provided for each batch for efficient material inspection and supervision document review;
✅ Batch delivery arranged according to construction progress with well-planned logistics to ensure seamless supply on site;
✅ On-going technical support from manufacturer, providing construction reference for curtain wall rock wool filling and cooperating with general contractor to implement construction process requirements.
IV. Project Summary
Around 15,000 ㎡ of Haochen curtain wall filling rock wool boards were used for the curtain wall project of Tsinghua University Tongzhou Financial Development and Talent Training Base. Custom-sized boards perfectly fit the curtain wall keel structure of this project. All product performance indicators meet design and national specification requirements, and the construction effect has been highly recognised by China Construction First Bureau and supervision institute.
This project fully verifies that Haochen can customise non-standard size rock wool boards according to curtain wall engineering demands. The products are widely applied to curtain wall filling insulation works for university research bases, sci-tech parks and large office complexes. Haochen is a reliable insulation material supplier for large key public construction projects.
