Views:
China Overseas International Center in Beijing is a high‑end commercial complex with a modern facade curtain‑wall system. The project sets strict standards for fire resistance, vapour‑barrier moisture‑proof performance and surface flatness of insulation materials. After multi‑party comparison and screening, Aluminum‑foil Faced Curtain‑wall Rock Wool Board and rock wool composite panels supplied by Langfang Haochen Insulation Material Co., Ltd. are selected as curtain‑wall insulation materials to meet design requirements of different structural zones of the curtain wall.
I. Supply Information
Supplier: Langfang Haochen Insulation Material Co., Ltd.
Application Position: Insulation filling layer for building curtain wall
Product Details:
Aluminum‑foil Faced Curtain‑wall Rock Wool Board: 1200×600×50mm
Rock Wool Composite Panel: 1200×600×30mm
Total Supply Area: Approximately 23,000 ㎡
II. Advantages of Selected Products
Grade‑A Fire Resistance Meeting Fire Codes for Large Commercial Buildings
The rock wool core is made of basalt fibre, an A1‑grade non‑combustible material with stable fire‑resistant performance. It can effectively block flame spread and satisfy fire‑protection design requirements for curtain‑wall systems of large‑scale commercial office buildings, ensuring fire safety of densely‑occupied public buildings.
Aluminum‑foil Facing Provides Effective Vapour Barrier and Moisture‑proof Performance to Prevent Condensation inside Curtain Wall
Aluminum‑foil Faced Curtain‑wall Rock Wool Board delivers excellent vapour‑barrier performance, stopping water vapour from penetrating into rock wool core so as to avoid insulation failure caused by water absorption. It reduces risks of keel corrosion and internal condensation water seepage inside curtain walls, adapting to the climate with large temperature difference in Beijing.
Two Types of Panels Applied in Zones to Fit Diverse Curtain‑wall Structural Nodes
According to energy‑saving indicators and cavity thickness of different curtain‑wall positions, 50mm aluminum‑foil faced curtain‑wall rock wool board and 30mm rock wool composite panel are adopted respectively. They precisely match different structural thickness requirements and balance thermal insulation effect and on‑site installation conditions.
Standard Modular Size Suitable for Large‑area Curtain‑wall Construction
The unified 1200×600mm standard size matches conventional keel grids for curtain walls. Panels feature regular shape and convenient cutting, lowering material loss and supporting large‑batch simultaneous delivery and installation to guarantee construction progress.
Stable Panel Structure with Good Filling Fitness
Rock wool composite panels own flat surface and higher rigidity against loosening and damage. Aluminum‑foil faced rock wool boards have moderate flexibility for compact cavity filling to lessen thermal‑bridge effect and sustain overall thermal‑insulation performance of curtain walls.
III. Project Cooperation Highlights
✅ Two product types are produced separately, marked by category and delivered by zones for easy on‑site distribution and simplified site management;
✅ Product certificates and third‑party test reports are provided for each batch for efficient material admission inspection and supervision document review;
✅ Production is planned for the large‑volume demand of 23,000 ㎡, with stable batch‑by‑batch supply following construction schedule;
✅ The manufacturer’s technical team delivers construction reference solutions for curtain‑wall rock‑wool filling and cooperates with general contractor to tackle various node‑related construction challenges.
IV. Project Summary
The curtain‑wall insulation project of China Overseas International Center consumes about 23,000 ㎡ of Haochen aluminum‑foil faced curtain‑wall rock wool boards and rock wool composite panels. Zoned application of the two panels fully meets structural requirements for different curtain‑wall positions. All performance indicators comply with design and national specification standards, winning unanimous recognition from general contractor, supervision institute and project owner.
This project verifies that Haochen aluminum‑foil faced rock wool boards and rock wool composite panels are well‑suited for curtain‑wall insulation projects of high‑end office buildings and commercial complexes. Complete supporting solutions of multi‑specification insulation materials can be provided for large‑scale public building curtain‑wall projects.
