Qingdao China-Europe Industrial Park

Project Overview

The Qingdao China-Europe Industrial Park is a key international cooperation zone developed by the city of Qingdao. The overall masterplan focuses on modern industrial clusters, corporate headquarters, and R&D innovation centers. Multiple buildings within the park adopt large-area glass curtain walls to enhance natural lighting, energy efficiency, and contemporary architectural aesthetics.

For this project, Weihua Glass supplied a total of 18,000 m² of 6mm Low-E (CSG) + 12A + 6mm double-tempered insulated glass, fully covering the façade requirements of the park’s R&D center, administration office buildings, and supporting commercial areas.

Product Specifications & Glass Configuration

Configuration:
6mm Low-E (CSG) + 12A + 6mm double-tempered insulated glass

Total Supply:
18,000 m²

Key Glass Features

• High-performance Low-E coating for excellent energy-saving performance

• Double-tempered structure (6T + 6T) significantly enhances safety and wind-load resistance

• Insulated cavity improves acoustic performance and thermal insulation of the façade

Typical Performance Values

• Visible Light Transmittance (VLT): ≈ 55–65%

• U-value: ≤ 1.8 W/m²·K

• Solar Heat Gain Coefficient (SHGC): ≤ 0.40

Design & Fabrication Highlights

1. Large Panel Sizes & Mixed Dimensions

Approximately 30% of the units were large-format glass panels
(width ≥ 1.8 m, height ≥ 3 m), requiring exceptional flatness and consistent tempering quality. Dedicated production lines and dual tempering furnaces ensured stable stress distribution and uniform break patterns.

2. Low-E Coating Orientation & Surface Protection

During IGU assembly, the Low-E coating surface was strictly controlled to face the correct interior position. All membrane-protection procedures followed Level I national standards for anti-scratch and anti-contamination performance.

3. Sealing System

• Primary seal: Hot-melt butyl

• Secondary seal: Polysulfide sealant (optimized for long-term curtain wall durability)

This system ensures low dew point and long-term air-tightness of the insulated units.

4. On-site Measurement & Engineering Coordination

Our engineering team participated in multiple rounds of façade design refinement and collaborated closely with the curtain wall contractor. Accurate dimension verification enabled modularized mass production, greatly reducing rework and on-site delays.

Quality Control System

To guarantee consistent quality across the 18,000 m² supply, a dedicated QC protocol was implemented throughout the project:

Testing Included

• Insulated glass dew point testing

• Tempered glass fragmentation test

• Impact and wind-load simulation

• Low-E coating adhesion test

• Full-surface visual inspection

• Batch-by-batch sampling checks

Large-format units also underwent stress-wave analysis to ensure uniform internal stress distribution.

Project Outcome & Performance

Upon completion, the glass façade delivers a modern, clean, and high-tech architectural appearance. Field measurements and energy modeling indicate:

• Indoor temperature fluctuation reduced by 20–28%

• Estimated energy savings of 15–25%

• Significant improvement in acoustic insulation, resulting in a quieter, more efficient office environment

• Uniform façade color, high transparency, and excellent flatness enhanced the overall international and technological image of the industrial park
