The Perfect Combination of Casement and Fixed Windows

In contemporary architectural design, window systems not only serve the basic functions of ventilation and daylighting but also play a crucial role in architectural aesthetics, energy efficiency, and living comfort. The ingenious combination of casement and fixed windows, through scientific profile design and glass configuration, can meet diverse requirements while enhancing overall visual appeal, making it an ideal choice for high-end residential and commercial buildings.

Superior Performance and Profile Selection for Casement Windows

Casement windows occupy a prominent position in the market due to their flexible opening mechanisms and excellent sealing performance. The core technology lies in the precision design of the profile system:

1、Profile Structure

• Thermal Break Aluminum Alloy Profiles: Featuring multi-chamber designs with high-strength nylon thermal barriers, effectively blocking heat transfer. Common profile widths include 60mm, 70mm, and 80mm series, with wider profiles offering better insulation.
• Reinforcement Design: Steel reinforcements integrated into the profiles significantly enhance wind resistance, making them particularly suitable for high-rise buildings.

2、Hardware System

High-end casement windows are equipped with multi-point locking hardware, ensuring even distribution of sealing pressure. Premium hardware undergoes tens of thousands of opening/closing tests to guarantee long-term durability.

3、Sealing System

Utilizing EPDM rubber seals to form a triple-sealing structure:

• Primary dust seal
• Secondary air seal
• Tertiary water seal
• This design achieves exceptional air tightness (reaching Grade 4 or above per national standards).

Technical Features and Innovative Applications of Fixed Windows

Fixed windows, with their minimalist aesthetics and outstanding performance metrics, have become essential elements of modern building facades:

1、Structural Design

• High-strength aluminum alloy frames with profile wall thickness exceeding 1.8mm ensure structural stability.
• Concealed drainage systems maintain aesthetics while effectively managing rainwater discharge.

2、Glass Configurations

• Double Glazing: Standard 5mm+12A+5mm configuration achieves a U-value of 2.8 W/(㎡·K).
• Triple Glazing: 5mm+12A+5mm+12A+5mm structure reduces U-values below 1.8.
• Low-Emissivity Coating: Effectively blocks infrared radiation for year-round thermal efficiency.

3、Large-Scale Applications

Through structural adhesives and mechanical fastening, single fixed window panels can span 3-4 square meters, providing unobstructed views.

System Solutions for Combined Applications

The scientific integration of casement and fixed windows leverages their respective advantages:

1、Balancing Ventilation and Views

• Modular "fixed + casement" combinations maintain expansive transparency while ensuring natural airflow.
• Common ratio: 70% fixed + 30% casement for optimal functionality.

2、Integrated Energy Efficiency

• Uniform air tightness achieved through pressure-equalized frame chambers.
• Thermal bridging minimized with integrated corner connectors.

Technological Advantages of Chinese Manufacturing

China's window manufacturing industry has developed a comprehensive supply chain and technical ecosystem:

1、Material Innovation
