This technical guide provides a standardized interpretation of double skin curtain wall, a high-performance glass facade system manufactured by Guangdong AoBang Curtain Wall Technology Co., Ltd. As a supplier with over 10 years of industry experience in overseas curtain wall projects, we have delivered solutions for markets in Central Asia, Russia, and Southeast Asia . Double skin curtain wall is designed for commercial real estate developers, EPC contractors, and public infrastructure project owners, addressing core pain points including high building energy consumption, surface condensation, and excessive light pollution . Our products follow international standards for facade design and testing, with core innovations in thermal insulation and modular assembly. The system has been validated in applications including high-rise office buildings, commercial complexes, hotels, and hospital facilities, supported by a full quality control process that ensures a 100% project pass rate .
Technical Definition
Double skin curtain wall is a peripheral building enclosure system consisting of two layers of glass panels separated by a ventilated air cavity, fixed to the main building structure via aluminum alloy keels or steel support systems. It does not bear main building loads, and only withstands self-weight, wind load, seismic action, and temperature deformation . As a core solution in the building facade industry, it is widely adopted for projects requiring high energy efficiency and modern visual appearance.
Main Product Series
To meet diverse project requirements, our double skin curtain wall covers two core series, with custom solutions available for special working conditions:
1. Standard Ventilation Series: Optimized for commercial complexes and office buildings, featuring natural ventilation in the air cavity to reduce cooling loads .
2. High Insulation Custom Series: Designed for cold climate regions, with Low-E coated hollow glass to minimize heat transfer in winter.
Core Design Philosophy
Our double skin curtain wall is developed with the core design principles of high reliability, easy maintenance, and long service life. We follow full lifecycle reliability design standards to adapt to harsh outdoor working conditions, providing stable, cost-effective solutions for global clients .
Working Principle
The core working principle of double skin curtain wall relies on the thermal buffer effect of the middle ventilated air cavity. The complete load and energy transfer chain is as follows: external environmental loads are first absorbed by the outer glass panel, then the air cavity regulates temperature and pressure before the inner glass panel transfers remaining loads to the main building structure via keels and connectors .
Core System Architecture
The system is divided into three modular components for improved performance and adaptability:
1. Outer Glass Panel Module: Made of tempered Low-E hollow glass, reducing solar heat gain and preventing surface condensation .
2. Ventilated Air Cavity Module: Equipped with adjustable ventilation openings to enable natural or mechanical ventilation, reducing cooling energy consumption by up to 30% compared to single-layer curtain walls.
3. Inner Seal System: Composed of silicone structural sealant and weather-resistant sealant, ensuring air tightness and water tightness for the building enclosure.
