The Circlip ventilated facade support system is an energy-efficient building exterior wall technology that combines a double-layer facade structure with a mechanical fixing mechanism to achieve natural ventilation and thermal management through an air buffer layer. It is widely used in high-rise buildings to reduce energy consumption and improve comfort.

System composition:

The system consists of an outer facade and an inner facade system, forming a 50-150mm ventilation cavity between the two, using the chimney effect to drive air flow; hot air is discharged from the upper exhaust port, and cold air enters from the lower air inlet, which reduces the temperature by 15-25℃ in summer and blocks cold bridges in winter, significantly optimizing the building microclimate. ‌

The circlip assembly is used as the core locking unit, embedded in the pre-set notch of the facade panel (the tolerance of the groove diameter is strictly controlled within ±0.1mm), and bolt-free self-locking is achieved through radial pressure (≥1.5kN), ensuring the panel is stable and allowing ±30mm three-dimensional displacement compensation to adapt to structural deformation.

Features:

S‌trong points: It show good performance in energy-saving benefits‌: reduce cooling load by 40%, save 40%-50% in heating, and reduce carbon emissions during the life cycle by 42%.

Weak points:‌its initial cost is a bit high‌ and High complexity in design and construction
