The hidden mullion curtain wall is a façade solution in which the aluminum framing system is concealed behind the glass, creating a seamless glass surface when viewed from the outside. This structure uses mechanical fixings and structural sealant to secure the glass to the frame, ensuring wind load resistance and structural stability in accordance with curtain wall design standards.
Hidden mullion systems are commonly applied in projects that require a flat, minimalist architectural surface with reduced visible divisions, while still meeting technical requirements for drainage, material expansion, and maintenance during operation.
