The 50 mm wide aluminum cover profile used on the exterior surface of the curtain wall system can be designed in many different geometric forms according to the demands of architects. The glasses are mechanically attached from the outside with a pressure strip on the horizontal and vertical axes. The air and water tightness of the system is provided with EPDM wicks used inside and outside. The cover profiles on the horizontal or vertical axis used on the exterior can be optionally canceled and silicone is applied to the joint gaps instead of these profiles. Thus, when viewed from the outside, the desired form is obtained on the facade surface vertically or horizontally.
