平开式门窗
平开式门窗
Flat-open doors and windows
开启操作：将控制执手像玻璃内侧旋转90度，拉动执手开启门窗。
Opening operation: The control handle rotates 90 degrees like the inside of the glass, and pulls the handle to open the door and window.
关闭操作：将开扇推至闭合状态，按开启操作相反方向将控制执手旋转90°。
Closing operation: Push the fan to the closed state and rotate the control handle 90 degrees in the opposite direction of the opening operation.
性能优势：平开窗一般采用胶条密封，效果优于毛条密封；开启扇部位较多的采用两点锁或天地锁进行锁紧密封，因此在门窗的三性能(抗风压性、水密性、气密性)方面，平开窗普遍更具优越性。平开式门窗的开启面积大，通风好。如果是向内开式的话，擦窗也十分方便。
Performance advantages: flat windows are generally sealed with rubber strip, which is better than wool seal; open fan parts are mostly sealed with two-point lock or Heaven-Earth lock, so in the three properties (wind pressure resistance, water tightness, air tightness) of doors and windows, flat windows are generally more superior. Flat-open doors and windows have large open area and good ventilation. If it's open inward, it's very convenient to clean the windows.
