4. Two sides fixed frame glass curtain wall
The glass panels of the conventional frame-type glass curtain wall are fixed all around (adhesive bonding or frame support fixing). In addition, there are particular forms in some designs where only two sides support and set the glass panels.
In these cases, the upper and lower sides fix the glass panels, and the fixed side is generally the long side direction of the glass panel. This kind of glass curtain wall has no vertical columns or a distance between the vertical columns and the surface of the curtain wall.
The upper and lower sides of the glass panel are fixed on the metal beam in the horizontal direction of the exposed frame or hidden frame glue. The other two sides of the glass panel (in the vertical direction) are directly sealed with glass glue and even left as an open seam. (When the curtain wall is required to be airtight).
This glass curtain wall reduces the contact between the metal profile and the glass surface. It is more transparent and novel than the conventional frame-type curtain wall, and the horizontal lines are more prominent. Therefore, it is more suitable for the glass with high transparency.
In addition, there are also left&right sides fixed types of curtain walls. This type must carefully consider how the structure overcomes the long-term gravitational influence of the glass panel.
