Public buildings should determine the heat transfer coefficient and shading coefficient of the transparent part of the glass curtain wall based on the window to wall ratio and shape coefficient, while public buildings should determine the heat transfer coefficient and shading coefficient of the transparent part of the glass curtain wall based on the window to wall ratio and shape coefficient. So, what are the basic and performance parameters of glass curtain wall construction? Learn more about the following content!

1、 Basic parameters

The horizontal expansion modulus of the building curtain wall is increased from 900mm to 6000mm, and the vertical expansion modulus is increased from 2700mm to 6000mm. If the project needs to cross the above dimensions, it can be studied separately with the manufacturer.

2、 Performance parameters

1. Wind resistance performance: The standard value of wind load should not be less than 1.0kPa. The deflection limit of glass ribs should be taken as L/200 of their calculated span. Technical performance of high-rise glass curtain wall insulated glass and laminated insulated glass

2. Water tightness performance: The water tightness of fixed parts in areas affected by tropical storms and typhoons should not be less than 1000Pa, the water tightness of fixed parts in other areas should not be less than 700Pa, and the water tightness of open parts should not be less than 150Pa.

3. Airtightness performance: It should not be lower than level 3, and the air permeability at the fixed joint should be 0.05 q ≤ 2.5m3/m · h.

4. Thermal insulation performance: The heat transfer coefficient and shading coefficient of the transparent part of the glass curtain wall in public buildings should be determined based on the window to wall ratio and shape coefficient, in accordance with the provisions of GB50189-2005 "Energy saving Design Standard for Public Buildings".
