[CAM Note] Shaping the glazing unit.
Gravitational bending.
This manufacturing technique is generally based on the production of a mould the size of a single modular unit. A flat plane of glass is placed into the mould and sent to furnace; it then sinks due to to its own weight and takes the form of the mould. In their final geometry , the outline of the element must correspond to the facade grid within the allowable tolerances of glass. In addition, to ensure the intactness of the different glass coatings, it is of prime importance to have accurate control of the specific furnace temperatures, as the rate at which the glass is heated and cooled affects the integrity of the glass unit.
The double glass unit should consist of 2 layers of laminated glass; each of the layers is composed of 2 single panes (outer panes : 8 mm thick, inner: 6 mm).
In the single glazing unit consisting of 3 panes of glass is used. Note: From a technical perspective, prints (i.e. printed dots etc.) on curved glass initially acts as sunscreen, improving the G-values of the glass by about 25%.
