Layer structure usually applied onto the glass surface by a CVD or PVD process to influence the spectral properties of the component such as transmission and reflection. Such coating is essential for energy conserving glazing where IR radiation may be controlled by this layer. There are several coating classes which are distinguished as follows:

  • Hard Coated (HC): This describes a type of coating or covering a glass surface in a way that the resulting surface is rather resistant against damage, at least at a similar level as compared to standard Floatglass. In a composite, the surface may be exposed to the environment.
  • Soft Coated (SC): This describes a type of coating covering a glass surface resulting in a surface that is more vulnerable by environmental conditions such as moist, dirt etc. Soft coated glass panes require more care in processing.
  • Coated with foil protection (FC): This describes glass panes where the coating (typically a soft coating) is protected against environmental influence by a foil that might have to be removed when the glass is to be processed.

A job is defined as the concrete implementation of one or more programs or recipes by using a given order to produce something.

A set of jobs.

Large format glass panes as produced from float tanks at flat glass production plant. The size is typically 6000*3210 mm.

Specifies how the surface structure is aligned.

The term “Significant Side” is used if there is a necessity to distinguish which side of a glass pane is “up” or “down” or “front” or “back” while processing the glass pane. Typical examples are:

  • When producing flat glass, one side is floating on the tin bath, the other is exposed to the gas fire heating the chamber.
  • If the glass is coated (a thin metallic layer is applied), it is essential to know which side is coated
  • Glass having patterns or other surface treatments
