GLASS SPECIFICATIONS FOR VISUAL ACCEPTANCE IN ARCHITECTURAL APPLICATIONS

Glass specifications are nowadays very project specific and are typically written by façade experts and consultants. The requirements contained therein are typically more demanding than those published in glazing industry standards and codes: this is done in order to achieve higher performance and improved visual appearance. In recent projects this resulted in several technical queries related to the finished glass product: their resolution required extensive dialogue with the glazing industry.

Several methods aimed to deliver the desired and specified visual quality have been developed and are successfully used. Examples of challenges that we have tackled and that will be presented are the stripping of performance coating, the test method to assess the effect of visual distortion on curved glass, the test method to assess visual distortion on climatic pressure differences and the management of client expectations via a project specific protocol.

Conversely, the current glazing industry standards, codes and guidelines should be revisited and updated to reflect the increased capabilities of the glass and façade industry, and to incorporate vital visual acceptance criteria. This should enable clients to rely on agreed industry standards and documents rather than project specific and custom made requirements.
