Standard tempered glass is produced with isotropy values between 55 % and 80 %, making anisotropy visible depending on the degree of polarization in light, angle of observation and thickness of glass. This poor quality is accepted by industry standards. However, the argument that it cannot be avoided is a thing of the past.
Arnold Glas has developed a new production process and measuring tool that allows for tempered glass to be produced with an anisotropy value smaller than 5% and thereby eliminates visible anisotropy. The product is called topview.
Anisotropies diminish the visual quality of a glass surface and topview reduces them to such an extent that the human eye no longer perceives them as disruptive. This means that architectural design concepts are exploited to their best advantage – a distinct quality bonus for architects in particular.
