2. Application technichal notes

As the individual sheets in a laminate, the advantages of PLANIDUR combined with the lamination become evident in that it has the safety characteristics of laminated safety glass. Specific national, regional or local codes and/or standards for application of heat-strengthened glass can differ significantly. The purchaser is responsible for the prevailing requirements.

  • The thermal tempering requires that subsequent treatments to the glass such as cutting, grinding, drilling etc. are not carried out. This can result in breakage or at least in a reduction of the material characteristics of the glass! All finishes to the glass must therefore be carried out prior to tempering.

  • Anisotrophy: Irrisation occurrences in thermally treated glass. In viewing the heat-strengthened glass under certain light conditions and polarised it is possible that a pattern in the glass becomes visible. This is Anisotrophy or so called polarisation fields. This is a physical phenomenon and a normal characteristic of HS glass.

  • Moisture uniformity on the glass surface
    The surface moisture uniformity on the outside of the glass may vary e.g. due to imprints from rollers, fingers, labels, paper residue, suction pads, sealant residue, smoothing agents, separation agents or environmental influences. Moisture on the glass surface as a result of condensation, rain or cleaning water may have differing levels of uniformity. Such appearances are inherent characteristics and cannot be considered as defects.

  • The sizing and application of PLANIDUR must comply with applicable standards and building codes.
