Monitoring components

In-house and external monitoring of the primary products of multi-pane insulating glass was introduced with the Quality and Inspection Regulations RAL-GZ 520 of May 2016:

 

  • Spacers
  • Desiccants
  • Sealants

 

This resulted in a further strengthening of the continuous quality chain.

These components too are now subject to in-house and external monitoring. Only those components that are on the quality-monitored components list in its latest version may be used for the production of multi-pane insulating glass bearing the RAL quality mark.
