In order to cover structural elements in all-glass construction or to protect the edge seals of insulating glazing against UV rays, glass panes are often provided with edge enamelling. No removal of edge coating takes place with TEA edge enamel (True Edge Application). Instead, the enamel fuses with the coating of UNIGLAS® energy-saving, noise protection and sun protection insulating glass to form a permanently stable bond.

With a thermal break and very minor disturbances in the insulating plane, a very massive connection to the static load-bearing structure is possible in variable design versions. Adjusting pieces can be used at any point (according to statics) on the railing suspension profile, which is already bonded to the glass in the factory. As a result, no processing etc. on the profile is required and the glass railing is easy to design, plan and execute in almost any situation.

By means of TEA edge enamel, a material-dissolving ceramic paint (enamel) is applied directly to the magnetron sputter coating. This is dissolved during the heat treatment and fuses with the glass to form an extraordinarily stable bond. After cooling, the coating material is completely embedded in the enamel.


  • aesthetic: structural elements become invisible.
  • high quality: sensitive coatings are protected much better.
  • fast: the complete production takes place in-house – decisively shortened delivery time.
