Tvitec partnered with Forel to create a new “No Limits” jumbo insulating glass unit line for Tvitec. The new jumbo line was designed to produce glass for façades and special glass types. The project was completed over a period of two years, and has been delivered to Tvitec’s factory in Ponferrada, in northern Spain.

“The Tvitec-Forel line can process some of the largest sizes of IG glass requested by today’s market,” says Stefano Salvian, sales director of Forel. “ We had to take into consideration aspects that in the past were almost marginal, such as nonplanarity, which, for extremely large-sized glass sheets can be really important. The result is a line able to adapt itself to glass sheets that are not perfectly flat – and we are talking about centimeters here – with features that are completely different from other lines, with regards to size, accuracy and types of processes carried out.”

Forel’s new line consists of a loading area, coating removal, washing machine, inspection and frame mounting, glass turning section, assembling press with gas filling and automatic sealer. The line was designed and built following a list of aims to be achieved:

  • processing single glass sheet up to 40-millimeters thickness, and insulating glass up to 100 millimeters
  • creating structural stepped units with vertical offset up to 250 millimeters and leading horizontal offset up to 1,000 millimeters
  • processing of bowed glass up to 2.5 millimeters per linear meter.
