IG UNITS

XXL insulating glass units represent a

demanding growth market which requires

top class performances extending from the

manufacturing to the logistics. AGC Interpane

has been able to significantly increase the

productivity and precision of an existing

insulating glass line for the manufacture of

oversized glazing through the automation of

the spacer application.
