ABSTRACT:
An automatic method and device for filling, with gases other than air, insulating glazing units. The method entailing a step for injecting the gas and expelling the air so as to produce a laminar flow through a manifold constituted by the hollow region of the profile that forms the spacer frame. The method and the device allow a considerable saving in costs, reducing the amount of gas required for filling to an amount very close to the volume of the inner space provided in the insulating glazing unit.
