Abstract: A method for obtaining glass panels for curtain walls, which comprises the following steps: positioning a first pane on spacers associated with a table which can move longitudinally and is provided with a vertical support; resting the lower perimetric edge of the first pane on the vertical support; temporarily locking the first pane fixing a spacer profile at a chosen distance from the perimetric edge of the first pane; moving the support away from the lower perimetric edge of the first pane; treating the surfaces of the mutually contiguous regions of the first pane, of the spacer profile and of the frame by means of a plasma torch; positioning said second pane so that it rests against the spacer profile, so as to be arranged approximately parallel to the first pane, and applying a chosen pressure to the second pane toward the first pane; applying a structural sealant in a cavity formed between the spacer profile, the first pane, the second pane and the frame.
