The system profile width is 50 mm, designated for standard facade with caps and for structural façade as well. There are three columns – 50 mm, 100 mm, 157 mm and three transoms – small one, 55 mm and 105 mm – under the cap, a cap and a structural sash. The remaining profiles come from the all other systems. The transoms assembly is possible following the system – column-transom-column or first assembly of the columns and then – the transoms through by sliding. In cases of a structural facade the 5009 glass spacer and the key profile 5010 are placed through out the whole perimeter of the insulating glass unit and then covered with a silicone.
