Support studs are fixed to outer skin of the base structure from both flanges with overlap screws (‘Screw S1H48023L02A4’) c/c 250 mm. Studs with only one flange (e.g. CA1RS1) are fixed c/c 125 mm.If base structure flatness can’t be ensured, i.e. panels are not forming even surface (e.g. due to tolerances in load bearing frames) to cladding material, adjustable Ruukki studs have to be used. Adjustable Ruukki studs can accommo- date up to 30 mm tolerances.VentilationThere must be an adequate ventilation space (min. 20 mm) between the Design profile and the base wall structure enabling an unobstructed air change. It must also be ensured that there are gaps in the upper and lower edge of the wall structure to ensure free air change.Facade flashings
