VentilationThere must be an adequate ventilation space (min. 20 mm) between the Liberta 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 struc- ture to ensure free air change. The lower edge of the Libertas has ventilation holes, through which the water that has entered the structure through the joints or is caused by condensation can be removed. The ventilation holes are oval, of 5 x 15 mm in size. The holes are prepared as described in the fastening hole instruction above, independent of the customer-specified fastening hole positions. The outermost holes are placed 60 mm from the Liberta ends.Facade flashings
