DucoWall Screening 70
DucoWall Screening 70 is a sturdy aluminium louvre-wall system with a choice of 3 different louvre-blade pitches. This enables the louvre wall to be adapted to suit the desires and needs of any project. The Z-shaped louvre blades are clicked directly onto the support section, ensuring super-quick assembly.
The smallest louvre-blade pitch of 75 mm provides a sleek appearance with almost total privacy. Conversely, the largest louvre-blade pitch of 150 mm offers excellent airflow as well as providing attractive cost savings. What’s more, it is quicker to fit thanks to the smaller number of supports/louvre blades. The happy medium is the 112 mm louvre-blade pitch with which all the plusses come together.
The large louvre-blade span (2,400 mm) means that fewer support sections are required. This results in cost savings which manifest themselves in materials and fitting.
