In the paper three types of multiwall panel in co-extruded polycarbonate were investigated considering different alveolar structures. They could be considered representative of a wide range of polycarbonate systems: few chambers, many chambers, intermediate number of chambers with major geometry complexity and they could represent a possible and cheaper option for non-residential buildings instead of standard glazing façades.
They present different geometric characteristics of the cell, but they have the same total thickness (0.04 m). Type S3 consists of three walls, two external layers (about 1 mm thickness) and an internal one (0.14 mm thickness), with and a double-chamber with air. The polycarbonate panel S5 has a multi-wall section, with triangular shape of the internal structure. Finally, Type S9 consists of nine walls and eight chambers. In all cases, the outdoors layer is UV protected.
The panels are manufactured with a maximum width of 0.435 m, so they need to be installed in buildings thanks to male–female joints that could be a weak point for the façade.
Table 1 shows the main characteristics of the examined samples
