Alfa Roof 28/2,5
Alfa Roof 28/2,5 is a twinwall corrugated sheet designed for use in the industrial, light commercial and farm building sector. More specifically, the sheeting finds application in roofing in conjunction with steel or aluminium corrugated profiles and in fully glazed roofing. It can also be used for producing curved single-pane or continuous skylights and shed. Developed using the latest innovative co-extrusion technologies, Alfa Roof 28/2,5 comes in a 2.5mm-thick sheet with a 9-rib profile to suitably cater to various different types of application in the construction industry, where wide-ranging building needs mean it has a wide and varied field of application. Alfa Roof 28/2,5 brings out the best of polycarbonate’s mechanical and physical qualities, delivering high standards of application, which are essential in particularly innovative designs.

Behavior under environmental conditions
Alfa Roof 28/2,5 sheeting is protected against the harmful effects of UV rays. This protection is provided by means of the co-extruded application of a special treatment designed to ensure lasting optical, mechanical and performance qualities. With the cells sealed by heat sealing the ends of the sheet with hi-tech instruments, there is less chance of condensation and impurities building up inside the cells.
