40/3 – 40/10 – 40/25
Alfa Roof 40/3-10-25 are multiwall corrugated sheets designed for use in the industrial building sector. More specifically, the sheeting finds application in fully glazed roofing, in conjunction with polyurethane insulating panels and metal corrugated profiles. They can also be used for producing curved singlepane or continuous skylights, for shed, for vertical glazing etc. Developed using the latest innovative co-extrusion technologies, Alfa Roof sheeting comes in various shapes, sizes and thicknesses 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 sheeting brings out the best of polycarbonate’s mechanical and physical qualities, delivering the highest standards of application, which are essential in particularly innovative designs.

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.
