The multilayer corrugated metal sheet Ondulit finds extensive application in building roofs in urban areas, historical contexts, and industrial archaeology. The symmetry of its profile provides a harmonious aesthetic impact. Its ability to curve both concave and convex surfaces makes this sheet particularly versatile. Ondulit is an excellent substitute for asbestos without compromising the acoustic characteristics of indoor spaces. It is a Cool Roof corrugated metal sheet, thanks to its high solar reflectance coating on the outer surface. Moreover, it allows seamless integration with photovoltaic systems through the use of the Easyfix system.
