Lightweight Roofing Systems

Present in over 100 countries, Onduline has production sites in 8 countries in order to satisfy its customer's needs. These sites are located close to the main markets of the Group to reduce transportation costs. For about 80 years, Onduline strategy has successfully combined growth and international development. The cellulose-bitumen-based roofing  and under-roofing  material known as Onduline was invented and launched on the French market in 1944 by Gaston Gromier.  Since then, our core business has focussed on manufacturing lightweight roofing sheets made of recycled fibres and bitumen for pitched roofs. We are the undisputable leader in this segment, manufacturing more than 95% of world production of bitumen sheets.
