Onduline's Commitment to Sustainability
At Onduline, sustainability isn’t a trend—it’s a long-standing commitment. Our roofing experts deliver innovative solutions that protect people from the elements, while our products and processes give back to the environment through responsible, eco-friendly practices.
Sustainable Production
Zero dangerous waste
We take great care in designing manufacturing processes that are energy-efficient and generate no hazardous waste.
Through advanced recycling technologies, we recover and reuse an impressive 51,400 tons of material annually.
These best-in-class initiatives have helped us achieve a positive carbon footprint of just 5.49 kg CO₂/m² for our roofing sheets and 4.46 kg CO₂/m² for ISOLINE® underlay sheets—outperforming traditional roofing material producers.
