Efficient, Responsible Manufacturing
Our plants
Two of our production plants are located in protected areas, where we uphold the highest environmental standards. Our manufacturing process is tightly controlled, recognized for its reliability, and optimized for low energy use—consuming just 4 kWh per m².
We generate no hazardous waste, and our facilities are equipped with advanced gas treatment systems. Importantly, our process emits no liquid waste in any form.
Thanks to cutting-edge recycling technology, we incorporate an average of 45 - 51% post-consumer material, recycling up to 51,400 tons of waste each year.
These efforts have helped us achieve a positive carbon footprint of just 5.49 kg CO₂/m² and 4.46 kg CO₂/m² for ISOLINE sheets, setting us apart from conventional roofing material manufacturers.
Sustainable by Design
Materials
All of our roofing products and materials are lightweight, which not only facilitates transportation but also enables designers to create a lighter structure to support the roof. It also means the roof requires less wood and steel, and the professionals handling our products suffer less physical stress. Furthermore, waste on the construction site is significantly reduced.
All our products are asbestos-free, composed of recycled fibers and use natural pigments for coloration.
Our proofs are assessed by reliable third-parties
