Through conscious design choices and a thorough testing programme according to multiple international standards, Reynaers Aluminium solutions lift your project to a whole new sustainable level. Enjoy verified and certified quality that lasts a lifetime. *Eco Design* ## There are many aspects of Eco Design that we consider. ![Bald man in blue shirt dismantling wooden window from residential construction site.](/sites/default/files/public/styles/tabbed_block/public/2026-08/Reynaers-Aluminium_22.jpg?h=a141e9ea&itok=Qi-mNj5e) ![Warehouse employees assembling aluminium frame.](/sites/default/files/public/styles/tabbed_block/public/2026-08/RA_shoot_23_april_2025-224.jpg?h=f0ab467d&itok=KvYzTFrA) ![Pile of aluminium scraps.](/sites/default/files/public/styles/tabbed_block/public/2026-08/154608F0002-REYN.jpg?h=2992ba0a&itok=QuN74TaQ) ![Prefab façade with window being lifted to high-rise building under construction.](/sites/default/files/public/styles/tabbed_block/public/2026-08/Doktoren%20Antwerpen-0546-0321%20%281%29.jpg?h=24e1030f&itok=fe5NnpoM) ![Gloved hand toucing black aluminium window profile on site.](/sites/default/files/public/styles/tabbed_block/public/2026-08/Reynaers-Aluminium_84.jpg?h=877b9b2b&itok=6i2ArmHE) ![Three men in blue shirts looking at papers.](/sites/default/files/public/styles/tabbed_block/public/2026-08/Reynaers-Aluminium_32.jpg?h=99ce605d&itok=Ul3yc1hS) ![Woman looking out of window of office building.](/sites/default/files/public/styles/tabbed_block/public/2026-08/RA_shoot_23_april_2025-140.jpg?h=f0ab467d&itok=laHbgsqH) ### Design for disassembly When systems are easy to dismantle at end of life, their materials can be sorted and recycled more efficiently. ### Design for adaptability and flexibility Through smart design choices, we make it easier to adapt our windows and doors and extend their lifetime. ### Design out waste We avoid throwing away precious materials by optimising material use already at the design stage. ### Design in modularity With modular systems, you can give your building a second life as its purpose changes over the years. ### Design with less Fewer materials required means lower carbon emissions, it is that simple. ### Design with fewer hazardous materials Less is more, especially when it comes to high-risk components. ### Design to increase the lifespan We create solutions that last a lifetime, for people today and future generations. ![Man kneeling at AWW test wall wearing safety gear.](/sites/default/files/public/styles/portrait_small/public/2026-08/RA_shoot_23_april_2025-200.jpg?h=281ff0f2&itok=mt47AiCj) ## Testing for certification Since 1965, we have been improving our aluminium systems to meet the strictest performance standards of today, and anticipating the customer needs of tomorrow. And with a global climate that is rapidly changing for the worse, the **need for continuous improvement** is real. The Technology Centre in Duffel, Belgium is one of the largest privately owned joinery testing facilities in Europe. Here, we push our systems to the limit according to different international standards. We check how our systems perform in **extreme weather conditions**, but also their **energy efficiency, safety and security levels, and user-friendliness** are closely monitored. A lot of our systems carry important sustainability labels, like **Cradle to Cradle, Passive House and Minergie**. These labels objectively prove that our systems can help you create more futureproof buildings and achieve green building certificates in the process. ## Sustainability starts with asking the right questions.
