Sustainability

At GRENS, sustainability is at the heart of everything we do.

As an authorized manufacturer of Reynaers systems, our products ensure low-energy operation, resilience in extreme weather, and durability throughout their entire lifecycle. We source aluminum produced with renewable energy, use certified and traceable materials, and design systems to be modular, recyclable, and easy to disassemble when their lifespan ends. Guided by Reynaers’ “Reynaers Act” programme, we are dedicated to protecting the planet and taking responsibility for the environment, ensuring that every window, door, or façade we deliver helps build a more sustainable future.
