Constantin von

Hi! My name is Constantin and I started dreaming in 2016 and in 2018 with the realization of a motorhome self-build on all-wheel-drive truck basis. For my construction I wanted slope-compatible, insulated real glass windows. Windows that don’t cost a fortune are still lightweight and durable. After a lot of research and preparation, I built the perfect aluminum window myself. The feedback on the prototypes on Instagram and in conversations with other vehicle manufacturers was overwhelming. Good and well thought-out products that make daily pleasure have been my passion for a long time. That’s why I founded Extreme in 2020. To offer good windows, doors and other ideas to all the travel crazies.”
