OpenMax Premium

OpenMAX Premium an innovative modular system that works in a very unique way; the secret is in its name, each sash places itself and slides independently, changing spaces between instances or entries to a garden or terrace. Unlike traditional folding systems, OpenMAX Premium goes unnoticed indoors, creating wide open spaces. Its exclusive system allows each sash to open independently, making cleaning and ventilation easy. To sum up, easy lines and minimal structure for an extremely safe and versatile system.
