OPENMAX PREMIUM, the new generation of multi-sash.
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.

To sum up, easy lines and minimal structure for an extremely safe and versatile system.
