What if a door could be the size of a wall?

A complete wall, functioning like a door; opening and closing space. But it is not pivoted or hinged. It simply appears or disappears on demand.

Panora Vertical Retracting Door System is a modern architectural solution for large wall openings. Different than the traditional doors the Panora Retractable door systems operate with a vertical action where the panels move upwards and the border between indoor and outdoor spaces dissolves.
