Q-Air
Innovative Six-Layer Glass
Facade System

It is a rare thing in the construction sector when something truly innovative comes along, but
the development of Q-Air marks the arrival of a real game-changer and something that sets the
standard for energy efficiency and helps move the industry closer to a cost-effective and human-
friendly, nearly zero-energy building.
