Louvre Windows provide very little resistance to the air entering through the window opening. 

Getting twice as much ventilation as you would through the same sized sliding window or double-hung window. Louvres can be incorporated into houses and commercial buildings in a range of ways to provide additional ventilation when required. Louvres can be supplied in aluminium, timber or glass and powder coated to match the joinery.
