The ventilation window is supplied with wood and aluminium so that the external part is protected from the different weather conditions.
At the same time, the ventilation window will have the same exterior design as the building's other windows and doors.
The ventilation window can be supplied as either a fixed sash window or a top-turning window.
In order to be able to clean the space between the outer and the inner glass, the inner part can be opened.
At the bottom of the ventilation window there is an air intake, and at the top is a multi-functional electronically controlled valve that acts according to a defined control system, as showed below.
Bottom of the window: Warming by shining sun and letting the cold air in-between glass layers
Bottom of the window: Cooling by direct inflow to the building
