Like the Luma, the Lumera is an architectural ventilation window for high quality natural ventilation.

1.- Frame. 2.- Opening mechanism.
Lumera is a ventilation window for smoke exhaust and natural ventilation which can be mounted at an angle of 0 to 90º. The opening angle of the window in relation to the base is variable up to a maximum of 90º. As a result, Lumera model is suitable for both day-to-day ventilation and smoke exhaust. Lumera consists of cold bridge-free aluminium profiles ensuring a high insulation value is attained. Although Lumera is usually supplied with insulated glass, uninsulated glass (or some alternative panel) is also possible on request. Delivery, installation and sealing of the (glazed) panel can be carried out by third-parties on site.
Examples of this are the concealed controls and the glass fixing, which are not visible from the outside. If required, Lumera can be anodized or powder-coated (in any RAL colour).
