Planar Glazed Casement Solution

The Lumera is the solution for smoke and day-to-day ventilation in horizontal and low pitch structural glass roofs as the ventilator is planar glazed.

The Lumera extracts large volumes of smoke, utilizing the buoyancy of hot gases in the rising plume.¬†Natural day-to-day ventilation is driven by pressure differences to move fresh air through the building. Pressure differences are caused by wind or the buoyancy effect created by temperature differences commonly known as the “stack effect”.

The Lumera is double glazed, electrically or pneumatically controlled.
