Skylight Ventilation
Stardome skylights provide ventilation, refreshing the air supply through extraction of old, stale air. There are many different skylights available. Performance levels differ from product to product, as displayed in the table below.
Skylight Mechanical Ventilation
Under certain circumstances a more assured form of ventilation may be needed, where quantifiable air exchange performance is required. In these instances, a power fan can be fitted to the skylight unit.
