Glass Skylight FE Passivhaus

The Glass Skylight FE Passivhaus has been certified by the Passive House Institute in Darmstadt, Germany as a “pha Advanced Component”, the highest Passive House efficiency class. This skylight therefore meets the criteria for one of the most sustainable trends in contemporary construction and is suitable for the most demanding type of energy-efficient construction. The Passive House efficiency classes take into account heat loss and solar energy gain. Minimum heat loss is achieved due to the frame system design providing excellent U values and low glass edge Ψ-values. In addition, the narrow frame profiles maximise solar gain
