Glass Skylight FE Passive house

The Glass Skylight FE Passive house has been certified by the Passive House Institute in Darmstadt, Germany. This skylight therefore meets the criteria for Passive House - 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
