LAMILUX Glass Skylight FE Passivhaus
Independently tested & certified by The Passive House Institute in Darmstadt as a phA Advanced rooflight for flat roofs

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 have excellent U values and low glass edge Ψ-values. In addition, the narrow frame profiles maximise solar gain.

Glass Skylight FE Passivhaus technical design characteristics
Energy efficiency
The Glass Skylight FE Passivhaus fulfils the highest Passive House efficiency class: phA advanced component with its heat transfer coefficent USL of 0.68 w/(m²k). Featuring a triple step sealing system alongside its optimised insulation core, the aluminium framed triple glazed FE Passivhaus skylight offers maximum energy efficiency and thermal insulation. With high levels of wind and rain resistance, alongside enhanced isothermal characteristics in the overall construction – the unrivalled performance of this range results in no condensation alongside excellent air tightness values. The thermally broken “isothermally balanced”aluminium frames feature optimally aligned 12.6° isotherm line. This means that the thermally broken 12.6° isothermal line remains within the structure (see diagram) for consistent heat insulation without any weak spots, reducing condensation, mould and bacteria. The TIP (Total Insulated Product) is certified in accordance with EN ISO 14021.
