Design details

Smoke Lift Glass Skylight Passivhaus technical design characteristics

Energy efficiency

The Smoke Lift Glass Skylight FE Passivhaus fulfils the requirements as a certified Passive House efficiency class: phC component with its heat transfer coefficent USL of 0.85 w/(m²k). Featuring a triple step sealing system alongside its optimised insulation core, the aluminium framed quadruple glazed FE Passivhaus smoke ventilation rooflight 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 (diagram available on request) 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.
