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

Quality

• Independently tested & certified by The Passive House Institute in Darmstadt as a phA Advanced Component – the highest possible efficiency class

• Fully factory assembled product - producing a superior quality product

• Eliminates the risk of using a non-compliant component and the associated costs of failure

• Factory production approved to ISO 9001:2015, which means the quality products are manufactured to a consistently high standard

Design

• Insulated upstand is included and covered by the Passivhaus certification with a U-value of <= 0.3W/m²K - providing the perfect interface with the roof

• Easy PHPP calculations, as our product data is pre-loaded into the PHPP software

• GRP heat-insulated upstand with seamless silk-white interior finish removes the need of internal plastering

• Triple glazing as standard to fulfil the highest Passive House efficiency class: phA advanced component

Comfort

• Isothermally balanced: the 12.6° isothermal line remains within the rooflight structure, preventing condensate and mould which improves comfort and hygiene

• Effective acoustics and soundproofing with a sound insulation value of Rw,p 39dB

• High daylight incidence with a light Transmittance value of 72% (reference standard glazing)

• Increasingly pleasant indoor climate available with optional natural ventilation and sun protection

Use

• Suitable for eco-friendly, low-energy residential and commercial new buildings and energy-efficient renovations looking to achieve Passivhaus certification

• For application within flat roofs, or roofs with an inclination of up to a 25° pitch

• Providing ultra-low energy consumption for lighting, heating and cooling, and consistently good air quality

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.
