MAXIMUM Daylight with energy efficiency

The energy-efficiency qualities of structural components have become an all-important factor in contemporary construction and Passivhaus design, as the highest standard of energy efficiency.

The concept of ultra-high-efficiency Passivhaus design is now wellestablished among the UK design community, and architects have embraced the idea to deliver high standards of comfort and health, whilst reducing building energy usage.

Certified Passivhaus rooflights are an essential feature in contributing to the achievement of such high levels of efficiency in the design and construction of Passivhaus buildings. By providing natural daylight and ventilation, building users require very little energy for lighting, heating and cooling.

The LAMILUX Glass Roof PR60 Passivhaus sets the benchmark for energy efficiency standards for atrium glazing. It has been independently assessed by the

Passive House Institute and awarded the highest efficiency rating - the phA advanced component classification. The system features a ucwi value for the complete skylight of <= 0.82 w/ m²k, utilising warm edge triple layer glazing with ‘super spacer,’ as standard.

For smaller areas, the LAMILUX Glass Skylight FE Passivhaus flat roof modular Passivhaus rooflights offer an outstanding solution, with a USL value of <= 0.84 W/m²K. Minimum heat loss is achieved due to the frame system design whilst the narrow frame profiles maximise solar gain.

As well as state-of-the-art thermal performance, both LAMILUX Passivhaus rooflight systems offer excellent aesthetics with a wide range of sizes, options and accessories.

All LAMILUX Passivhaus rooflights feature:

• Independent certification by the Passive House Institute

• phA Advanced components: the highest efficiency class

• Easy PHPP calculations: data pre-loaded in PHPP software

• Isothermally balanced structure: 12.6° isothermal line remains within the rooflight structure, thus preventing condensation and mould formation, improving comfort & hygiene

• Eliminated risk and the associated costs of failure you face if using non-certified components

• Insulated upstand kerb: covered by certification with a U-value of just 0.3W/m²k and supplied as standard with the modular flat roof Passivhaus rooflights - it provides the perfect structural roof interface

• Design freedom: glass roof system can be installed ≥ 3° pitch, meaning you can design atriums any shape, size & inclination

LAMILUX have worked on the majority of the exemplary Passivhaus projects in the UK, including Harris Academy Secondary School and George Davis Medical Building at University of Leicester. Each Passivhaus project demonstrates stringent installation quality control measures and a competent and suitably trained workforce – this is extremely important for achieving the correct installation interfaces.

The importance of high-quality components and expert advice on Passivhaus buildings is essential, which is why with the LAMILUX Passivhaus Skylights and Glass Roofs, you are in safe hands in terms of energy efficiency and technical support.
