Lichtkuppeln sind eine beliebte Lösung, um natürliches Licht in die Innenräume von Gebäuden zu bringen.

Natural light is an important source of energy for humans in general and increases well-being as well as physical and mental performance. But how does such daylight best get into buildings? Find out more why rooflight domes have been the go-to solution for decades:

Dome skylights illuminate large office, administrative and industrial buildings with plenty of natural light and are very economical because they combine three functions at the same time: They enable energy-cost-free lighting through daylight incidence, provide natural ventilation and ensure safety in case of fire through integrated smoke and heat extraction systems (SHEVS). The requirements for a good rooflight dome are just as varied as its functions. After all, rooflight domes must be able to cope with individual building types and requirements. That's why the focus of a good rooflight dome is on flexibility, quality, energy efficiency, ease of use and service.

1. Flexibility for individual solutions for rooflight domes

Architects and roofers work on different projects every day. Whether it's an educational institution or an industrial hall, a new building or a renovation project: thanks to the wide variety of designs, numerous glazing combinations and individual accessories, a rooflight dome adapts perfectly to every requirement. There is a large selection of skylight dome designs: whether they are angular, square, round or inclined in terms of construction or ventilated, rigid or SHEVS in terms of use. Specialists in daylight systems, such as the Lamilux Heinrich Strunz Group, actually develop special shapes. The rooflight dome package is perfectly rounded off with individual accessories. For example, if the energy requirements are higher, flat roof windows made of real glass can be used instead of plastic skylight dome glazing. Luxurious flat roof exits, for example, provide special highlights on the roof.

2. Quality ensures durability of rooflight domes

What would a good rooflight dome be without quality and stability? The edging frame and the skylight upstand play a decisive role here. The edging frame must ensure stability, protect the glazing with good thermal insulation and also comply with the industry standard DIN 18234 for large-area roofs. The frame is supported by the upstand. Particularly upstands made of glass-fibre reinforced plastic (GRP) ensure a long service life of the rooflight dome, because GRP is, among other things, extremely weather and hail resistant, corrosion resistant, temperature resistant and robust. If the GRP skylight crowns also provide more quality and an aesthetic appearance thanks to their seamless interior, nothing stands in the way of the rooflight dome's longevity.

3. Energy efficiency for the highest requirements

Anyone who thinks that rooflight domes only provide daylight, fresh air and safety is mistaken. Thanks to multi-stage sealing systems, multi-skinned plastic glazing, thermal-bridge-free designs with optimal isothermal processes and compact system tightness, the rooflight dome has become a true energy miracle. David Plaetrich, Sales Manager at Lamilux, has been working in the market for daylight systems for almost 30 years and has been involved in the development of rooflight domes from the ground up: "You could almost call the rooflight dome the mother of all skylights. We have been planning, manufacturing and installing rooflight domes for over 70 years and have been constantly improving since then - in every step of the process, in quality and in performance. Today, a rooflight dome covers much more than daylight gain. It is a true energy and safety system."

4. User-friendliness during installation of rooflight domes

Of course, there must be no problems during installation on the roof. That is why the rooflight dome is best delivered to the building site already completely pre-assembled and in safe and environmentally friendly wooden crates. This saves the roofer a lot of time during installation and guarantees user-friendly installation on the roof.

5. Reliable service

What is also essential for a good rooflight dome is the service for planners and installers. This includes comprehensive and personal advice, fast and reliable delivery as well as competent service for repairs. Professionals who have specialised in the construction of rooflight domes for decades enable the uncomplicated implementation of every desired project through reliable support. Individual, high-quality and energy-efficient rooflight domes create light-flooded buildings, wholesome working atmospheres and happy people.
