LAMILUX renovation solutions

Your advantages at a glance

The redevelopment and renovation of buildings will characterise the future of construction for quite some time. Not solely old roofs need to be renovated, but early inspection and renovation of a new roof will not only save time, but above all costs.

When was the last time you took a closer look at the condition of your flat roof? Inspection and maintenance are often put off as long as everything is still working. However, it is only a matter of time before the renovation of Skylights, fresh air or SHEV Systems on the flat roof is urgently required - be it due to age-related leaks, weather damage, lack of energy efficiency or insufficient fall-through protection.

If this is the case, it is time for a comprehensive renovation of the flat roof and skylights, which brings many advantages in the long run: in addition to more daylight, fresh air supply and safety in existing buildings, the customised renovation solutions from LAMILUX also contribute to an increase in property value and increased energy efficiency. As a specialist in renovation solutions, LAMILUX provides you with customised, energy-efficient and cost-effective support from the beginning to the end of the renovation project. At LAMILUX, we can, for example, carry out the renovation of your Continuous Rooflight during ongoing operation, keeping disruption to a minimum.

There are also a number of grants available speak in favour of flat roof renovations. Individual measures that aim to achieve higher energy efficiency compared to reference buildings, such as the installation of new skylights, are eligible for funding. As Europe's leading manufacturer of Skylights, LAMILUX offers a wide range of customised product solutions for your renovation project. Whether Rooflight, Continuous Rooflight, Glass Skylight, Glass Roof, fire protection window or SHEV system - LAMILUX focuses on energy-efficient renovation, as we are convinced that it not only reduces energy costs, but also makes a significant contribution to supporting sustainability. By modernising and optimising buildings, we are striving for a resource-saving future in which environmental aspects and energy efficiency go hand in hand, thus enabling our customers to act in an ecologically responsible way and achieve economic benefits at the same time. The installation of solar power systems is also subsidised, and LAMILUX photovoltaic solutions can also come into play here.

No matter what you choose, as experts in flat roof renovation, our competent LAMILUX team not only offers a wide range of innovative skylight solutions and renovation frames, but also comprehensive renovation services from a single source. From planning to installation, our experienced specialists are on hand to help you realise your visions and individual requirements for environmentally friendly renovation.

Renovation made easy

Renovation solutions from LAMILUX


Our LAMILUX Rooflights stand for greater stability and safety under severe weather conditions, as well as simplified assembly. We offer customised solutions and renovation frames for the renovation of your circular or square Rooflights, which combine diversity and flexibility on the industrial roof. As an optional upgrade, fall-through protection can easily be integrated as part of the renovation. Thanks to a clever geometry that favours efficiency rather than more material, the Rooflight is equipped for future challenges. In this context, the architectural style and choice of materials play a decisive role in the longevity and efficiency of the flat roof.

Continuous Rooflights

Our LAMILUX Continuous Rooflights have proven themselves for decades on the roofs of industrial buildings, as their functionality for hail resistance, air and water tightness and snow and wind load exceed regional requirements for weathering and are tested for durability beyond the legally specified level. We also ensure maximum safety by making our LAMILUX Continuous Rooflights completely fall-through-proof and enabling the integration of natural ventilation, smoke and heat extraction units (NSHEV), which provide employees with sufficient daylight and fresh air and effectively extract smoke from the building in case of fire.

Glass Skylights

LAMILUX Glass Skylights are available in many versions for every application. Our Glass Skylights in both circular and square shapes are customised and can be installed on the on-site upstand using our renovation frame, regardless of the manufacturer.

In addition to their functionality and aesthetic design, our Glass Skylights have been awarded the Passivhaus certificate and are suitable for new buildings and energy-efficient renovations. Our Glass Skylight Passivhaus with a triple layer sealing system and insulation core not only provides the building with optimal light conditions, but also better energy efficiency.

Installation in various roof constructions such as free-form, pyramid, barrel and shed roofs creates individual and building-specific highlights. The Glass Roofs are the ideal solution when extensive illumination of the room with daylight is required. The additional integration of the flap system can be controlled conveniently and is not only suitable for air conditioning, but also as an individual renovation solution for glass constructions. LAMILUX Glass Roofs are available as Passivhaus solutions and have been honoured for active energy management. With these customised solutions, the energy efficiency of the building can be increased and energy costs can be reduced.

Fire Protection Solutions

Renovation Frames

Our LAMILUX Renovation Frames offer full compatibility. With the help of our Renovation Frames, our Skylights can be mounted on the on-site upstand regardless of the manufacturer.

With the variety of Renovation Frames, system solutions can be exchanged individually and supplemented with a heightening element according to a modular principle. By integrating the heightening element, the roof structure is raised, enabling an increase in insulation and better energy values to be achieved.

The installed skylight gains height through the integration of the heightening element, resulting in improved thermal insulation and an increased energy balance of the building.

The flat roof renovation of the Heidelberger Druckmaschinen production hall in Wiesloch focuses on daylight, safety and well-being in the workplace. 4.2 kilometres of LAMILUX Continuous Rooflight B enable a light-flooded environment. In order to comply with the existing fire protection concept, 450 integrated smoke and heat exhaust ventilation systems ensure safety for employee and machine and at the same time ensure natural ventilation. The entire renovation is carried out in sections without affecting ongoing production process.

Light and peace on the church roof

St. Paul's Church, Traunreut

Eight visually appealing LAMILUX Glass Skylights FE 3 ° were installed during the renovation of St Paul's Church in Traunreut. The sanctuary was flooded with little daylight through the old and yellowed rooflights. With dimensions of 119cm x 323cm, up to three times more light yield is possible, so that the sanctuary shines with pleasant warmth and the radiant brightness of daylight makes it even more inviting.

More stability on the industrial roof

LAMILUX renovation R-Pharm Illertissen
R-Pharm, Illertissen

Skylights are exposed to regional weather conditions on a daily basis. A lack of daylight and poor energy values in the industrial hall of R-Pharm in Illertissen showed the need for renovation. Upgraded with 23 Rooflights F100 W with clever geometry in a new wave shape, the industrial roof is better equipped for extreme weather conditions and can withstand more wind, rain and snow.

Turning old into new

Maintenance is an important topic in construction, because we can't just think in terms of new buildings. Redevelopment, renovation and refurbishment of buildings and parts of buildings is the obvious future of the industry and is also the present. This will increasingly occupy all construction professionals. That is why we are constantly working on solutions that bring daylight, fresh air and safety from above into existing buildings of all ages.

Frequently Asked Questions

When does a flat roof renovation make sense?

Whether a flat roof renovation makes sense usually depends on the individual case. Nevertheless, a flat roof renovation is recommended if the roof shows signs of age-related damage and repair is no longer sufficient. The roof is exposed to rain, wind and sun all year round without protection, so our experts recommend a roof renovation, 

  • if there are leaks and moisture in the roof area to prevent further damage to the building.
  • if the roof no longer meets current energy standards and improved thermal insulation values are strived for.
  • if there are fractures, deformations or spalling on the roof surface in order to restore structural integrity.
  • if the existing skylights are severely weathered and glazing has become opaque, preventing daylight from entering the building.
  • if the roof no longer meets current safety standards and increased stability and resilience is required.

How much will the renovation cost?

It is difficult to give an exact cost estimate for your renovation as this depends on various factors such as the extent of the renovation, the type of building, the location and the requested improvements. Costs may incur for materials, labour, permits and any additional work such as disposal or reconstruction. You may also be eligible for a government grant for your flat roof renovation. Please contact us for professional advice. We will be happy to provide you with a transparent cost estimate in a detailed quotation.

How long will the renovation take and how will comfort/production be affected during this time?

The duration of the renovation of your skylights depends on the type and scope of the renovation measures. It can take anywhere from a few weeks to several months, depending on what exactly is being renovated and how extensive the work is. During the renovation, certain restrictions may arise due to the actions carried out. These may include noise, dust, inconvenience caused by construction work, temporary interruptions to electricity or water supplies, limited access to certain areas of the building or temporary relocations during certain renovation stages. At LAMILUX, we can carry out the renovation of your Continuous Rooflight during ongoing operations. You do not have to fear any restrictions or downtimes of your ongoing production. Nevertheless, it is advisable to take precautions to reduce noise and dust. The LAMILUX renovation service will carefully plan the renovation work with you in order to minimise the impact on comfort or production.

Can I measure my rooflight myself?

Yes, in most cases it is possible to measure the rooflight yourself. It is important to note, though, that accurate measurements are essential for a successful renovation or replacement. LAMILUX is specialised in skylights and offers renovation checklists that can help you prepare for the replacement or renovation of rooflights. These checklists provide you with additional guidelines and recommendations to ensure that your self-measured data are correct and the new rooflight fits well. If you have any questions or specific requirements, please feel free to contact our team of experts.

When does the rooflight dome or the continuous rooflight need to be replaced?

We recommend replacing the rooflight shell or continuous rooflight in particular if 

  • Extreme weather events and the age of the material have led to cracks and holes
  • Glazing has become opaque preventing daylight from entering the building
  • Unnecessary heating energy leads to high annual fixed costs. The energy requirements can quickly become significantly higher, especially if the use of the building is changed

Is it possible to replace panels on continuous rooflights?

It is generally not possible to replace the panel glazing while retaining the old supporting structure. The building authority approval of older supporting structures usually does not cover today's panel types, which excludes a combination. Moreover, the complete renovation of the continuous rooflights, including the support and sealing system, ensures the function and tightness over the service life of the new panels and is therefore the more sustainable solution. 

Is fall-through protection of the products mandatory?

Although there is no general obligation for all rooflights on all roof surfaces to be fall-through-proof, this is always a safety benefit for anyone who has to access the roof and is strongly recommended, even where there is no legal obligation to take safety measures. Taking the appropriate measures for fall and fall-through protection is of fundamental importance on roofs. The applicable regulations are as varied as the structural and logistical situations. Only a thorough case-by-case assessment by qualified specialists can provide the necessary safety.
