Reliable quality
Our flat roof windows are designed to last for decades. Finished with high-quality materials that retain their value over time.
Sleek design
A Skylux flat roof window integrates discreetly into any roof. Clean lines, clear glass and a timeless appearance that suits every project and every architectural style.
Trusted by professionals
Day after day, professional roofers across Belgium rely on Skylux. We have been earning that trust for more than 70 years.
Limitless choice. Perfectly tailored to your project.
Fixed or opening
A fixed flat roof window brings in maximum daylight. An opening model adds natural ventilation: ideal for bathrooms, kitchens or bedrooms where fresh air is welcome.
Glass options
Clear, opal or solar-control glass: each glass type has its own benefits. Clear glass provides maximum light transmission. Opal glass diffuses the light more softly and offers extra privacy. Solar-control glass helps keep heat out without blocking daylight.
Applications
Skylux flat roof windows are suitable for every type of flat roof, both in new-build and renovation projects. Whether it is for a living room, bathroom or extension, there is always a size and glass type that fits your project.

Frequently asked questions about flat roof windows
Does a Skylux window fit every flat roof?
Yes, Skylux flat roof windows are designed for universal integration on virtually every flat roof with a pitch between 0° and 25° ideally at least 5° for natural water drainage.
Whether you are building a new home or renovating an existing one, our unique renovation frame even allows us to install a modern glass flat roof window on old curbs from other brands, without touching the existing roof covering.
Do the flat roof windows comply with all standards?
Absolutely. Our windows carry the CE marking according to EN 1873 and meet the strictest Belgian and European energy performance requirements. They are also fitted as standard with laminated safety glass P2A, making them burglar-resistant and safe against fall-through risks.

Can I install a flat roof window or skylight myself?
Yes, you can, as Skylux flat roof windows are also available as a complete installation kit. Installation manuals and mounting videos can help guide you through the process.
However, for complex projects or in case of doubt, we recommend working with a certified Skylux installer to ensure a 100% watertight result.

How much does a flat roof window cost?
For an exact price tailored to your project, you can easily request a quotation from our dealers. Do you only want to know the price of the flat roof window itself? Then you can always visit our flat roof window shop.
What insulation values does a flat roof window offer?
Our windows rank among the best on the market:
- iWindow3: Ug value of 0.5 W/m²K, comparable to a well-insulated wall.
- iWindow2: Ug value of 1.0 W/m²K.
- Vitria: Ug value of 1.1 W/m²K.
This allows you to save significantly on your energy bill compared with old skylights.
How do I maintain my flat roof window?
Our glass windows are very easy to maintain thanks to their flush design, which prevents water and dirt from remaining on the edges. Cleaning is simple with lukewarm water and a mild soap.
Avoid abrasive sponges or aggressive chemical products to prevent damage to the coatings.
